I unexpectedly caught the last 15 min of this episode but it was enough to remember how much I enjoyed this one. It was very sad how the dogs were treated but it did bring attention to the brutality of dog fighting. Having 3 dogs myself, I can't imagine people being that cruel to their animals. I loved that they brought Cesar Milan in on this episode. I've watched his dog whisperer show and he's absolutely incredible with dogs.
I also was pleasantly surprised to see Dean Norris in this episode, being a fan of his characters from Breaking Bad and Under the Dome. Of course, this episode was prior to both of those shows but it's cool to see some of my favorite actors in earlier roles.
I remembered liking this episode as well for Brennan's sympathy and compassion for the dog that committed the murder. In most cases, she remains distant and strictly scientific, but I enjoyed the fact that she got emotionally involved and went as far as trying to adopt the dog. The scene between Booth and Brennan in the end, burying the dog was very sweet.
TJ was incredible and heartbreaking in this one. I only caught the scene between Hodgins and Sweets when they were talking about how Hodgins hated everyone and how angry he was at Angela and Zack. Although I prefer Hodgins happy, most of the best scenes are when he's unhappy and this is definitely one of them. I really felt for him.
