What should I record about my dog's appetite changes before discussing them with the vet?

Published October 26, 2026

The short answer

Record how much your dog actually eats each day — meals offered, amount left, treats and chews included — and whether she approaches food eagerly then walks away, refuses entirely, or eats but more slowly than usual. Note when the change started, whether water intake, weight, energy, stools, or vomiting changed with it, and any new food, medication, or household disruption in the same window. Keeping that daily appetite record in KinsLe's Pet Passport gives your vet measured facts to work from instead of a general impression that she is eating less.

Measure Amounts Instead of Impressions

'She is eating less' becomes far more useful when it is measured, so for the days before the appointment record what was offered and what was actually eaten at each meal, in the units you really use — cups, tins, pouches, or handfuls — plus every treat, chew, and training reward, which can quietly add up to a meal for a small dog. Note whether she leaves the same portion each time, picks out favorite pieces and leaves the rest, or stops mid-meal. If you feed alongside other pets, note whether you are certain what she ate, because a bowl topped up in a multi-dog kitchen can hide one dog's falling intake for weeks. Weighing her at home, or noting how her ribs and waist feel compared with last month, turns a vague worry into a trend the vet can act on.

Describe How She Approaches the Food

How a dog eats tells a story separate from how much. Record whether she comes to the bowl eagerly and then turns away, sniffs and leaves without starting, eats slowly or drops pieces, chews on one side, or seems hungry and begs but then refuses her own meal. Note whether she will accept favorite foods while refusing her usual diet, because a dog who rejects everything is a different case from a dog holding out for something better. Record drooling, lip-licking, grass-eating, or gulping around mealtimes, and whether meals are followed by vomiting, retching, or discomfort. Note, too, whether the change is constant or varies — worse in the morning, worse after exercise, fine on some days — since that rhythm is information a vet will ask about and most owners have not consciously tracked.

Track What Changed at the Same Time

Appetite rarely shifts in a vacuum, so record the surrounding picture for the same days: water intake up, down, or unchanged; stools firmer, looser, or less frequent; energy and interest in walks; sleep; and any vomiting or weight change you can detect. List anything new in the same window — a different food or a freshly opened bag, a new medication or supplement, a recent vaccination, visitors, building work, a house move, a lost companion animal, or even a change in who feeds her and where the bowl sits. Dogs in multi-pet homes sometimes eat less because a housemate has begun guarding the feeding area, which no blood test will reveal but a few days of watching will. Honest context like this can save a long and expensive search in the wrong direction.

Know When Appetite Loss Cannot Wait for the Appointment

Some appetite changes should not wait for a routine discussion. A dog who refuses all food and water, vomits repeatedly, seems painful, has a swollen abdomen, collapses, or is a puppy, very old, or managing an ongoing condition should be seen promptly rather than logged for later. Complete refusal lasting beyond roughly a day in an otherwise healthy adult dog also deserves a call rather than continued watching, and sooner if anything else is off alongside it. When you do talk to the vet, hand over the record itself rather than a summary, and ask what pattern they see in it. Filing that dated appetite log in KinsLe's Pet Passport keeps the amounts, behavior notes, and vet feedback in her health record, ready if the change returns or another clinic needs the history.
