What is the average weight of a dog?

There isn't a meaningful average — the range across breeds is too vast (from 1.5 kg to over 90 kg). A better question is: what is the healthy weight range for my dog's specific breed and sex? The breed guides on this site and the Weight Checker provide breed-specific ranges.

How do I know if my dog is overweight for their breed?

Compare your dog's current weight to the breed-appropriate range for their sex, then confirm with a body condition check. At an ideal weight, you should be able to feel (but not see) the ribs with light pressure, see a waist from above, and see a slight belly tuck from the side. If ribs are hard to find and the waist has disappeared, the dog is likely overweight regardless of where the number falls in the breed range.

Do male and female dogs weigh the same within a breed?

No — males are consistently heavier than females in most breeds, often by 15–30%. Many AKC breed standards list separate weight ranges for males and females. When looking up an ideal weight, always check the sex-specific range rather than applying a single number.

My mixed-breed dog — what weight range applies?

For mixed-breed dogs, breed-specific standards don't apply cleanly. The most useful tools are a body condition score (which is breed-agnostic) and a comparison to the size category that matches your dog's overall build. If your dog has been DNA tested and you know the primary breeds, those breed standards can provide a rough reference.

At what age do dogs reach their adult weight?

It depends on breed size. Toy and small breeds typically reach adult weight by 9–12 months. Medium breeds by around 12–15 months. Large breeds by approximately 15–18 months. Giant breeds can continue filling out until 18–24 months or later. A dog is generally considered 'adult' for feeding purposes once they've reached their breed's typical adult size.
