Is my dog overweight? Check with a photo

The clearest way to tell is body condition, not the number on the scale: feel for the ribs and look for a waist. On the 9-point body condition score, 4–5 is ideal and 6+ is overweight. It matters — an estimated 59% of US dogs are overweight or obese, yet only about 39% of owners recognize it (APOP, 2022).

Signs your dog may be overweight

  • You can’t easily feel the ribs when you run your hands along the sides
  • No visible waist when you look down from above
  • The belly hangs level or sags instead of tucking up
  • Getting tired on walks, or reluctance to move and play
  • A rounded or broadening back and fat pads over the hips

What to do next

If your dog looks like a 6 or higher, a gentle, vet-guided calorie reduction is the fix. Work out the daily calories for weight loss with the dog calorie calculator, and see exactly how the targets are worked out on the methodology page. Confirm any weight-loss plan with your veterinarian.

A photo estimate is a helpful screening tool, not a diagnosis. Sudden weight change, a distended belly, or any health concern warrants a veterinary exam.
