How this dog weight chart estimate works

We assume a typical growth pattern for each size class and use a percentage of expected adult weight at a given age:

At ~3 months, many puppies are ≈ 35–40% of adult weight.
At ~6 months, ≈ 60–70% of adult weight.
At ~12 months, ≈ 90–100% of adult weight (giant breeds may continue growing).

We then build a reasonable ±15% “healthy band” around this estimate. Individual breeds vary widely, so always confirm with your vet and monitor body condition score (BCS).

Why Dog Weight Matters

Keeping your dog near an ideal weight helps protect joints, heart health, and lifespan. Underweight dogs may have underlying illness or inadequate nutrition; overweight dogs are at higher risk for arthritis, diabetes, and many other conditions.
