Miniature Dauchshund training

Question
Hello, I've had my dog for awhile now. He just turned 2 years old a couple days ago, and we're still having trouble potty training him. It's not that we haven't tried at all, I'm just not sure if we're doing it right...? He has a leash that is hooked onto a zip-line kind of thing in the backyard and we tell him to go potty outside and he will be out there for hours, and come in the house and immediately do his business on the floor. When he was a puppy we had him do his business on a puppy bad in the house, but it got too stinky. He will go outside once and awhile, but he seems to be too distracted by bunny rabbits to go to the bathroom. Can you please help me? We're becoming very desperate.

Answer
Take it out on leash.  Walk around.  They can only walk and hold it so long.  When it finally has to go, lavish praise on it.

When you are around you need to keep a close eye on the dog. Use closed doors or gates to keep it in the same room as you are, and perhaps as I do, a short chain fastened to the computer desk. If you catch it in the act, give it a sharp ''Ah, ah, ah!'' and take it out.

I advise against pads because they only confuse dogs.  Better to start going outside in the first place.
