How can you tell the difference between fluff and fat? It’s not always as easy as it looks, unless you know exactly what to look for. The World Small Animal Veterinary Association and the Alberta Ministry of Agriculture and Forestry have developed these diagrams to help pet and horse owners evaluate the health of their animals. These diagrams serve as a relative reference only and should not be taken as an indication of your animal’s overall health. If you have any concerns about your animal’s weight or health, consult with your veterinarian for a comprehensive and reliable evaluation.
