Baron still marks and he is neutered. I was wearing Belly Bands on him, But, he was diagnosed as having Pancreatitis and it hurts him to have the pressure on his belly. So, I'm back to a house blanketed in puppy pads and watching him like a hawk. Also, My 8 y.o. Papillion has started to mark too since Baron is marking. Sammy is neutered also. I put belly bands on Sammy and he wiggles out of it every time... No more male dogs @ my house!!!
