So Rosie's been digging a lot in the yard. We're working on that, but in the meantime her paws and lower legs get super dirty/muddy. I'm trying to find the best way to clean off her paws/legs. My brushes seem to harsh for the sparse-r hair and thinner skin. I keep thinking a brush like you use on a horse (my horse lingo is pretty limited to my experience riding when I was about 9), I think it was a curry brush? Like a rubber nubby paddle that brushes dirt and dust off a horse? Do they make those for dogs? Or should I just use a towel and rub?
