I have a almost 4 month old jack russlle terrier and she will not learn. I always find someplace in my back room with her mess. My parents have gotton realy tired of her. SHe goes out but when she comes in 20 min later more mess... I have no idea, and 1 min ago she went right next to me on the carpet. She is causing my house to stink, and advise, please help, and fast.
