We have two dogs here w/them removed. When I touch the scar, they seem to feel pain. They use those like little thumbs.
If it was on the back, and floppy, I'd say get rid of them - the front, leave them.
It's really "cosmetic" anyway, they do that w/show dogs to give the front leg a neater appearance. The
only advantage I've seen to them being gone is 2 less nails to clip
