Your Dog’s Own Body Warmth Makes This Blanket Therapeutic Every dog can benefit from the natural heat therapy this blanket provides. You’ll find this blanket ideal for both injury recovery and prevention. With its polyester exterior, the blanket is both water resistant and breathable. Inside, we’ve lined the blanket with our state-of-the-art Welltex fabric containing ceramic powder. The ceramic reflects your dog’s natural body warmth and creates a soothing far infrared thermal heat. This gentle heat therapy increases blood circulation and reduces inflammation, eliminating many of your dog’s aches and pains so he remains comfortable and active. Laces at the front of the blanket allow for adjustability. Attached wrap-around belly strap keeps blanket in place with zipper opening for dog’s tail. Blanket has reflectors on each side for enhanced visibility. Instructions for Use Introduce our Dog Blanket gradually to your dog. We recommend letting your dog wear it for a maximum of four hours per day for the first 2 – 3 days. Thereafter, let your dog wear the blanket overnight. Physical response to our Dog Blanket varies.
