Order a Forehead Strap for brachycephalic dogs (e.g. French bulldogs, pugs, Boston Terriers), for dogs with a short nose:large pant ratio (e.g. bully breeds, St. Bernards, Mastiffs), or for dogs in which there is risk of another dog potentially grabbing at the muzzle and pulling it; the forehead strap is removable if it’s not needed.
