How to prepare information for a vet visit

Much of what a veterinarian needs can only come from you. Merck's owner-facing material on detecting kidney and urinary problems in dogs and cats describes the history a veterinarian gathers from an owner: changes in how much the pet drinks, how often they urinate, how much urine they produce, how the urine looks, and how the pet behaves — together with appetite and diet, changes in body weight, and previous illnesses or injuries.

That is a specific, answerable list, and it is worth noticing how much of it is longitudinal. Almost every item is a change rather than a state — which is exactly the kind of thing that is hard to recall accurately under pressure with an anxious animal on the table.

Work through this the day before, or the morning of. It takes a few minutes. The underlying detail of what veterinarians ask owners is sourced below; the order below is just a workable way to gather it.

1. Write the one-line reason for the visit

One sentence, in your own words, on why you booked. If it is a routine check with a small worry attached, say both — the small worry is often the part that gets forgotten.

2. Build the timeline

• When did it start, as precisely as you can manage?
• Is it constant or intermittent? At particular times, or after particular things?
• Is it stable, improving or worsening?
• What else changed around the same time — food, household, routine, medication?

3. Gather the everyday numbers

• What your pet eats, including treats, and any recent diet change
• Roughly how much they are drinking, and whether that has changed
• Urination and defecation — frequency, appearance, any straining
• Current weight if you have it, and the trend over recent weeks
• Activity level and mobility

4. List medications, supplements and known conditions

Names and doses if you have them, including anything given occasionally or recently finished. Bring the packaging if you are unsure — a photograph of the label works. Note any known conditions and any relevant past illness or injury.

5. Collect any photos or video

Useful for anything visible or intermittent that may not happen during the appointment — a gait change, a skin change, a cough, unusual breathing. Date them if your phone does not.

6. Write down your questions

Three or four, in priority order. Appointments run short and the questions you actually care about are the first casualties. Ask the most important one first rather than saving it for the end.

7. Decide who is going

Where possible, the person who has actually observed the change should be the one in the room, or should write their observations down for whoever is. Second-hand history loses exactly the detail that matters.

Preparation is for a visit you have time to plan. Some situations are not that. The Merck Veterinary Manual lists signs warranting immediate veterinary attention, including difficulty breathing, seizures, heavy bleeding, straining but failing to urinate or defecate, severe or constant pain, and staggering or other problems walking.

Worth doing, and a separate job from this page. Getting a cat into a carrier or a nervous dog through a waiting room affects how the appointment goes, and it is easier to plan for in advance than to improvise on the day.

AAHA publishes owner-facing guidance on preparing your pet for a successful veterinary visit, covering before, during and after the appointment for both dogs and cats. It is the better source for that side of the visit than anything we would add here.

• What to track when your pet seems different — how to build the record this checklist draws on.
• Pet weight and body condition — what the weight figure does and does not tell you.
• Pet appetite changes — what to gather before an appointment about eating.
• Pet water intake changes — what to gather before an appointment about drinking.
