I recently got a teacup chihuahua puppy, and he was 7 weeks old when we got him. He is now about 11 weeks old, but we are no closer to house training him than we were before. He is so stubborn, and nothing seems to work with him. We can't teach him anything and he thinks the apartment is his bathroom. Treats don't even work! Sometimes he'll be good about his walks in the morning, but at no other time in the day. We'll take him out, and he'll pee outside, but will both pee and poop inside right when we get through the door. I don't know what to do anymore. Some one please help! Does anyone have any idea of what we can do with him?
