Dog & Cat Health • Weight

Is my dog or cat overweight?

Body weight alone does not tell the whole story. Veterinarians combine weight with body condition score and muscle condition to judge whether a pet is carrying excess fat or losing lean tissue.

Quick check

At an ideal body condition, ribs should usually be easy to feel with a light fat covering, with a visible waist from above and abdominal tuck from the side. Breed and body type still matter.

What is body condition score?

Body condition scoring uses visual and hands-on landmarks to estimate body fat. A 9-point system is commonly used. A score around 4–5/9 is generally considered ideal for many adult dogs and cats, although the individual animal matters.

Why excess weight matters

Excess body fat can worsen mobility, osteoarthritis, respiratory stress and metabolic health and can make examination or anesthesia more challenging. Weight control is therefore a health intervention, not a cosmetic goal.

Why muscle condition matters too

A pet can be overweight and still have muscle loss, especially in senior or chronically ill animals. Muscle condition should be assessed separately from body fat so that weight loss does not come at the expense of lean tissue.

How should weight loss be approached?

Start with an accurate diet history: measured meals, treats, table food, chews and food used for medications all count. A veterinarian can set a target weight or body condition and select an appropriate calorie intake while checking for medical problems that may affect weight.

Avoid crash dieting. Rapid restriction can be unsafe, especially in cats. Planned, monitored weight reduction is preferred.
