Bogey had a run-in with fleas that we've taken care of and she's not itching anymore. But where the fleas bit and where she was biting at them has left little black scabs/spots all over the inside of her back legs. Just wondering how long they take to go away and if there is anything I can put on her skin to help them heal faster. Someone said it's probably blood and fecal matter that will wash away with a bath. Any help is appreciated.
