How Old Is a Pit Bull When It Stops Growing?

The American pit bull terrier is a medium-sized breed. They are strong, active and powerful dogs with noticeable musculature. During puppyhood, it's important that these dogs receive adequate exercise and a high-quality food source, as recommended by a veterinarian, to ensure their bones and muscles grow at a healthy rate.

Pit bulls can take up to two years to grow into full-size dogs. When they reach full size, females are generally between 30 and 50 pounds and 17 to 20 inches in height, whereas males are 35 to 60 pounds and approximately 18 to 21 inches tall. However, adult dogs that fall outside these ranges are not considered unhealthy, provided their proportion of weight to height is acceptable as determined by a veterinarian.
