The alpha by Zeus line of dog muzzles is a safe and humane way to help control biting, barking and chewing while still allowing your pet to drink, pant and even accept treats. The alpha dog muzzle is ideal for those situations where your dog may be stressed or nervous, and where additional security may be needed (dog parks, vet or groomer visits, etc). the muzzle can also be used during walks to help protect your pet from foraging and eating harmful items; as an additional safety measure during training; or to help prevent your pet from wound licking while recuperating from surgery.
