Muzzling does not harm your pet and protects both your pet and the groomer. In some cases, muzzling may even calm a stressed pet, allowing the grooming process to continue. We do not muzzle unless your pet gives us reason to. Other methods are used to calm your pet, muzzling is a last resort. We prefer to use elizabethan collars(Cones) before resorting to using a muzzle.
