"Rice" in the poop is a classic sign of tapeworms. It is better to deworm both dogs just in case. He should really improve once you have cleared up all his issues. 
You probably know this, but you can get tape worms too.  You know what to look for and it is easily treated. Hopefully not, but at least you know what to watch for.

Silver Bullet is like a kid. He is having too much fun to want to go to bed. He will settle down with your guidance and be a great dog.
You are definitely the right person to have him. 

I can't wait to see how he looks when you get him well and strong and a bit more mature.
