MediPaw protective boots for dogs (Derwood, MD)

I have 2 MediPaw boots to protect bandaged paws or legs when taking a dog outside; one boot is size Small and the other boot is size Medium. Both are in excellent condition aside from some dirt on the sole of the Medium. I think it is the Soft Bandage boot shown here (scroll down for sizing): https://medipaw.com/collections/boots/products/soft-bandage-boot Please tell me which size you want.
