My brother had a lovely boxer named Hera. She had originally belonged to a couple who ran a local pizza place. Apparently, they fed Hera what was left over and the dog had a real love of pizza, spaghetti and garlic bread. One time, my brother and his wife got a pizza and placed it on the bed in their bedroom. They were going to watch a DVD while having supper. He ran upstairs to grab some cola and cups of ice. When he got back downstairs, the center of the box had been torn open and the middle of the pizza eaten. Hera was hiding in another room, looking extremely guilty and covered in pizza sauce.
Another dog we had - I say we since I took care of her when he was working on the road - loved cornbread. I have no idea why. One of us gave her a piece since she was begging for some people dinner scraps, thinking that would put her off. Nope. She nearly ate the entire loaf.
