Using your Quick Fit Dog Muzzle is easy. First, gently place the muzzle over your dog's snout for a comfortable fit. Then, take the straps and bring them behind your dog's head. Fasten the plastic buckle securely. If it's too tight or loose, you can adjust it by pulling the strap. When using the muzzle, make sure your dog is calm and don't leave your dog unattended for long periods. For maintenance, you can wash the nylon part with mild soap and water. Let it dry thoroughly before using it again. This way, your dog's muzzle will stay clean and in good condition for a long time.
