Is your dog or cat at a healthy weight? Choose your pet’s breed, age and weight, then pick the body shape that matches. You’ll see where your pet sits from “too thin” to “obese”, an estimated ideal weight, the typical adult weight range for the breed, and daily calorie needs. In India, extra rotis, biscuits, ghee and treats are common reasons pets gain weight.

Step 1: your pet · Step 2: body shape · Step 3: results
Which best describes your pet’s body? (feel the ribs, look for a waist from above and a tummy tuck from the side)
Estimates for healthy pets only. Breed ranges are typical adult weights from breed standards (males are usually heavier than females); body shape is a better guide than breed charts. Plan any weight change with your vet.
How to score your pet’s body condition
Vets use a 9-point body condition score (BCS) instead of weight alone, because a healthy weight differs between breeds and individuals. Check three things with your pet standing:
- Ribs: run your flat hands along the chest. At ideal weight, you can feel the ribs easily under a thin fat layer, like the back of your hand.
- Waist: look from above. There should be a visible waist behind the ribs.
- Belly tuck: look from the side. The belly should tuck up behind the ribs (in cats, a small fat pad under the belly is normal).
| Score | Description |
|---|---|
| 1 | Emaciated: ribs, spine and hip bones visible from a distance; no body fat; obvious muscle loss |
| 2 | Very thin: ribs, spine and hip bones easily visible; no fat felt; some muscle loss |
| 3 | Thin: ribs easily felt and may be visible, no fat cover; top of spine visible; obvious waist and tuck |
| 4 | Slightly lean: ribs easily felt with minimal fat; waist easily seen from above; belly tucked up |
| 5 | Ideal: ribs felt without excess fat covering; waist seen behind the ribs from above; belly tucked up from the side |
| 6 | Slightly overweight: ribs felt with slight excess fat; waist visible but not prominent |
| 7 | Overweight: ribs felt with difficulty under heavy fat; fat over lower back and tail base; waist barely visible |
| 8 | Obese: ribs not felt or only with firm pressure; heavy fat over spine and tail base; no waist; belly may sag |
| 9 | Severely obese: massive fat over chest, spine, tail base; no waist; obvious belly distension |
Scores of 4–5 are ideal. Each point above 5 means roughly 10% extra body weight, so a dog with BCS 7 is about 20% overweight.
Typical adult weights by breed
These are typical adult weight ranges from breed standards and veterinary references. Males are usually at the upper end and females at the lower end. A dog or cat can be outside the range and still healthy, or inside it and still overweight, which is why body condition matters more.

Why a healthy weight matters
- In a lifelong study of Labrador Retrievers, dogs kept lean lived about 2 years longer and developed arthritis later than their overweight littermates.
- Excess weight increases the risk of osteoarthritis, cruciate ligament injury, diabetes (especially in cats), breathing problems and heat stroke in flat-faced breeds, skin-fold infections, and complications during anaesthesia.
- In cats, obesity is the main risk factor for diabetes and also raises the risk of urinary disease and liver problems (hepatic lipidosis) if they stop eating.
Safe weight-loss plan
- Confirm with your vet that there is no medical cause (for example hypothyroidism or Cushing’s disease in dogs). See diabetes and Cushing’s.
- Measure food with a kitchen scale, not a cup, and feed based on ideal weight calories.
- For significant weight loss, a veterinary weight-loss diet keeps protein, vitamins and minerals adequate while cutting calories. Simply feeding less of a normal food can cause deficiencies.
- Count treats: keep them under 10% of daily calories. Replace biscuits and roti pieces with small pieces of carrot, cucumber or apple (no seeds).
- Stop table scraps, ghee and sweets entirely.
- Increase activity gradually: brisk walks in cool hours for dogs; play sessions with wand toys for cats; food puzzles.
- Weigh every 2 weeks. Aim for 1–2% loss per week in dogs and 0.5–1% in cats. Never starve a cat: rapid weight loss can cause fatal liver disease.
Frequently asked questions
How accurate is this calculator?
It gives a reasonable starting estimate for healthy adult pets. Individual needs vary by breed, age, activity and metabolism by up to 20–30%, so adjust food based on regular weigh-ins and your vet’s advice.
My dog is always hungry. How can I reduce food?
Use high-fibre, high-protein weight-loss diets, split food into 3–4 meals, use slow feeders and food puzzles, and give low-calorie vegetable treats. Persistent extreme hunger can be medical; tell your vet.
Why is my pet losing weight without dieting?
Unexplained weight loss can be caused by worms, tick fever, dental pain, kidney disease, diabetes, hyperthyroidism in cats, cancer and other illnesses. See a vet.
Can I use this for puppies or kittens?
No. Growing animals have very different needs. Use the feeding guide on a complete puppy or kitten food and track growth with your vet.
