Some active dogs' dewclaws make more frequent contact with the ground while running, so they wear down naturally, as do their other claws. Double dewclaws on rear leg of dog. A dewclaw is a digit – vestigial in some animals – on the foot of many mammals, birds, and reptiles (including some extinct orders, like certain theropods).
Why do dogs have dewclaws may have been something you wondered as a dog parent. We wanted to know too, so we spoke to vet, Dr. Rebecca MacMillan.
A claw that is retractable is protected from wear and tear. Most cats and dogs also have a dewclaw on the inside of the front paws. It is much less functional than the other claws but does help the cats to grasp prey. Because the dew claw does not touch the ground, it receives less wear and tends to be sharper and longer.
Other cloven-hooved animals (such as giraffes and pronghorns) have no dewclaws. In some so-called "cloven-hooved" animals, such as camels, the "hoof" is not properly a hoof – it is not a hard or rubbery sole with a hard wall formed by a thick nail – instead it is a soft toe with little more than a nail merely having an appearance of a hoof.
