why do dogs have dewclaws

Dogs have dewclaws because these extra toes serve several important functions. Dewclaws act like a dog's "extra thumb" and provide stability and traction, especially during activities that involve running at high speeds, making tight turns, or navigating rough terrain. When dogs make sharp turns or need extra grip, the dewclaws help them maintain balance and prevent injuries. They also assist dogs in gripping objects like bones or toys between their front legs. In some breeds, dewclaws help with climbing, scratching, and steadying themselves in dog sports. While most dogs have dewclaws on their front legs, some breeds have them on their hind legs as well, sometimes even double dewclaws, which offer similar stability advantages.
