probably because it dewclaws;)
Dewclaw
All breed dogs have five claws so, Golden Retrievers have a fifth claw called a DEWCLAW.

Dewclaw
Typically rabbits have a total of 18 toes. Each front paw has four primary toes, and a small one on the side of the foot called a dewclaw. Each rear paw has four toes.
Theropods are lizard hipped, bipedal dinosaurs with three clawed toes that touched the ground (many had a fourth toe that didn't reach the ground called a dewclaw). Most of them, with the exclusion of birds, were meat eaters.
Dewclaws are the "fifth finger" on the dog's front legs. Since dogs essentially walk on their toes, the dewclaw - the dogs thumb - usually dangles uselessly several inches above the ground. The dewclaw can catch on brush, logs, rocks, or other trail obstructions the dog has to navigate over, under, or around. A torn dewclaw can bleed a lot, but generally it isn't a serious injury. The prescribed treatment is to stop the bleeding through direct pressure. Next, wrap gauze around the dewclaw and leg, then wrap tape around it to hold the dewclaw firmly to the leg. Don't wrap too tightly, however, or you'll constrict blood flow into the lower leg.
Dogs need their claws and I highly doubt you would ever find a vet to declaw them. This is only done in cats.
They are used to help hold bones etc. while eating. Some dogs with larger dewclaws use them for better balance when running. Some dogs do not use them at all. It depends on the size of the dog and breed.
fallout.wikia.com Says, that there will be deatclaws
I'm pretty sure all dogs have a dewclaw on each front foot.
