Hi! I am going through the same issue here with my 5mo Zeus. Even though he doesn't pee or poop his bed, he only will poop in his crate. I am taking him out constantly and he does pee but I don't think it has hit him yet that he is doing the right thing. I praise him every time he goes...
I don't want to use a puppy pad because I want him to understand that the only place where he can do his business is outside. I am probably taking the steepest and bumpiest road on potty training but only hoping he will get it soon
Good luck to both of us!
