Rex barks everytime he has to go out to use he bathroom! I figured out the reason he was going in his crate was because Im gone at work too long and he cant hold it. Soo what is the age where they can hold for more than 6 hours? Dh will not walk him for me at all. He says I wanted the dog so I take care of him. Grrrr Im like it takes 5 minutes to let him out and back in.
