A healthy dog does not stay the same dog for fifteen years.

The puppy who needs vaccinations, growth monitoring and careful socialisation becomes a young adult.

The young adult becomes a mature dog whose weight, teeth, joints and everyday habits deserve closer attention.

And eventually, many dogs enter a senior stage where changes in:

• movement;
• appetite;
• sleep;
• behaviour;
• muscle;
• thirst;
• weight;
• and energy

can become increasingly important.

That is why preventive care should not be built around one permanent checklist.

It should evolve with the dog.

AAHA's canine life-stage guidance emphasises exactly this principle: different stages of a dog's life bring different health priorities, and breed, body size, age and individual circumstances can affect when those stages occur.

The goal of this guide is not to teach guardians to diagnose disease at home.

It is to help you understand what is worth monitoring, what should be reviewed with your veterinarian and how priorities change from puppyhood through the senior years.

Key takeaways

• Every dog should have a preventive-care plan appropriate to their age, breed, health, lifestyle and location.
• Puppies require particular attention to vaccination, growth, nutrition, socialisation, congenital problems and parasite prevention.
• Adult dogs still benefit from regular wellness care even when they appear completely healthy.
• Body weight alone is not enough; body condition and muscle condition also matter.
• Dental care should begin early and continue throughout life.
• Vaccination plans should be individualised rather than copied from a universal calendar.
• There is no universal age at which every dog becomes senior. AAHA defines the senior stage broadly as approximately the final 25% of expected lifespan.
• Senior dogs often need closer monitoring and may benefit from more frequent veterinary assessment and screening.
• Changes in appetite, thirst, weight, mobility, behaviour or energy should not automatically be dismissed as “just ageing.”
• A health checklist works best when it creates a timeline, so changes can be compared with the dog's own normal baseline.

The complete dog health checklist

The exact plan should be agreed with your veterinarian, but these are the major areas worth tracking throughout a dog's life.

Veterinary care

• Routine health examinations
• Vaccination review
• Parasite-risk assessment
• Dental/oral examination
• Appropriate screening tests

Body and nutrition

• Weight
• Body condition
• Muscle condition
• Diet
• Appetite
• Treat intake

Everyday health

• Drinking
• Urination
• Stool
• Vomiting
• Skin and coat
• Eyes
• Ears
• Mouth and teeth

Movement and behaviour

• Exercise tolerance
• Walking/running
• Stairs/jumping
• Sleep
• Behaviour
• Social interaction
• Training/learning

Records

• Vaccinations
• Medication
• Test results
• Diagnoses
• Procedures
• Weight history
• Veterinary recommendations

The value comes from watching how these things change over time.

Why healthy dogs still need health checks

A wellness appointment is not only for giving vaccines.

A dog may appear normal at home while a veterinarian identifies early changes in:

• weight;
• teeth;
• skin;
• heart or lung sounds;
• joints;
• eyes;
• abdomen;
• muscle condition;
• or another body system.

AAHA's current life-stage guidance says preventive veterinary care should continue throughout life, with the content and frequency of visits changing according to the dog's stage and individual needs.

The question is therefore not:

“Is my dog sick enough to go to the vet?”

It is also:

“Are we checking often enough to notice meaningful change early?”

Puppy health checklist

Puppyhood involves rapid growth and development.

AAHA's life-stage framework places particular emphasis at this stage on:

• congenital abnormalities;
• growth;
• preventive care;
• behaviour;
• environment;
• nutrition;
• and early veterinary assessment.

Your puppy checklist should therefore include the following.

1. First veterinary health examination

An early examination allows the veterinary team to establish a baseline and review:

• heart and lungs;
• eyes and ears;
• mouth and teeth;
• abdomen;
• skin and coat;
• joints and movement;
• body condition;
• growth;
• congenital concerns;
• vaccination history;
• parasite prevention;
• identification.

Bring all records from the breeder, rescue or previous caregiver.

