Ears:
Boston Terrier ears are small and, in their natural state, can be alert, floppy or alert with a flop at the tip. If they're naturally floppy, the pet parent may want to have them cropped, so they're permanently alert. The AKC breed standard allows for the ears to be cropped. Ear cropping involves surgically cutting away the outer part of a dog’s ear. Veterinary groups along with many US states and countries have banned this procedure due to medical and behavioral reasons. If you are interested in this procedure, schedule a consultation with your veterinarian.
Eyes:
Their eyes are dark, large and round and set wide apart.
Nose:
Their noses are black and round and have a well-defined line between their nostrils.
Coat Length:
Their coats are short and smooth.
Coat Color:
The Boston Terrier comes in three main colors: brindle (reddish with black stripes), seal (black with a reddish tint that shows up in sunlight or bright light) or black, and all have white markings on their nose, between the eyes and their chest. Although not standard, you may find blue, red, white or grey Boston Terrier dogs.
Tail:
Their tail is low, short, straight or corkscrew-like.
