about holding food while they eat it, about using them when climbing rough terrain, etc. I can tell you that I have dissected them, and They are basically a big skin tag with a nail. There's no musculature there, there's nothing really at all that they are capable of doing, so I really do think that they are vestigial. Mine use theirs for things like holding a bone or scratching their faces, but I think they could manage to do those things without them. Im just trying to figure out what peoples' personal preferences are, especially in people who dont show their akitas because they arent worried so much about the illusion of more bone.