2. Puppy vaccination schedule

The principal global core viral vaccines protect against:

• canine distemper;
• canine adenovirus;
• canine parvovirus.

WSAVA's 2024 guidelines recommend beginning these vaccinations at around 6–8 weeks and repeating them at appropriate intervals until at least 16 weeks of age because maternal antibodies can interfere with earlier vaccination.

Other vaccines depend on:

• geography;
• local law;
• lifestyle;
• travel;
• and disease exposure.

Related guide: Puppy Vaccination Schedule: A Complete Guide

3. Parasite prevention

Parasite risk depends substantially on location and lifestyle.

Potential concerns include:

• intestinal worms;
• fleas;
• ticks;
• heartworm;
• and region-specific parasites.

Do not assume one product or timetable is appropriate for every dog internationally.

Ask your veterinarian:

• which parasites are relevant locally;
• what preventive product is appropriate;
• how often testing is recommended;
• and whether travel changes the risk.

This is particularly important for a global 1KAHU audience because parasite exposure differs dramatically by country and region.

4. Growth and weight

Puppies need enough nutrition for healthy growth—but faster or heavier is not automatically better.

Ask your veterinary team to track:

• body weight;
• body condition;
• growth pattern;
• and muscle development.

AAHA's nutrition guidelines recommend assessing weight, body condition score (BCS) and muscle condition score (MCS) as part of regular nutritional evaluation, ideally at veterinary examinations.

For puppies, growth rate can also be particularly relevant in large and giant breeds.

5. Puppy nutrition

Use a nutritionally appropriate diet for growth.

The correct food and feeding amount depend on factors such as:

• size;
• breed;
• growth stage;
• health;
• activity;
• body condition.

Avoid interpreting feeding instructions on packaging as an exact prescription that never needs adjustment.

Your veterinarian can assess whether the puppy's growth and body condition suggest changes are needed.

AAHA considers nutritional assessment a fundamental part of preventive healthcare throughout every life stage.

6. Teeth and mouth

Puppy oral health matters before periodontal disease appears.

As permanent teeth erupt, the veterinary team may check for:

• retained baby teeth;
• missing teeth;
• abnormal eruption;
• crowding;
• malocclusion;
• trauma.

AAHA's dental guidelines specifically recommend examining puppy dentition and addressing persistent deciduous teeth where they create problems.

This is also a good time to begin positive dental-care habits.

7. Socialisation and behaviour

Health is not purely physical.

Puppyhood is an important period for:

• social development;
• confidence;
• learning;
• handling;
• appropriate independence;
• and adaptation to the environment.

Watch for:

• extreme fear;
• persistent withdrawal;
• inability to settle;
• severe resource guarding;
• unusual aggression;
• profound separation distress;
• or other behaviours causing concern.

Do not wait for a behaviour problem to become severe before asking for help.

8. Movement and development

Observe how your puppy:

• walks;
• runs;
• sits;
• rises;
• plays;
• uses stairs where appropriate.

Mention persistent:

• limping;
• unusual gait;
• reluctance to move;
• pain;
• weakness.

Some orthopaedic and developmental problems are easier to investigate when noticed early.

Do not assume unusual movement is simply because the puppy is “clumsy.”

Young adult dog health checklist

As the puppy phase ends, health priorities begin to shift.

AAHA describes young adulthood as the period in which physical and social maturity are completed, with ongoing emphasis on preventive care, behaviour, weight and vaccination.

A healthy young dog still needs active preventive care.

9. Maintain a healthy body condition

Weight problems can begin early.

Do not assess healthy weight purely by:

“My dog weighs 25 kg.”

That number means very little without context.

Veterinary teams use tools such as:

• body weight;
• body condition score;
• muscle condition score.

AAHA recommends evaluating these regularly, ideally at every veterinary examination.

A dog's ideal weight is individual.

