Diesel will come up to you, sit down, and lean right on in, lol! It takes some leg strength, let me tell you! My Dobie Max is the same way too, if I'm on the couch, he will sit down, with his back to me and then turn just his head back...like he's just waiting for me to scratch his back, silly dog!
Saints are also known for being wonderful feet warmers. They will literally sit on your feet when you are sitting down. We had a lovely female when I lived at home, and she was always fun to have around in the winter
