No clinical assessment

The website cannot examine your pet and does not recommend medicines, supplements, therapeutic diets or treatment plans.

Individual variation

Actual needs may differ because of age, breed, body composition, environment, health and other factors. Monitor weight and body condition over time.

When to contact a vet

Speak with a qualified veterinarian for puppies or kittens with unusual growth, pregnant or nursing pets, significant weight change, illness, therapeutic diets, persistent appetite changes, vomiting, diarrhoea or other health concerns.
