We are freaked out, we have a beautiful Yorkie that is 3 years old and this is her second litter.. the strange things is she loves her puppies and has been a wonderful Mother.. until this weekend when she eat her two female puppies. She had four puppies, 2 female and 2 males.. has anyone every heard of such a thing? Our vet was shocked, nobody would have thought she would have done it.. she was eating Science Diet for nursing Mothers, and taking calcuim tablets daily. Any thoughts?? Please help..
