That is so horrible. That is what happened to my little pup except her and her brother made it out with only minor injuries besides a devestated sense of trust towards anyone. She was a crazy pregnant dog her whole life but she loved me and my folks and we gave her the best thing a pup could ask for: a nice home with caring owners and a warm bed. it was crazy because even at the age of 14 if you touched her in certain spots it instictualy caused her to go on the defensive, god only knows what her previous owners did to her before we saved her. she had several "hot spots" where no one, not even me, could pet her. im just glad we gave her a good life, once she came to trust me she was a very loyal dog.
