I don't understand that thought process either. Like, my dog is 100% house broken, she hasn't had an accident inside since she was a puppy. And she even knows that if she has to throw up, she has to do it outside - she'll start gagging and bolt for the door to be let out. A friend of my mom's, on the other hand, has an 8-year-old shih tzu and she lets him do all his business in the house. She puts down those puppy pad things, but a lot of the time he doesn't do it on the puppy pads. She never scolds him or tries to correct the behaviour. And guess what? She's a 250 pound butter barge.
