Dog Size Calculator (Puppy Growth)

Puppy weight calculators provide estimates based on breed averages and growth patterns. Accuracy varies depending on the method used and individual factors like genetics, nutrition, and health. The most accurate predictions come from knowing the parents’ sizes.

Small breeds typically stop growing by 8-10 months, medium breeds by 12-14 months, large breeds by 18-24 months, and giant breeds may continue growing until 2-3 years old. However, dogs may continue filling out and developing muscle until they’re 3-4 years old.

Yes, but with less accuracy. For mixed breeds, consider the paw size method, observe growth patterns, and if possible, try to identify the dominant breeds. DNA tests can provide more accurate predictions by identifying the breed mix.

Puppies need more calories per pound than adult dogs. Follow the feeding guidelines on quality puppy food, adjusting based on your puppy’s body condition. Large breed puppies need special food to support controlled growth and joint health.

Genetics (parents’ sizes) is the primary factor. Other influences include nutrition, health, exercise, and whether the dog is spayed/neutered (which can affect growth plate closure timing). Environmental factors play a smaller role than genetics.
