Is my dog overweight?

Use three checks. Ribs: you should feel them easily under a thin layer of fat, without pressing hard. From above: there should be a visible waist behind the ribs. From the side: the belly should tuck up rather than run straight or sag. Failing all three usually means overweight.

Why the scale isn't the answer

Breed and frame vary so much that a number in pounds tells you little on its own. Body condition — what you can feel and see — is what vets actually assess, and it's something you can do at home in under a minute.

Weight matters most as a trend. The same dog gaining steadily over six months is more informative than any single reading.

Why it matters more than it looks

Excess weight shortens life and accelerates joint disease, and it's one of the most common and most reversible problems in pet health. It also makes existing conditions like arthritis considerably more painful.

The good news is that body condition responds well to modest changes — measured portions rather than free feeding, fewer treats, and consistent daily walks.

When weight loss is the worry instead

Unexplained weight loss is more concerning than gain, particularly in older dogs. If your dog is losing condition without a change in food or exercise, that's a vet conversation rather than a diet win.

Common questions

How do I know if my dog is overweight without scales?

Feel for the ribs, look for a waist from above, and check for a belly tuck from the side. Those three checks are what vets use.

How much should I feed my dog to lose weight?

Don't guess — ask your vet for a target. Rapid restriction is unsafe, and the right amount depends on their ideal weight rather than their current one.

Is a dog's belly supposed to hang down?

No. From the side, the abdomen should tuck upward behind the ribcage.
