How This Puppy Growth Chart Works

Puppies grow at different speeds depending on whether they are small, medium, or large breed dogs. Small breeds often reach adult size earlier, while large breeds may continue growing for much longer.

This chart and estimator use your puppy's current age, weight, and breed size to provide a rough adult weight estimate. It should be used as a general guide, not an exact prediction.

Puppy Growth Tips

Breed size changes growth speed

Small breed puppies often mature sooner, while large breed puppies may keep growing for 12 to 18 months or longer.

Track weight over time

A single weight measurement gives only a rough estimate. Tracking growth over several weeks is more useful.

Nutrition affects growth

Balanced puppy food helps support steady growth. Overfeeding or underfeeding may affect body condition.

Genetics still matter most

Parent size, breed type, and genetics strongly influence a puppy's final adult weight.
