Disclaimer: If you purchase a scavenger guard from us without purchasing a Big Snoof muzzle at the same time, we will build the guard based on muzzles we have in stock in the size you order. However, there is some variation in the specifications of wire muzzles, even though their sizing is standardized. We do our best to make these fit properly, but we cannot offer refunds if the guard your order apart from a muzzle does not fit perfectly onto the muzzle you have. It’s also very important to ensure you choose the correct muzzle size and coating style if you do not purchase the muzzle along with your Scavenger Guard order to ensure we make a guard that fits correctly.
