The Back on Track® Greyhound Coats are water resistant and breathable, high quality polyester garments, lined with a unique heat-reflecting ceramic fabric. This gentle therapy allows an increase in blood circulation which can help muscles and joints to stay supple and maintain mobility, so that the dog can remain as active and as comfortable as possible. The rug boasts reflectors on either side for increased visibility, a zipper opening for the tail and an adjustable laced front. Length: Measure back from withers to root of tail.
