I have had dogs all my life and this story just does not make since to me. I find it hard to believe that a puppy that young would do this without a reason. How did the puppy get to the baby to begin with? You know the child had to have been crying and yanking his feet a way from the pup. It's an automatic reflex. Seems to me the pup had help or was he just a poor little scapegoat?
