The Boxer is a medium to large, short-haired breed of dog, developed in Germany. The coat is smooth and tight-fitting; colors are fawn, brindled, or white, with or without white markings. In the UK and Europe, fawn Boxers are typically rich in color and are often called 'red'. 'Brindle' refers to a dog with black stripes on a fawn background. Responsible breeders use available tests to screen their breeding stock before breeding, and in some cases throughout the life of the dog, in an attempt to minimize the occurrence of these diseases in future generations.
