The quilted nylon outer fabric provides cosy warmth for your dog and with the (synthetic) fur collar, it is a real eye-catcher! Limited Edition! The inside of this rug is a lovely fleece which not only grips better to prevent movement but also keeps you dog lovely and warm! We love these rugs and use them on their own dogs, they are quick and easy to put on the dog and keep their belly clean with the strap reaching under and has elastic in the fastenings so as not to cause any discomfort to the dog. To get the perfect fit for your dog, measure from the end of their neck (where their collar sits) to the base of their tail. If you have any problems measuring please email us and we will be able to advise.
