Your Pet's Health Timeline: What to Track at Every Life Stage

By Dr Duncan Houston

A useful pet health record does not need to be elaborate. Knowing your pet's usual weight, appetite, movement and toileting pattern gives you and your vet a better starting point when something changes.

Quick Answer

Keep a dated record of veterinary visits, vaccines, parasite prevention, medications and meaningful changes in everyday behaviour. Puppies and kittens need several early visits, healthy adults need regular preventive reviews, and older or unwell pets often need more frequent assessment. Exact schedules depend on species, size, health, local disease risk and the products used.

A practical timeline

AAHA's dog life-stage guidance supports tailoring visit frequency as needs change. A common starting point is an annual adult review and twice-yearly senior reviews, with additional visits when indicated. A scheduled checkup is never a reason to postpone a new concern.

“Senior” is not a universal seventh birthday. Dogs age differently according to size and individual health; feline life-stage guidelines classify cats over ten years as senior.

Record preventive care accurately

Write down the actual vaccine or medication, administration date and next due date supplied by your clinic. Do not assume all vaccines last three years or that all parasite products are monthly. The AAHA vaccination guidelines distinguish schedules by vaccine and individual circumstances. Local requirements and exposure matter too.

Record your pet's current weight, the product strength and prescribed instructions for medications. If a dose is missed, contact the clinic or follow the authorised product instructions rather than doubling it. Keep previous results and discharge notes accessible, especially when travelling or changing clinics.

Track trends without turning every day into a test

• Weight and body condition: use the same scale where practical and ask your vet how often to weigh. Growth, weight-loss plans and chronic disease need closer monitoring.
• Food and water: note meaningful changes, including slower chewing or consistently unfinished meals.
• Toileting: changes in frequency, effort, urine volume or stool quality can be useful clues.
• Comfort and behaviour: record new hesitation, hiding, irritability or disrupted sleep.
• Photos and videos: date images of a lump or coat change and capture natural movement when safe.

Increased drinking can have several medical causes; reduced activity can reflect pain, illness or environmental changes. A log helps describe the pattern but cannot identify the diagnosis. Dental disease also needs examination, not just photographs or a fixed cleaning calendar.

When not to wait

Seek emergency care for difficulty breathing, collapse, severe distress, suspected poisoning, a swollen abdomen with unproductive retching, or attempts to urinate without passing urine. Contact your vet promptly for repeated vomiting, marked weakness, rapidly worsening symptoms or a cat that stops eating. Cornell's guidance on feline appetite loss explains why prolonged fasting is dangerous.

Do not wait to complete a chart, obtain a wearable reading or reach a generic 24-hour threshold. Young and medically vulnerable pets may need help sooner.

Common mistakes and other species

Avoid using reminders as proof that treatment was given, changing several treatments at once without advice, or assuming normal tracker readings rule out illness. Review the record with everyone responsible for care.

Rabbits, birds, reptiles, horses and farm animals need species-specific plans. Record diet, housing, reproduction and group illness where relevant, but do not transfer dog-and-cat vaccine or deworming schedules to them. Your veterinary team can set an appropriate individual or herd-health programme.

Frequently asked questions

Do I need an app?

No. A notebook, spreadsheet or existing digital record can work if it is accurate and easy to share.

Should every senior pet have the same blood tests?

No. Your vet selects tests using age, symptoms, examination findings, previous results and treatment needs.

What should I bring to an appointment?

A concise timeline, medication list, diet details, previous results and relevant videos are helpful.

Can tracking prevent emergencies?

It may help you notice changes and organise care, but it cannot prevent or predict every illness.

Focus on a few reliable observations and a care schedule that fits your pet. Consistency is more useful than a complicated record you cannot maintain.
