For proper sizing measure dog from base of neck to top of tail. Please remember that some breeds have a wide range of sizing. Be sure to measure your dog for accurate fit.
IMPORTANT: The clothes are sized to fit a dog who is an ideal weight. NOT for overweight dogs. If your dog is overweight you may want to take special care in bidding on an article of clothing for your dog. The measure may be accurate but the sweater may not fit because of his size so you may want to go up a size.