10. Watch the waist, ribs and body shape

A commonly used 9-point body condition system considers factors such as:

• whether ribs can be felt;
• visible waist from above;
• abdominal tuck;
• fat deposits.

On the AAHA/WSAVA-style 9-point system, a BCS around 4–5/9 generally represents an ideal range.

Do not try to “diet” a dog based on appearance alone.

If body condition changes, ask your veterinary team to help establish an appropriate goal.

11. Track muscle condition too

Weight can stay stable while muscle is being lost.

This becomes especially important later in life, but establishing the concept early is useful.

Look for changes around areas such as:

• spine;
• hips;
• shoulders;
• skull.

AAHA recommends muscle-condition assessment alongside body condition because the two measure different things.

12. Review diet as life changes

A dog's dietary needs may change with:

• growth;
• neutering status;
• activity;
• working status;
• pregnancy;
• disease;
• age;
• weight.

Avoid assuming the food chosen at 12 months should automatically remain unchanged for the dog's entire life.

Nutrition should be reassessed alongside body condition and health.

13. Dental health should now be part of routine care

Dental disease can develop gradually and may not always cause obvious signs at home.

AAHA reports that periodontal disease is already common in dogs by around three years of age and emphasises dental prevention throughout life.

Watch for:

• bad breath;
• visible tartar;
• red gums;
• bleeding;
• broken teeth;
• difficulty chewing;
• dropping food;
• pawing at the mouth;
• facial swelling.

But absence of these signs does not guarantee the mouth is healthy.

14. Create a home dental-care routine

Your veterinarian may recommend measures such as:

• tooth brushing;
• specific dental products;
• appropriate chews;
• professional dental assessment.

AAHA's dental guidance recommends individualised prevention beginning early and continuing throughout life.

Avoid very hard objects capable of fracturing teeth.

“Natural” does not automatically mean safe for teeth.

15. Keep vaccinations current

Adult dogs do not necessarily need every vaccine every year.

Vaccines have different:

• durations of immunity;
• schedules;
• risk criteria.

WSAVA distinguishes:

• core vaccines;
• non-core vaccines;
• vaccines not recommended.

Its 2024 guidelines emphasise vaccinating dogs appropriately with core vaccines while selecting additional vaccines according to lifestyle and local disease prevalence.

Your veterinarian should document:

what was given → when → why → next review.

16. Review lifestyle risks annually

A dog's life changes.

The dog who never boarded may suddenly begin:

• daycare;
• travelling;
• hiking;
• swimming;
• competing;
• attending training;
• staying in kennels.

That can change risks relating to:

• infectious disease;
• ticks;
• parasites;
• respiratory disease;
• travel documentation.

Preventive care should therefore be reviewed when lifestyle changes.

17. Watch skin and coat

At home, look for changes such as:

• persistent itching;
• redness;
• hair loss;
• scaling;
• lumps;
• sores;
• unusual odour;
• recurrent licking.

Skin problems can have many causes.

Do not assume every itch means food allergy or every lump is harmless.

Record:

where → when noticed → whether changing → photograph if useful.

18. Check the ears

Healthy ears vary in appearance by dog, but changes may include:

• redness;
• discharge;
• strong odour;
• head shaking;
• scratching;
• sensitivity.

Repeated ear problems deserve veterinary investigation rather than endless home cleaning.

Avoid inserting products deep into the ear unless your veterinarian has advised their use.

19. Watch the eyes

Notice:

• redness;
• discharge;
• cloudiness;
• squinting;
• swelling;
• sudden visual changes;
• unequal appearance.

Eye conditions can sometimes deteriorate quickly.

Sudden eye pain or injury warrants prompt veterinary advice.

20. Know your dog's normal appetite

Some dogs are naturally enthusiastic eaters.

Others are less food-focused.

What matters is knowing the individual dog's normal pattern.

Record unexpected changes such as:

• reduced appetite;
• suddenly increased hunger;
• difficulty chewing;
• repeatedly walking away from food.

