house breaking a puppy mill rescue

I recently adopted a 1 year old male neutered Pomeranian. He was rescued from a puppy mill along with 54 other dogs. He does not know any of the normal things a dog of this age would know. I am having a great deal of trouble housebreaking him. I take him out at least every 2 hours. He does go outside but he also will piddle in the house and in his crate overnight. He also eats his stools sometimes. He is otherwise healthy, adorable and very affectionate. My husband and I adore this dog. I also have 2 other dogs that are totally trained so I don't know where the problem is. I love this dog but it is driving me crazy. I don't know what to do? Any advise would be greatly appreciated.
