The ZenCollar is a premium protective collar that is designed to prevent your pet from reaching injuries, rashes, or post-surgery wounds. It has an inner bladder made of plastic vinyl that is inflated through a two-way air valve much like a beach ball, to serve 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 ZenCollar is held in place by inserting the pet's collar through the the ZenCollar's three inner rings. Place the velcro strap at the back of the neck and adjust for a perfect fit.
