Dog Weight Loss Plan: Safe Slimming Guide
Vet-reviewed via PetHealth+ · Last reviewed June 2026
Weight loss should be gradual and vet-supervised — aim for 1–2% body weight loss per week. Cut treats, measure meals, and increase exercise appropriately for your dog's joints and age.
Body condition score
You should feel ribs with a light cover — if not, your dog may be overweight.
Measuring food
Use a kitchen scale, not a scoop alone.
Exercise
Start with low-impact walks and build up; swimming is excellent for heavy dogs.

Frequently asked questions
How do I know if my dog is overweight?
Ribs hard to feel, no waist visible from above, and a sagging belly suggest excess weight.
Can I use a human diet for my dog?
No — dogs need balanced canine nutrition; crash diets are dangerous.
Are weight-loss dog foods worth it?
Prescription or light diets can help under vet guidance.
How long until I see results?
Most owners notice changes within 4–8 weeks of consistent portion control.
