Dew Claws Dogs Veins. No, dewclaws don’t bother dogs. Unlike front dewclaws, rear dewclaws usually have little bone and muscle structure.

At high speeds (especially when turning) or on slippery surfaces, these dewclaws provide extra traction and help stabilize the carpal (wrist) joint. Dogs that have rear dewclaws often end up injuring them as they are attached to the leg with just skin. The tendons are attached to muscles.
