Dog Weight Predictor (Puppy Growth)

How It Works

Puppies grow at different rates depending on breed size. Toy breeds reach adult weight by 9-10 months, small breeds by 10-11 months, medium breeds by 12-14 months, large breeds by 15-18 months, and giant breeds may not reach full size until 18-24 months. Growth follows a sigmoid (S-shaped) curve: slow at first, then rapid during the "growth spurt" phase, then tapering off as they approach adult size. Male dogs are typically 10-15% heavier than females of the same breed. If your puppy is growing much faster or slower than predicted, consult your vet to rule out nutritional issues.
