The first pictures are those of having the dew claws removed. This article also suggests having a Vet do it.
Other articles also say that removing dew claws is strictly up each individual person. If it's the type of dog that will running through the forests, briars, or anywhere else they might get caught on later, then it's a good idea. But, not all owners have these removed.
