Are you using something like Petzyme to clean up the messes? If there is any trace, he is going to have the urge to mark those places again. Do you limit water at all? If not, I would highly recommend putting a feeding schedule together with no water in his crate. They sleep all day usually, so it won't be so difficult. If he is having accidents in his crate, it is helpful to feed him in his crate and put the comfiest bed in there while you are home so that he respects his environment. If he sees the crate as a cage, he won't care what is in it. Basically, you need to go back to the basics like you would if he was a tiny puppy. I am not a big fan of the tether method, so throw that one out the door. It sounds like you may need to get some tell bells or make some on your own and have him ring them everytime he needs to go outside. Treat him when he rings them, and hopefully, within a few weeks, he will be much improved. Hang in there! I know how frustrating stuff like that is, but I am sure that with your dedication, he will be a well behaved boy in no time!
