Hi, I have a 2yr. Old min. pincher mix he is a good dog except that if I don't keep an eye on him he will go to my bathroom & pee on my toilet or the partial wall or his food can. Also I have to keep him locked in his cage at night due to him pooing by the back door.. He knows he has done wrong when I tell him bad, but he still does it. Why? Thanks in advance.:confused:

Because you haven't fully trained him?

Get a copy of how to housebreak your dog in 7 days, and start from square one. You should also consider getting a dog training book or two just to understand how dogs think, understand and behave.
