Adult Dog & Cat Breed Weight Reference Chart
Look up typical adult weight ranges by dog and cat breed, from toy breeds to giants, to sanity-check a patient or pet against breed norms. Individual animals vary - use this as a sanity-check, not a diagnosis.
Individual dogs and cats vary.
Use these ranges as a sanity-check, not a diagnosis. Frame size, body condition, and sex all shift a healthy weight within (and sometimes outside) the typical range.

How to use this tool
Why dogs vary so much more than cats
Dogs have the widest weight range of any single domesticated species - from ~1.5 kg toy breeds to ~90 kg giants - a result of intensive selective breeding for different working purposes. Cats have been under much less size-based selection pressure, so breed-to-breed variation is comparatively small.
Tracking a growing puppy
A single weight check against the breed's adult range is less useful than plotting your puppy's own growth curve over time. Pair this chart with the site's pet age calculator for life-stage context, and talk to your vet if growth seems to be stalling or accelerating abnormally.
Weight range position isn't everything
Being at the top of a breed's range isn't necessarily a problem. Frame size, body condition score, and muscle-vs-fat distribution matter more than raw weight - see the site's body condition score tool for a fuller picture.
Frequently asked questions
Why is there such huge weight variation between dog breeds compared to cats?
Dogs have the widest weight range of any single domesticated species - from ~1.5 kg toy breeds to ~90 kg giant breeds - due to intensive selective breeding for different working purposes. Cats have been under much less size-based selection pressure, so breed-to-breed variation is comparatively small.
How do I know if my puppy is growing on track?
Compare against the breed's typical adult range, but more usefully, plot your puppy's own growth curve over time alongside this site's pet age calculator for life-stage context, rather than relying on a single weight check. Talk to your vet if growth seems to be stalling or accelerating abnormally.
Is being at the top of a breed's weight range a problem?
Not necessarily. Frame size, body condition score, and muscle-vs-fat distribution matter more than raw weight - a lean dog at the top of the range is very different from an overweight dog at the bottom. Use this site's body condition score tool alongside this chart.
