Things You'll Need
- Flexible measuring tape
Instructions
Choose one of the two most common types of muzzles. Either a basket muzzle or a nylon muzzle is usually sufficient for the average dog owner. Nylon muzzles allow dogs more freedom. Veterinarian Gary Landsberg states that "basket muzzles provide many advantages over traditional nylon, mesh muzzles: they allow panting and normal respiration, the dog may be fed soft, small treats, and normal canine communication signals such as lip curling, growling or snapping can be monitored."
Use a flexible tape measure, like one used for sewing, to measure the dog's snout. Wrap the tape measure loosely around the snout, just beyond the nose. Place two fingers under the measuring tape and record the measurement of the snout plus two fingers.
Buy a muzzle using the nose circumference you measured as a guide when choosing the size. Muzzles will also list the dog's weight and breed to help you choose a size. The nose measurement should be your primary consideration, with the weight and breed being secondary.
Try the muzzle on your dog to test for a proper fit. The muzzle should fit securely, preventing a bite while also allowing the dog to open his mouth enough to pant. The strap should fit just under the ears, along the side of the face and just behind the ears on the top of the head.
Ask your veterinarian or dog trainer to check the muzzle if you are unsure if the size is correct.
