Anyone ever effectively dealt with this issue? It's getting to the point where we are considering giving him up. We all love the dog but over the last couple months he has started peeing on various items throughout the house. He has hit my sons backpacks, shoes, guitar amp, our rifle cases, my dresser ect.... He waits till a bedroom is open and sneaks in a pisses on something. We try to keep the doors closed but all he needs is a 30 second window and he does it. Ive tried the old make him smell it, but he knows when he does it and runs and hides in the laundry room and will not come out. We are at the end of our ropes, he has done this probably 30+ times and got my oldest sons backpack no less than 5 times alone. Ive done some research and every article says it's because of a new pet or person in the house and that's not the case. He is a 6 year old German Shepherd.
