We bred boxers for 13 years. We always had the dewclaws removed by the vet at 3 days. Our vets typically charged $3-5 per puppy and they did it at the same time we had the momma checked after the birth of the pups so no extra trips to the vet. I would always recommend getting it done on any active breed. We bought 2 puppies that did not have their dew claws removed, and both of them at some point in adulthood during a romp or run, cought the dew claw and tore it. Very painful for the adult dog. Vets as well as individuals can miss the nail bed on a puppy(although the vets if they are careful will get it). We have had adult dogs with misformed little claws that were done by a vet, and by an individual at home. A misformed toenail will grow if the nail-bed is not completely removed.
