My first thought after seeing my partner (dog or otherwise) collapsed is "What's wrong?? Get this poor dog to the vet!!"

I think he was pissed that he had so many witnesses to the tragedy. I don't care if he was a veteran of the force. He killed his partner, plain and simple. He should do some jail time. Afterall, they consider canine partners members of the force.

May he rot in hell for what he did. He's very upset. He damn well should be!
