You're not alone. Teddy marks everything too. I have peepee pads in the house for them to do both #1 and #2 but he will mark everything, pee on the pads when he feels like it and still poop outside the pads. He also poops outside when I walk him. London pees and poops on the pads. She is such a good girl. Boys are harder to train. I would like to know too how to start over with him
