Our Pee Guards are designed to be placed between two adjacent X-Pens to prevent male dogs from peeing on each other. The fabric is a super clean, super safe fabric. It is anti-microbial, anti-fungal, odor and UV resistant and the woven material is heat sealed. Can be washed with up to a 50% bleach solution (10% kills Kennel Cough). So it can be sterilized after a dog show. Comes with eyelets along the top and sides spaced 2 feet apart. Standard sizes are listed here but custom sizes available by request. Available in many colors by special request.
