Not sure.. I do know that one of the dogs is intact and she has used him to breed..the other male dog is fixed and the female has seizures. Another thing, when she first got the Dobe, she was going thru some rough times with the Boyfriend and she was contemplating moving and she was asking advice about starting up her own breeding kennel. People talked her out of it saying she should set it up for a rescue since thats what she was supposed to be all gung ho over anyway....Hmmmmmm
