My dog is 4 yrs old. I got him about 6 months ago from a shelter. He is fixed. He came with a dog buddy. So I have two dogs ages 4 and 5. The 4 yr old keeps peeing in the house. I will let him out. But when I bring him in he pees. I yell at him stick his nose in it and then lock him in the laundry room with the lights out alone for 30-60 minutes. Then I let him outside saying "poddy outside!" He comes back in and pees again. What can I do to make him stop?
