Animal Sizes are determined, for use in our website, by basic and generalized sizing.  These include X-Small, Small, Medium, Large, & X-Large. 

These are used as generalized sizes for all different types of pets, making it easy to refine what would be best suited for your pet.  If you are not sure how you might categories your pet, you can choose a range, or several different sizes, to try to refine your search.
