Food history is an important part of a digestive evaluation. The most useful record includes the main diet, exact amounts, treats, chews, supplements, table food, access to other pets’ food, and every recent change.
Why the complete diet history matters
A label such as “chicken food” or “sensitive stomach diet” may leave out details your veterinarian needs. Record the brand, product line, flavor, form, amount, feeding times, how portions are measured, and who feeds the dog. Include anything given to hide medication.
The WSAVA nutrition guidance emphasizes that nutrition should be tailored to the individual animal. Appearance or marketing language alone does not determine whether a food is appropriate.
Food transitions and digestive changes
A rapid switch can coincide with loose stool, gas, or appetite changes in some dogs. For many dogs, changing foods gradually over about 7 to 10 days may reduce gastrointestinal upset. Ask your veterinarian for a transition plan that fits your dog, especially if your dog has ongoing disease, a prescribed therapeutic diet, or current digestive symptoms.
When a change occurs, note the old and new products, transition dates, proportions, portions, and symptoms. Link the record to the broader digestive changes timeline.

Treats, chews, scraps, and scavenging
Small extras can add up. UC Davis and WSAVA guidance recommends that treats and other additional foods generally make up no more than about 10% of a dog’s daily calories, with the remaining calories coming from a complete and balanced diet. Individual needs differ, and some dogs need stricter limits or specific treats.
- Record each treat and chew, including training rewards.
- Include table food and foods used for medication.
- Note access to trash, compost, outdoor food, or other pets’ bowls.
- Tell your veterinarian about vitamins, oils, probiotics, and other supplements.
Do not diagnose a food problem from stool alone
Digestive signs can have many causes. Even when food-responsive disease is possible, a veterinary diet trial needs a clear plan and careful adherence. Changing ingredients repeatedly or removing foods without a structured plan cannot confirm a food intolerance or allergy. Unsupervised restriction can create nutritional gaps, obscure the history, or delay assessment of another problem.
UC Davis notes that gastrointestinal nutrition strategies may differ in digestibility, fat, fiber, and protein source, and the best approach varies by patient. Work with your veterinary team rather than cycling through foods at random.
Track patterns without overinterpreting them
Log meals and stool observations with the same time reference. Look for repeated timing, not a single coincidence. A digestive change that follows a food change is useful context, but timing alone does not prove that the food caused it. The digestive pattern tracking guide explains how to compare observations over weeks while leaving interpretation to your veterinarian.
Questions to bring to your veterinarian
- Is the current diet complete and appropriate for my dog’s life stage and conditions?
- How quickly should a food transition happen?
- Which treats and chews fit the plan?
- Would a structured diet trial be useful, and what counts as a deviation?
- Which symptoms mean I should stop monitoring and call?
