Welcome to the site, or should I say family. We are just that one huge bully family. I love your little Murphy, he is adorable. Now just a warning, we love photos here, so you will be expected to keep it up.
I don't have experience with your acne question, but trust me, someone here will. You can also look on the site, there is a wonderful food rating guide and a ton of before and after food changing stories.
Again, welcome, I am so glad you are here.
