The present invention relates to an improved mask apparatus for veterinary applications. The mask may be used for dogs in particular. Most prior art masks are conical. This leads to problems in comfort and effectiveness. The present mask has a cross sectional profile and an opening shaped similar to an animal's muzzle. It has a flat top and a flat bottom, slightly wider than the top, and rounded sides. It also extends backwardly from the top of the opening to the bottom of the opening, so as to comfortably cover the commissure of the animal's lips.
