The question "how much should my dog weigh" has no single answer — it all depends on breed, sex and build. The ideal weight is not a number from the internet, but a state in which the dog is fit, has palpable ribs and a noticeable waist. Even so, knowing the typical weight ranges for a breed gives a good point of reference.
Typical weight ranges of popular breeds
- Chihuahua: 1.5–3 kg
- Jack Russell Terrier: 5–8 kg
- Border Collie: 14–20 kg
- Labrador Retriever: 25–36 kg
- German Shepherd: 22–40 kg
- Saint Bernard: 60–90 kg
These are reference values for adult dogs. Bitches usually weigh less than males of the same breed, and differences within breeding lines can be considerable.
The Body Condition Score (BCS) scale
Veterinarians use the BCS (Body Condition Score) scale, usually ranging from 1 to 9, where 4–5 means an ideal weight:
- 1–3 — underweight: ribs, spine and pelvis clearly visible
- 4–5 — ideal weight: ribs palpable, waist visible from above, belly tucked up from the side
- 6–7 — overweight: ribs hard to feel, the waist disappears
- 8–9 — obesity: a thick layer of fat, no waist, fat deposits on the limbs
How to assess a dog's condition at home — step by step
- Place your hands on the dog's chest and press gently — the ribs should be palpable without firm pressure
- Look at the dog from above — a waist should be visible behind the ribs
- Look from the side — the belly should be tucked up, that is, raised toward the rear
- If you cannot feel the ribs and the waist has disappeared, the dog is probably overweight
Why weight matters
Excess weight shortens a dog's life, strains the joints and heart, and increases the risk of diabetes. Being underweight, in turn, signals malnutrition or illness. Regular weighing and BCS assessment let you react before the problem develops.
Note: the weight ranges are approximate and do not account for individual build. This is not veterinary advice — if you suspect over- or underweight, consult a veterinarian.
