Dog Weight Calculator

Estimate adult dog weight from puppy age and breed.

How It Works

  1. Enter puppy info. Add current age (weeks) and weight (lbs) in the main fields.
  2. Quick estimate. The result uses a simple ×2.5 rule for a fast adult weight projection.
  3. Select breed. Choose a breed for typical adult range and sex-based adjustments.
  4. Refine with parents. Optional parent weights and body condition score improve the estimate.
  5. Compare methods. View growth curve, breed typical, and combined range plus daily calories.

Estimates are approximate — consult your vet for health and nutrition guidance.
