Can someone please help me! I have a rottweiler/german shepherd boy that's 5.5 months old, he doesn't bark or make any kind of sound to let us know when he has to go potty.

He has a crate with a separator but it isn't working he still goes inside his crate. I'm loosing my patience know and if this problem can't be corrected he will have to go. I take him outside every hour he goes to the same area every time so I know he knows that he is to go outside.

Can someone give me some concrete help to save Shadow.
