Four Paws Quick Fit Muzzle For Dogs helps stop biting, barking, and chewing, but allows panting and drinking. Its made of strong nylon and is completely washable. The walk-about quick fit muzzle doesn't have a lot of buckles that always need adjustments. Only one initial fitting is needed.
Measure around the snout circumference. To do this, measure your dog's snout by wrapping a measuring tape around it, one-half inch below the inside corners of its eyes. The dog's mouth should be closed as you do this; make sure the tape is snug but not tight or too loose. Be a responsible dog owner and do not leave your dog muzzled for long periods.
