Dog Ideal Weight Calculator by Breed
Check if your dog is at a healthy weight for their breed, with a plain-language assessment.
Results are estimates only — not a substitute for veterinary advice.
How the ideal weight calculator works
Each breed has a well-documented healthy weight range published by kennel clubs and veterinary associations. Our database covers 50+ popular breeds. If your dog is a mixed breed or an uncommon pure breed, select the appropriate size category (toy, small, medium, large, or giant) for a range-based estimate.
The calculator compares your dog's current weight to the minimum and maximum of their breed's healthy range and gives you a plain-language assessment: healthy, underweight, or overweight — along with how far they are from the range in kilograms.
Limitations: Breed weight ranges are population averages. Individual dogs can be healthy at the edges of or slightly outside these ranges depending on their frame size, muscle mass, and sex. The best assessment tool is your vet's body condition score (BCS), which evaluates rib feel, waist definition, and abdominal tuck.
Frequently Asked Questions
The most reliable at-home check is the rib test: you should be able to feel your dog's ribs with gentle pressure but not see them easily. Our calculator compares your dog's current weight to the breed's healthy range—but the gold standard is your vet's body condition score (BCS), which is a 9-point scale.
The ideal weight for a Labrador Retriever is typically 25–36 kg (55–80 lb), with females toward the lower end and males toward the upper. Individual variation is normal. Our calculator uses this range and tells you how far your dog's current weight falls from it.
Even 10–15% above ideal weight is considered overweight, and 20% or more is obese. Excess weight in dogs is linked to joint disease, diabetes, heart disease, and a shorter lifespan. If your dog is more than 1–2 kg above the healthy range, a vet-guided diet plan is a good idea.
For mixed breeds, the healthy weight range depends on size category. Our calculator offers 'Mixed / Unknown' options by size (toy, small, medium, large, giant) with appropriate ranges for each. If you know the primary breed mix, choosing that breed will give a more accurate result.
Yes, especially in long-coated breeds where a thick coat can mask visible ribs and spine. The rib-feel test is more reliable than visual inspection. Underweight dogs may show low energy, poor coat quality, or muscle wasting. Causes include parasites, dental pain, or underlying illness—always check with your vet.
