Dog health: topic directory and resources

Find a topic, prepare your questions and get the right veterinary support.

Our clinical guides require veterinary review. Until that review is complete, the links below take you to established veterinary-charity resources. They are clearly labelled external sources. This directory does not diagnose your dog or recommend a treatment.

Keep useful notes for your appointment

Write down what changed, when it began, your dog’s usual food and portions, and any medicines or supplements. Bring the exact product labels. These notes help your veterinary team understand the situation; they are not a way to diagnose a condition yourself.

Where nutrition fits

Our label guide and comparison tools organise declared food information. They do not establish whether an ordinary food can be used for a dog with a medical condition. A prescribed diet, suspected allergy or unexplained change in weight or appetite should be discussed with your vet before using product comparisons to change food.

Our review standard

Clinical drafts must show their sources, evidence-check date, important limitations and a verified veterinary reviewer before publication. A disclaimer is not a replacement for review. We do not publish automated treatment plans, human-to-dog medicine conversions or diagnostic quizzes.
