Bengee was added to the family about a year ago. Eric's mother was living with his brother, his brother divorced and moved into an apartment, and because it wasn't her choice what or where the apartment was, they got an apartment that didn't allow dogs. sending a 14 year old dog to a shelter is practically ringing his death toll, so we agreed to take him on. i think Solar was responsible because Luna didn't have a mark on her, Solar had scrapes on his belly as if he were standing over something and it was trying to kick him off, and Bengee's wounds weren't "bite and shake" wounds... which is what i would expect from a pit. most of the wounds were slashes... collies normally bite that way, instead of grabbing hold and shaking.
Solar has also always been a bit of a loose canon... going over-the-top excited/agressive at seeing other dogs no matter what i did, barking and growling at black people (which i NEVER taught him that, and discoraged it at every turn), and when he would get exited, he got nippy, no matter how much i tried to get him to stop. and i tried everything... positive reinforecment, negative reinforcement, come-to-Jesus moments... you name it, i tried it. when he and Luna played, when she got excited she would grab her ball and shake it... when he got excited, he would try to bite her neck.
