What does a Boxer dog look like?

Boxers have strong, muscular builds and square-shaped heads. These pups have broad, blunt muzzles with distinctive underbites, where the lower jaw extends slightly beyond the upper jaw. They have dark, expressive eyes and ears that have historically been cropped to stand erect, although e ar cropping is a controversial practice and has been banned or restricted in many countries due to animal welfare concerns. There is no medical reason to crop a dog’s ears, and vets do not recommend it.
