What about those dewclaws?

The right front paw of Northwoods Blitzen (CH Elhew G Force x Northwoods Vixen, 2016) shows normal growth and wear on dewclaw and toenails.

The issue of dewclaw removal is worth re-visiting on occasion. It’s not a life-threatening controversy but there is general misunderstanding…beginning with the possibility of a dewclaw tear.

I’ve been training, hunting and trialing pointing dogs for almost four decades. I’ve watched hundreds of dogs work thousands of hours in all kinds of terrain and conditions. Yeah, I’ve seen dewclaws torn but much less than regular nails and not even close to injuries to limbs, tails, eyes, ears and skin.

Besides, dogs use dewclaws. I’ve seen dogs groom themselves and scratch using their dewclaws. And they are used in the field because dewclaws show wear just like regular nails.

Perhaps most importantly, dewclaws are natural parts of canine anatomy. Five tendons attach to each dewclaw. At the end of those tendons are muscles with a distinct function: to prevent torque on the leg. When a dog turns while cantering or galloping, “the dewclaw digs into the ground to support the leg and prevent torque,” Dr. M. Christine Zink, Director and Professor, Department of Molecular and Comparative Pathobiology at the Johns Hopkins School of Medicine, wrote in the linked paper.

“If a dog doesn’t have a dewclaw, the leg twists,” she continued. After a lifetime of that abuse, carpal arthritis and injuries to elbow, shoulder and toes can result.

Betsy and I don’t remove dewclaws from our puppies. We base that decision on science—on research and clinical observation by Dr. Zink.

Most veterinarians admit that injuries to dewclaws are rare.

Again, Dr. Zink: “It is far better to deal with an injury than to cut the dewclaws off of all dogs ‘just in case.’”
