Frequently Asked Questions
How accurate is this prediction?
Weight predictions are estimates. Genetics, nutrition, health, and whether the dog is spayed/neutered all affect final size. Small breeds are typically easier to predict than large breeds. Accuracy is best when the puppy is 14–20 weeks old.
When do dogs stop growing?
Small breeds: 10–12 months. Medium breeds: 12–15 months. Large breeds: 15–18 months. Giant breeds: 18–24 months. Dogs may continue to fill out (muscle, chest width) even after reaching full height.
