I'm really sorry to hear about that It's completely understandable. I don't think anyone on here is going to bash you for re-homing a dog who could have seriously hurt or killed your child.

I don't know that newspaper is a good idea, really. It works for some people, but the best training method for most is a crate. Newspaper will teach your dog that it is okay to go in the house and then, what do you think he will do if he sees a newspaper on the floor once he has been housetrained? Crating him at night will eliminate messes in the house. You need a crate that is big enough for him to stand up and turn around, but not big enough for him to potty at one end and sleep at the other. Dogs like to keep their den clean. Nova *never* went in her crate, not even the first night. I kept her crate by my bed and took her out during the night if she cried. During the day I took her out every 1-2 hours at first, and less after she had been here for a while. Just remember that a puppy can hold it for one hour more than it's age -- for instance, when your puppy is 2 months old he can hold it for 3 hours.
