When measuring for a dog blanket, please take in consideration the build of your dog. Is your dog wide, thin, holds it tail up or does the tail hang low? Once you have the measurement you may notice there could be multiple sizes your dog may wear. This is because there is a 2-3 inch zipper opening that you can put your dogs tail through, mostly for those breeds that carries their tail high. We recommend considering the smaller size of blanket and not going up a size, because of the 2-3 inch zipper opening. The end measurement of the size range is the end of the tail opening to serve as a form of placement on the dog, once you have a collar to base of tail measurement.Care:Machine washable up to 86°F or 30°C. Use normal detergents that do not contain bleach or fabric softeners. Air dry only, do not tumble dry. Back on Track products are not to be compared with magnetic therapy.I have used other blankets on my dogs for several years, but it was when I started using the Back on Track dog blanket that I noticed the difference. My older dog Lotus has a hip joint problem. He is very sensitive to the cold and becomes stiff easily so Back on Track has been a great help... compared to the usual dog blankets available. Stiffness that may appear after a rest period completely disappears after diligent use of Back on Track.
