I understand people being clueless of the dangers of CL (although still very sad to give away a pet on CL), but when a person like you emails them to clue them in -- it's infuriating and doubly tragic that they don't care to take the advice.
We dogsit for a dog just like this one. He is the sweetest boy. Before Michael Vick, I had no clue about dog fighting or bait dogs.
