Hi, I have two Yorkiepoos who were 1 year old when I got them and not housebroken yet. I have been working so hard to do so and they understand what to do when we go outside and I tell them to Potty but can't seem to get it through their head not to go in the house. They never go in my car when they go with me which is great. How do I get them to understand it is not OK to potty in the house? They are 1 1/2 now and if I can't get them trained i guess I will have to get rid of them, but I love them so much and hate to.
