Thanks, everyone. It's 1am and it's difficult to sleep. We made Sam chicken and rice tonight, and it just made things worse. He even became aggressive toward our 2yr old yorkie-bichon, and he absolutely loves him. The thought was to cut out all the extra ingredients in his food. The idea was a fail. I feel like I can't do anything right for him. Tomorrow is our appointment with the specialist. Hopefully we will get some answers.
