Sam will boggle your mind. He's a total psycho, of that I have no doubt, but he also has one glimpse of remorse for poor Linus. I had a bit of hope for our little K9 hero but that hope was quickly dashed when Sam fell deeper into his obsession and paranoia. It was hard to see Sam discard Linus from his affection. It was hard to see Linus' basic needs not be met and realize how animals must feel when us humans don't make them a priority. When we forget to feed them on time or their water bowl doesn't get refilled or we make them wait hours and hours on end before we let them out to potty. It was eye opening to see how emotionally devastating it is to animal kind to be at the absolute mercy of someone else's compassion......or lack there of.
