Basket Cage Dog MuzzleS with Adjustable Straps Size 1 (XX Small), Size 2 (X Small), Size 3 (Small), Size 4 (Medium), Size 5 (Large), Size 6 (X Large), Size 7 (XX Large) - by, Downtown Pet Supply
How to measure your dog for these muzzles: Measure the circumference midway between the tip of the nose and eyes, under the chin and over the top of your dog's muzzle. Take that number and ADD 1 inch for SMALL and MEDIUM dogs, ADD 2 inches for LARGE dogs. This number becomes the SNOUT SIZE.   MUZZLE SIZES:  Size 1 fits SNOUT size 6 - 6 1/2 inches, Size 2 fits SNOUT size 7 - 8 inches, Size 3 fits SNOUT size 8 1/2 - 9 inches, Size 4 fits SNOUT size 9 1/2 - 10 inches, Size 5 fits SNOUT size 10 1/2 - 11 1/2 inches, Size 6 fits SNOUT size 12 - 13 inches, and Size 7 fits SNOUT size 14 - 15 1/2 inches.  If you are in-between sizes, choose the larger muzzle.  Example 1:  If you have a miniature schnauzer and you measure your dog's snout and get 7 inches, ADD 1 inch. Your SNOUT size is 8 inches.  You should order a Size 3 muzzle. Example 2: If you have a Saint Bernard and you measure your dog's snout and get 13 inches, ADD 2 inches. Your SNOUT size is 15 inches. You should order a size 7 muzzle. Brand: Downtown Pet Supply
