The muzzle should not press strongly on the bones of the skull or on the muzzle of your dog. Be sure to keep a slight space between the muzzle and the tip of the nose. If the muzzle is properly attached, the dog will not be able to remove it. Choose a muzzle with a vertical diameter large enough so that the dog can open its muzzle properly for drinking and panting. Don't expect the dog to adopt the muzzle easily. Plan a phase of adaptation of several weeks, put the muzzle only a few moments at the beginning. The wearing time can be extended little by little. Do not ask too much of your dog, he may not adapt. Wearing a muzzle should become commonplace for your dog, not a punishment.
