Hmm.well if I was a dog and could go anywhere I guess I would too...
Its going to be hard if they have marked around the house. My dog was restricted to the kitchen until she got better. Shes crate restricted now due to a leg injury and on one day a week was letting me know how much she hates it by peeing on the bed. I took her to where she is supposed to potty (I left some of her pee there) and said "good potty" all happy. I then went to her bed where she had peed and showed her and said "no potty bad potty" in lower voice and went back and forth many times. I also reward with treats on good potty, which is a whole other issue that I posted about as it worked a little too well. She hasnt had an accident since. What my friend did was everytime the dog went somewhere other than on his pad or outside she would move his food bowl over the place he had gone. I guess they dont like to pee/poo where they eat so every time he had an accident thats where the food went right on top of it. She had to move it aroudn a few times till It worked..