A change becomes more meaningful when you can compare it with a baseline.

21. Monitor drinking

You do not need to obsessively measure every bowl for a healthy dog.

But be aware of meaningful change.

Ask veterinary advice if your dog begins:

• drinking significantly more;
• drinking significantly less;
• seeking water unusually often.

Increased thirst can occur with many conditions and becomes especially relevant in mature and senior dogs.

22. Monitor urination

Changes worth noting include:

• increased frequency;
• straining;
• accidents in a previously house-trained dog;
• blood;
• unusually large volumes;
• difficulty passing urine.

Difficulty or inability to urinate can be urgent.

Do not wait for a routine appointment if your dog is repeatedly trying and unable to pass urine normally.

23. Monitor stool

Know what is normal for your dog.

Notice:

• diarrhoea;
• constipation;
• blood;
• mucus;
• major changes in frequency;
• persistent change in colour or consistency.

A single mild episode may not indicate serious disease, but repeated or severe changes warrant veterinary assessment—particularly when combined with vomiting, weakness or reduced appetite.

24. Notice vomiting patterns

Dogs occasionally vomit for many different reasons.

What matters is context.

Record:

• how often;
• timing relative to meals;
• what the material looks like;
• whether the dog can keep water down;
• appetite;
• energy;
• abdominal discomfort;
• any possible exposure to unusual substances.

Repeated vomiting, marked weakness, abdominal swelling or inability to keep water down can require urgent care.

Related guide: Dog Vomiting: Common Causes and When to Contact a Vet

25. Track exercise tolerance

Rather than recording only:

“Walked 45 minutes,”

notice:

• pace;
• willingness;
• recovery;
• reluctance;
• limping;
• heavy breathing;
• stiffness afterward.

A change from the dog's own baseline can be more important than the absolute distance.

Mature adult dog health checklist

As dogs move into mature adulthood, preventive care increasingly focuses on maintaining health and identifying change early.

AAHA advises that mature adult dogs generally receive wellness checks once or twice yearly depending on individual needs, with growing attention to screening, weight, muscle condition and mobility.

26. Look for gradual weight change

A slow weight change is easy to miss when you see your dog every day.

Keep a longitudinal record.

For example:

January — 28.2 kg

July — 27.5 kg

January — 25.9 kg

A two-kilogram loss may not be obvious visually.

But on a timeline it becomes difficult to ignore.

Unexplained weight change is one of the nutritional risk factors AAHA says should trigger further assessment.

27. Monitor mobility before obvious limping appears

Joint or musculoskeletal problems do not always begin as dramatic lameness.

Early signs can include:

• slower rising;
• hesitation before jumping;
• reluctance on stairs;
• shorter walks;
• stiffness after rest;
• changed sitting posture;
• difficulty entering the car.

Do not assume these changes are simply laziness or ageing.

They can justify veterinary assessment.

28. Record new lumps and bumps

Dogs commonly develop skin and subcutaneous masses as they age.

Do not diagnose them by appearance or touch alone.

For any new lump, note:

• location;
• approximate size;
• date first noticed;
• change over time.

Photographs beside a ruler can help document growth.

Senior-care guidance warns that some malignant masses can resemble apparently benign growths, so relying only on “watch and see” without veterinary assessment can be risky.

29. Watch behaviour as a health signal

Behaviour change can be medical.

Examples include:

• irritability;
• withdrawal;
• restlessness;
• altered sleep;
• unusual clinginess;
• reluctance to be touched;
• reduced play;
• house-soiling;
• increased vocalisation.

Before assuming:

“My dog has become difficult,”

consider:

“Could something have changed physically?”

Pain, sensory changes and disease can alter behaviour.

30. Review dental health more closely

Periodontal disease risk accumulates over time.

At each veterinary check, discuss:

• home dental care;
• gum health;
• tartar;
• broken teeth;
• need for professional assessment.

