We recommend a small treat inside the muzzle to encourage the dog to put its nose inside. Once the nose is correctly placed, fasten the straps with special care to avoid stressing the animal, be patient, and give it time to get used to this routine. The use of a muzzle is not recommended to stop barking. If your dog barks incessantly, we recommend visiting the veterinarian to determine the cause and possible solution.
