Size Small: Inner Sole Length 2.1 inches, Inner Sole Width 1.6 inches. Please measure your dog's paws first, as this is the most crucial step before choosing the proper size. A snug fit is fine; if your dog's paws are between two sizes, choose the smaller size because these dog booties are flexible and roomy. There is an opening design at the back ankle, which makes it easy to put on the dog bootie. There are 4 booties per set, and each dog bootie is fastened via the two long straps which are reflective at night. To use the two straps, first unfasten each strap and temporarily attach each strap to itself before placing the dog's paw inside; after placing the dog's paw inside, unfold each strap again and wrap each strap around the dog's ankle to avoid any confusion. These dog booties feature breathable fabric and non-slip soles for comfort; they are hand washable and can be air-dried.
