Dog Training Muzzle - Size: M - Inner Diameter: Approximately 14.5cm - Band Length: Approximately 13cm - Approximately 33cm - Color: Brown Thank you for viewing. I purchased this without properly checking the size, and it didn't fit, so I'm selling it. (It was a little too small for a slightly larger Corgi) Please check the size chart in the photos. I only put it on once, so there are no scratches or stains. I wiped it down with an alcohol wipe just in case.
