At not quite six months old (one week from 6 months), my boxer Rocky is 22 1/2" tall at the withers and weighs 52lbs. Is this large for his age? He looks bigger than most puppies that I have seen and he is completely in proportion. His dad was show quality and weighed over 100lbs fully grown. He is AKC registered and I have the pedigree back to three generations on both mom and dad. Is this normal?
. I was just curious as to other people's thoughts.
