Nutri-Vet Protective Inflatable Collar for Dogs has an inflatable inner bladder made of plastic vinyl that is inflated through a two-way air valve. The inner bladder is protected by a pliable plastic outer jacket lined with a durable canvas material to resist bites and scratches.

Directions for Use: 1. Remove pet's collar and run collar through inner ring straps of the protective collar. 2. Reattach collar around dog's neck and inflate by pinching and blowing into air valve. 3. Once inflated, connect adjustable strap securing both ends of collar together. 4. Always monitor your pet for proper collar function. Make sure pet is not able to reach injury with collar in place. 

Sizing is based on the circumference of the neck. Size up if in between sizes or pet has long limbs.
