Ionic Therapy technology is now available for your dog! Made from high quality and comfortable jersey fabric as the outer, and a soft inner with the Ionic Tourmaline crystal technology. Tourmaline releases Negative Ions, which cause a change in the water molecules in the dogs body, increasing blood flow to important areas such as the muscles. This brings increased levels of oxygen to the muscles and helps to clear toxins from the body offering therapeutic and calming effects in a smart and comfortable rug. Ideal for use before exercise to prepare muscles for work, and after, to help reduce any lactic acid build up caused by exercise. Also ideal for pets with arthritis and joint issues to increase mobility and lower discomfort caused by the conditions.
