Housbreaking

Question
i have a 1yr old male long haired Chihuahua that is as stubborn as can be he seems to be going # 2 under my sons bed and i have no idea why we've trained him to go out side and he goes out side does his business and then when he comes back in sneaks into my sons room and stinkys in there. what gets me is he wont pee in the house but he'll stinky in the house.we have scolded him every which way you can think of and nothing seems to be working. we also have a new baby and since having her it seems to have been getting worse. please help! thanks Britt

Answer
What you may want to try is a crate-how you do that is to keep him there all the time except to go outside,to go for a walk,to play,to get fed or to take him somewhere,and do this for about 2-3 weeks then slowly let him out more

It works because they don't like to soil where they sleep

It also seems like he is jealous of the baby,and you also lessen that by spending time with him whenever you can(and of course you take him out of the crate for that)then he won't feel so left out
