As we receive orders, we have begun compiling a list of breeds and sizes which work best according to their length (and weight) and according to customer responses. Some pets have fallen into another category (printed in red) simply because all dogs are not built the same even within their own breed.
** Important Note** As dogs age, they lose muscle mass but do not shrink in length so weight should only be secondary in determining size. In most cases the length supersedes the weight.
Below is an approximate measuring guide to help fine tune your order. You’ll be measuring the entire underside length (down the center) of your pet.
a) Begin at armpit level at the chest
b) Go in between the front legs, past the chest/abdomen and in between the back legs. (a line down their center)
c) Go to the base of the rectum. Don’t go past, you don’t want the fabric to cover it up.