AAHA recommends dental health be incorporated into preventive care at every life stage rather than being treated as an occasional cosmetic issue.

31. Discuss screening with your veterinarian

As dogs mature, your veterinarian may recommend screening tests based on:

• age;
• breed;
• previous history;
• medications;
• examination findings;
• disease risks.

Potential tests can include:

• blood work;
• urine testing;
• parasite testing;
• blood pressure;
• imaging where indicated.

There is no universal panel every dog must receive at exactly the same age.

The point is to establish a suitable baseline and look for changes.

When does a dog become senior?

There is no single answer such as:

“Every dog becomes senior at seven.”

Large breeds often age more quickly than small breeds.

Health history matters too.

AAHA's Senior Care Guidelines define the senior stage broadly as approximately the last 25% of the dog's estimated lifespan, rather than using one fixed chronological age.

That means a:

• Great Dane;
• Labrador;
• miniature poodle;
• Chihuahua

may not enter the senior stage at the same age.

Use life stage rather than one universal birthday.

Senior dog health checklist

Senior care is not simply about managing disease.

AAHA specifically emphasises that healthy senior dogs still deserve proactive preventive care, monitoring and screening to preserve quality of life.

32. Increase attention to veterinary monitoring

Senior dogs may benefit from more frequent veterinary care than younger healthy adults.

AAHA's senior guidance recommends medical assessment and screening once or twice yearly for healthy senior animals, depending on the patient.

Individual needs may require even closer follow-up.

The schedule should be determined by your veterinarian.

33. Consider senior screening tests

AAHA's senior-care table recommends, for senior dogs, that a comprehensive blood count, chemistry profile and urinalysis may be performed every 6–12 months, alongside other tests according to risk and clinical judgement.

This is guideline-based North American professional advice, not a universal prescription for every dog in every country.

Your veterinarian may recommend:

• more;
• less;
• or different testing

according to the individual dog.

34. Watch for muscle loss

A senior dog may lose muscle even if the scale barely changes.

Pay attention to:

• hindquarters;
• shoulders;
• spine;
• skull.

Muscle loss can affect:

• strength;
• mobility;
• resilience;
• quality of life.

Body condition and muscle condition should therefore be considered separately.

35. Monitor mobility closely

Senior dogs may develop:

• stiffness;
• arthritis;
• weakness;
• pain;
• neurological problems.

Watch for:

• slower rising;
• difficulty on slippery floors;
• reluctance to climb stairs;
• inability to jump into a vehicle;
• shortening walks;
• slipping;
• changed posture.

Do not dismiss pain as an inevitable part of old age.

AAHA's senior guidance specifically emphasises supporting quality of life and adapting care rather than assuming physical decline is simply unavoidable ageing.

36. Adapt the home when needed

Simple changes may include:

• non-slip rugs;
• ramps;
• softer bedding;
• easier access to water;
• reducing stair use;
• raised or appropriately positioned resources where recommended.

AAHA's senior guidance highlights good traction, padding and environmental adaptation as useful elements of senior-friendly care.

Small environmental changes can preserve independence.

37. Watch appetite more closely

Reduced appetite in an older dog should not automatically be blamed on age.

Potential contributors include:

• dental disease;
• pain;
• gastrointestinal disease;
• kidney disease;
• cancer;
• medication effects;
• other health problems.

AAHA lists reduced appetite and anorexia among possible signs associated with chronic disease in senior pets.

Persistent changes deserve veterinary assessment.

38. Watch thirst and urination

Changes in:

• drinking;
• urine volume;
• frequency;
• house-training

can be important in older dogs.

Diseases affecting the:

• kidneys;
• endocrine system;
• urinary tract;
• liver

may change thirst or urination.

Do not write off new accidents as:

“He's old now.”

Investigate the change.

39. Monitor sleep

Senior dogs may sleep more.

