SIZE LARGE: Paw Width 7.6cm, Length 18.2cm, Grip Width 4.6cm. Muti sizes are available and fit different dogs. Please measure your pet before purchase. If your size is between two sizes, it's better to choose a smaller size, because our paw protector socks are stretchy.

The dog paw protectors also prevent your dog from licking and irritating the wound to further aid in healing foot wounds.

ANTIFALL-OFF: Extra adjustable and detachable belt makes the socks keep stay on paws, even if lively and naught pets, never fall off easily. You can adjust the tightness of the belt, but don't fix it too tightly to make sure that your dog feels good and the socks will not drop as well when walking or running.
