Paw Brothers Premium Nylon Muzzle Size 0 Tiny 4" - 4.5"
How to measure your dog's muzzle:
Wrap a lenght of tape around the muzzle, just above the nose. Please your index finger between tape and muzzle making sure that the tape is loose enough to slide around the muzzle. Measure tape and choose closest size. It is better to have a fit that is slightly loose than to be too tight. Your dog needs to have free tongue monvement to pant and lap water.
