ProCollar® is a premium protective collar that is designed to protect your pet from reaching injuries, rashes, or post surgery wounds. The ProCollar® has an inflatable inner bladder made of a plastic vinyl that is inflated through a two-way air valve much like a beach ball. Once inflated, the size and thickness of the ProCollar® 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 ProCollar® is held in place by inserting the pet's everyday collar through the the ProCollar®'s three inner rings. The velcro strap should be placed at the back of the neck and then adjusted for a perfect fit.
