We have found more pros than cons from the information we have gathered throughout the years. We feel with having the dew claws intact that the dog will benefit with stability and traction for most of their everyday movements like running, swimming, and digging. When a dogs run, their front feet often bend to the point where their dewclaws come in contact with the ground. At high speeds (especially when turning) or on slippery surfaces, these dewclaws provide the extra traction and help stabilize the carpel joint.