But meaningful changes can include:

• pacing overnight;
• reversed sleep cycle;
• waking repeatedly;
• appearing disoriented;
• vocalising at night.

These can occur for many reasons, including:

• pain;
• urinary needs;
• sensory decline;
• cognitive change.

A video or diary may help your veterinarian understand what is happening.

40. Watch for cognitive and behavioural changes

Possible age-related cognitive changes may include:

• disorientation;
• altered interactions;
• changes in sleep;
• house-soiling;
• altered activity;
• anxiety.

But cognitive dysfunction is a diagnosis that should be made after appropriate veterinary assessment.

Other medical causes can produce similar behaviour.

Do not simply label an older dog “senile” at home.

41. Monitor hearing and vision

Ageing can affect senses.

Watch for:

• startling more easily;
• not responding to familiar sounds;
• bumping into objects;
• hesitation in darkness;
• difficulty locating you.

Sensory loss itself may not always be treatable, but recognising it allows the environment and communication to be adapted.

It may also help distinguish sensory change from apparent disobedience.

42. Continue dental care in senior dogs

Older age is not a reason to ignore dental disease.

Dental pain can significantly affect quality of life.

AAHA's dental guidance describes oral health as a fundamental component of overall wellbeing and notes that significant disease may exist even without obvious outward signs.

Whether a dental procedure is appropriate depends on:

• overall health;
• anaesthetic assessment;
• severity of disease;
• expected benefit.

Age alone should not be used to make that decision.

43. Review nutrition rather than automatically buying “senior food”

There is no single senior diet suitable for every older dog.

The right diet depends on:

• body condition;
• muscle;
• disease;
• activity;
• appetite;
• digestive health.

AAHA's nutrition guidance recommends individual nutritional assessment across all life stages rather than choosing food by age label alone.

A senior dog losing muscle may need a different nutritional approach from an overweight senior with osteoarthritis.

44. Review medication regularly

Older dogs are more likely to take long-term medication.

Keep a current list including:

• drug;
• strength;
• dose;
• frequency;
• reason;
• prescribing veterinarian.

Ask when monitoring tests are needed.

Do not continue an old prescription indefinitely without review simply because it was once appropriate.

45. Keep track of quality of life

Health is more than laboratory values.

Ask:

• Is my dog still enjoying food?
• Do they seek interaction?
• Can they rest comfortably?
• Can they move without major distress?
• Can they toilet comfortably?
• Are there still activities they enjoy?
• Are difficult days becoming more frequent?

Senior care should increasingly consider comfort, function and enjoyment alongside disease management.

AAHA's senior guidelines place quality of life at the centre of care, including for dogs with chronic or progressive disease.

What should you check at home every week?

This does not need to become a medical examination.

A simple awareness check is enough.

Body

• Any new lumps?
• Any wounds?
• Any obvious pain?

Movement

• Walking normally?
• Getting up normally?
• Stairs/jumping unchanged?

Eating and drinking

• Appetite normal?
• Drinking pattern normal?

Toilet

• Urination normal?
• Stool normal?

Skin and coat

• New itching?
• Hair loss?
• Redness?

Eyes and ears

• New discharge?
• Redness?
• Head shaking?

Mouth

• Obvious bad breath?
• Broken tooth?
• Difficulty eating?

Behaviour

• Energy normal?
• Sleep normal?
• Interaction normal?

What matters most is:

Has something changed from normal?

What should you record monthly?

A monthly health snapshot could include:

• weight, if practical and useful;
• body condition;
• medication changes;
• appetite changes;
• mobility;
• recurring symptoms;
• lumps being monitored;
• behaviour changes.

You do not need to measure everything constantly.

The aim is to make gradual trends visible.

What should be updated after every veterinary appointment?

Update:

• visit date;
• reason;
• veterinarian/practice;
• diagnosis or assessment;
• tests;
• medication;
• vaccination;
• weight;
• next review;
• documents.

This is how the pet's medical profile becomes a continuous health history.

