Step1
Measure your dog for the correct muzzle size. Start at the eye of the dog and measure down to the tip of the nose to get an accurate muzzle length. To measure for the proper circumference, start one inch below the eye and measure all the way around the nose of the dog. For proper muzzle fit, you must add length to each circumference measurement. An addition of one-fourth of an inch to half of an inch is required for a small dog. Large dogs require an additional half inch to one full inch. Special muzzles made of mesh material are available for dogs that have short noses.

Step2
Know the types of muzzles to from which to choose to select the best muzzle for your dog. The two main types of dog muzzles are the basket type and the occlusion type. The basket type of dog muzzle allows the dog to pant freely and drink water at will. Basket muzzles are good for long-term use when the dog is outside. The occlusion dog muzzle keeps the mouth of the dog completely shut. Advised for short-term use only (because it doesnt allow the dog to pant or drink at will) an occlusion muzzle may be necessary when a dog needs to visit a veterinarian.
