when do lab puppies reach full growth
All Grown Up. While much depends on the individual dog, labs reach full size by the age of 18 months. By this point, he's added weight, but it's not fat. Regular exercise helps develop the bone and muscle that pack on pounds by this late stage. His total height and weight depend on various factors. The size of your dog is easier to estimate if you've seen the dog's mother and father. The American Kennel Club standards for an ideal full-grown lab declare that a male dog's height at the withers is between 22.5 and 24.5 inches, and a female dog's at 21.5 to 23.5 inches. The approximate weight of a male, the AKC asserts, ranges between 65 and 80 pounds; female dogs weigh 55 to 70 pounds.
