Nickel sheds a LOT (there are times when chunks of fur come out, or if I pet her my hand is covered in fur). She also has dandruff looking flakes on her fur... on her stomach there's a bump (it reminds me of a mole, not an abscess) above her nipples, and the skin on her nipples comes off. Her poop is really soft and smells of dog poop, and it gets stuck on her nails and there is residue left on her butt hole (is that what you call it?).
Should I go to the vet?