Dog health timeline by life stage

Area	Puppy	Young Adult	Mature Adult	Senior
Veterinary care	Frequent early care	Regular preventive care	Once/twice yearly depending on need	Often closer monitoring
Vaccination	Primary series	Maintain appropriate protection	Review lifestyle/risk	Continue individualised plan
Nutrition	Growth-focused	Maintain healthy body condition	Watch metabolism/weight	Protect weight and muscle
Dental	Build habits/check development	Preventive care	Monitor periodontal disease	Maintain comfort and oral health
Behaviour	Socialisation/training	Maintain healthy behaviour	Watch change	Monitor cognitive/behavioural change
Mobility	Development	Activity/fitness	Early stiffness	Mobility, pain, adaptation
Screening	Based on history/clinical need	Individual risk	Increasingly relevant	Often more frequent/structured
Home monitoring	Growth, appetite, stool	Weight, skin, activity	Weight, lumps, mobility	Appetite, thirst, weight, muscle, mobility, behaviour

This is a framework, not a veterinary schedule.

Signs that should prompt veterinary advice

Contact your veterinarian if you notice meaningful or persistent changes such as:

• reduced appetite;
• unexplained weight loss;
• major weight gain;
• increased thirst;
• changed urination;
• repeated vomiting;
• persistent diarrhoea;
• limping;
• difficulty getting up;
• new lump;
• persistent cough;
• behavioural change;
• persistent itching;
• mouth pain;
• altered sleep;
• unusual weakness.

AAHA's senior-care guidance specifically identifies changes such as lethargy, behaviour change, reduced appetite, altered thirst, weight loss and mobility changes as possible signs of chronic disease in older pets.

These signs are not diagnoses.

They are reasons to investigate.

When should you seek emergency veterinary care?

Potential emergencies include signs such as:

• severe difficulty breathing;
• collapse;
• unresponsiveness;
• prolonged or repeated seizures;
• major trauma;
• uncontrolled bleeding;
• sudden severe abdominal swelling;
• inability to urinate;
• profound weakness;
• suspected serious poisoning.

Do not use a routine health checklist to delay emergency care.

This is more useful than displaying dozens of unrelated health fields simultaneously.

The interface should answer:

What matters now?

and then:

How has this dog changed over time?

What should AI Guardian do with this information?

AI can potentially help identify changes in recorded information.

For example:

“Marlene's last four recorded weights show a downward trend.”

or:

“You've recorded three episodes of vomiting this month.”

That is different from saying:

“Marlene has kidney disease.”

The first is:

structured observation.

The second is:

diagnosis.

1KAHU should help guardians recognise patterns and prepare useful information for professionals without presenting automated conclusions as veterinary fact.

Key facts

Health priorities change throughout a dog's life. AAHA's current life-stage guidance distinguishes puppy, young adult, mature adult and senior needs rather than using one preventive-care template forever.

Body condition and muscle condition matter alongside weight. AAHA recommends both as part of routine nutritional assessment.

Dental care should start early and continue throughout life. AAHA considers oral health a standard component of preventive canine care.

Senior is not a fixed birthday. AAHA defines the senior stage broadly as the last 25% of expected lifespan, acknowledging substantial variation among dogs.

Healthy senior dogs still need proactive care. Senior medicine should focus on maintaining quality of life and detecting change, not only treating existing illness.

Senior screening may become more frequent. AAHA's professional guidelines recommend certain laboratory assessments every 6–12 months for senior dogs, although the individual veterinary plan may differ.

Ageing does not explain every change. Appetite, thirst, weight, behaviour and mobility changes can indicate medical problems and should not automatically be dismissed as normal ageing.

Frequently asked questions

How often should my dog have a health check?

Frequency depends on age, breed, health and individual risk. AAHA advises regular preventive care throughout life; mature adult dogs may need wellness visits once or twice yearly, while senior or chronically ill dogs may need closer monitoring.

