Newton is now back to his old routine. He is eating his food like a champ and his poop is back to normal. I think that he is feeling much better. His energy level is up, but he still gets pretty tired easily. Our daily walks take us to the corner of the street and then we have to turn around. It isn't much, but I know how much he loves to take walks. He gets to excited when I get his collar and leash out. You can't help but smile at his excitement.
