Exact Measurement/ Measure your pet's width: Simply open a door the minimum width needed for the widest part of your pet to comfortably walk through, then measure the door opening and add an inch. You can also stand above your pet and use a ruler to measure the widest portion of your pet, then add an inch. It is important to add an inch or so, that way your pet will not rub on the door as they pass through. Determine your pet's height by measuring from the top of your dog's shoulders to it's belly or chest and add 2 inches.
