Overweight dog — health risks and what to do

Overweight dogs face shorter lives and higher disease risk — book a weight check with the vet nurse for a structured plan.

Dog

In the next 60 seconds

  1. Vet weight check and body condition score.
  2. Bloods to rule out underlying disease.
  3. Structured calorie-controlled plan.

Recognise the signs

  • Cannot easily feel ribs
  • No visible waist
  • Pot belly
  • Reduced exercise tolerance
  • Reluctance to exercise

First aid steps

  1. Vet weight check and body condition score.
  2. Bloods to rule out underlying disease.
  3. Structured calorie-controlled plan.

Do NOT

  • Do not crash-diet.
  • Do not feed human leftovers.
  • Do not assume slow weight loss isn't working — 1-2% per week is healthy.

When to phone the vet immediately

  • Suspected underlying disease
  • Severe obesity affecting mobility

Checking your dog's body condition at home

Run your hands over your dog's sides, back, tail base, and underside, then look at them from the side and from above.

  • Ribs: in a healthy weight, you should feel them with light pressure, and the skin should move freely over them.
  • Waist: should be visible from both the side and from above. If it isn't visible from either angle, that's a sign your dog may be overweight.
  • Belly: should tuck up rather than sagging or bulging outward.
  • Tail base: a build-up of fat here is an overweight sign — on a healthy dog there shouldn't be any.
  • Spine and hips: you should be able to feel them under the skin but not see them.

Common causes

  • Overfeeding, excess treats
  • Reduced exercise
  • Neutering without diet adjustment
  • Underlying disease (rare — Cushing's, hypothyroidism)

Frequently asked questions

How long does weight loss take?

Typically 6-12 months for a structured plan. Slow and steady protects muscle.

Can my dog have treats?

Yes — within calorie allowance. Vegetable treats (carrot, broccoli) are low-calorie alternatives.

How can I tell if my dog is overweight without a vet visit?

Run your hands over their sides — you should feel the ribs with light pressure. Look from above and the side — a waist should be visible from both angles, and the belly should tuck up rather than bulge out. If the waist isn't visible or there's a fat pad at the tail base, that points to overweight.

Will exercise alone do it?

Diet matters more than exercise for weight loss. Both together work best.