What should I check regularly on my dog?

Pay attention to appetite, drinking, urination, stool, weight, movement, skin, ears, eyes, mouth, energy and behaviour. The most useful question is whether something has changed from your dog's normal pattern.

How do I know if my dog is a healthy weight?

Veterinarians assess more than kilograms. Body condition score and muscle condition score help determine whether a dog is underweight, ideal, overweight or losing muscle. AAHA recommends these assessments as part of regular veterinary care.

At what age is a dog considered senior?

There is no universal age. AAHA defines the senior stage as approximately the final 25% of expected lifespan, so breed, body size and individual longevity matter.

Do senior dogs need more frequent vet visits?

Often yes. AAHA's senior guidelines recommend proactive assessment and screening once or twice yearly for many healthy senior pets, with frequency adjusted to the individual.

Does my dog need blood tests every year?

Not every dog needs the same schedule. Testing depends on life stage, health and risk. AAHA's senior guidelines recommend CBC, chemistry and urinalysis every 6–12 months for senior dogs as a professional guideline, but your veterinarian should determine what is appropriate for your dog.

How often should I weigh my dog?

There is no single interval for every healthy dog. Weight should be recorded during veterinary visits and more frequently when growth, weight loss, weight management or disease makes monitoring useful.

Should I check my dog for lumps?

Yes. Become familiar with your dog's normal body and mention new or changing masses to your veterinarian. Older dogs in particular may develop masses that cannot reliably be classified by appearance or touch alone.

Is bad breath normal in dogs?

Persistent bad breath can be associated with dental disease and should not automatically be considered normal. Oral health should be reviewed throughout life.

Does every adult dog need yearly vaccination?

Not every vaccine is administered annually. Timing depends on the vaccine, previous history, local rules and individual exposure risk. WSAVA recommends core protection plus appropriate non-core vaccination based on geography and lifestyle.

Is slowing down normal for a senior dog?

Activity can change with age, but reduced mobility may also reflect pain, arthritis or another health problem. Meaningful change deserves veterinary discussion rather than automatically being attributed to age.

Should I change my dog to senior food when they get older?

Not automatically. Nutrition should be based on body condition, muscle condition, health and individual nutritional needs rather than the word “senior” on a label.

What changes in an older dog should concern me?

Persistent changes in appetite, thirst, weight, movement, behaviour, sleep, urination or energy are worth discussing with a veterinarian. AAHA identifies many of these as potential signs of chronic disease in senior animals.

Healthy ageing starts long before a dog becomes old

A dog-health checklist is not something you begin when grey hairs appear around the muzzle.

The health history starts with:

the first puppy examination.

Then:

vaccination.

growth.

nutrition.

weight.

dental care.

behaviour.

exercise.

preventive visits.

Over time, those individual moments become a baseline.

And that baseline makes change easier to recognise.

The dog who has always weighed 24 kg is now 21.5 kg.

The dog who climbed stairs easily now pauses before the first step.

The dog who slept through the night now wanders at 3 a.m.

The dog who loved dinner now leaves half the bowl.

Those are not diagnoses.

They are signals worth noticing.

The goal is not to monitor your dog anxiously every day.

It is to know them well enough that meaningful change does not disappear into the background.

From puppyhood to the senior years, preventive care is fundamentally about the same thing:

protecting health today while paying attention to what is changing tomorrow.

One health history, from the first puppy check to the senior years.

A dog's care can span more than a decade.

1KAHU is designed to keep that history connected within the same profile:

Veterinary Visits

Vaccinations

Medication

Weight

Dental Care

Test Results

Health Documents

Professionals

Reminders

Instead of health information being replaced every time the dog reaches another life stage, the profile grows with them.

That means a guardian—and, when permission is given, the professionals caring for the dog—can understand not simply:

“What is happening today?”

but:

“What has changed over time?”

One Guardian. For All Pets.
