Description:The Boxer is a medium-sized, square built dog of good substance with short back, strong limbs, and short, tight-fitting coat. He should have a broad, blunt muzzle and an expression of alertness. He should have a fenced yard to roam in, but will do in a city environment if walked daily. The Boxer is considered a "people dog" adapting well to other dogs and children. He should never be aggressive, but rather even-tempered, but does make a good guard dog.
