Our MagnaCu Blanket is designed to keep your dog fully balanced with our strategically placed magnets on major acupuncture meridians and points. The mesh portion of the blanket is copper infused fabric. This combination provides soothing delivery of magnetic therapy and copper therapy. The blanket addresses the major muscle groups, as well as the stomach and lung meridians. Great for those sore muscles. Our blanket is made of a copper infused mesh which is cool in the summer or can be used under a winter blanket when the temperatures drop. The magnets we use are Grade 8 Ceramic unipolar. Remember this is the only magnetic/copper dog blanket on the market.
