Use your own collar or order .
For correct dog muzzle size, measure the circumference of your dog's nose about 1 inch below the eyes. Order the muzzle that is about 3/4" to 1 inch bigger than the circumference of the dog's nose.
Small 9" to 10" circumference
Medium 10" to 12" circumference
Large 11" to 12 1/2" circumference

Your dog MUST have enough room to pant & open his mouth when the dog muzzle is on.
The dog muzzles circumference must be larger than your dogs nose measurement.
If your dogs nose is the exact same size as the dog muzzle, your dog will not be able to open his mouth to pant.
