This premium protective collar is designed to protect pets from reaching injuries, rashes, or post-surgery wounds. Pets are able to eat, sleep and play at ease while staying protected. The collar has an inflatable inner bladder made of a plastic vinyl that is inflated through a two-way air valve. Once inflated, the size and thickness of the collar function as a soft deterrent. The inner bladder is protected by a pliable plastic outer jacket lined with a durable canvas material to resist bites and scratches. The collar is held in place by inserting the pet s everyday collar through the ProCollar s three inner rings and securing the ProCollar with a Velcro strap. Machine washable.
