Answer
Crate training is the most efficient, popular way to house train a dog.

I am including information for you to read on crate training and housetraining.

As far as the puppy eating his own feces, there are products you can buy to add to the food that makes the feces unappealing to dogs.  These usually work only as long as you use them.  Once you stop, the dog often goes back to eating the feces.  This behavior is very natural to canines and is often hard to break.
