My Westie is 1 1/2 yrs old, and potty trained, or so we thought. Lately he has been pooping and peeing inside, although we take him out 3 times a day. We have now increased to 5 times per day, and that does not help. Is it canine "adolecent defiance" as I have read? We do not spank him or rub his nose in it, or otherwise punish him. Our current strategy is to keep him under close supervision at all times, and in the crate when supervision is not available, and if we catch him in the act, make a loud noise to get his attention, and take him outdoors to finish. Every time we put him in his crate, he cries, moans, and howls like the world is coming to an end. We took him to the vet recently, so there is not a health problem causing it. What am I doing wrong?
