I used to live with a dog who really, really loved to be petted. He would hop up next to you on the couch while you were reading a book, on a laptop/phone etc and very deliberately hook your forearm with his "wrist" (not sure the right term, first major leg joint above the paw) and pull your hand/arm towards him for pets. Cute the first few times but he was so persistent and deliberate about it, it became a little annoying!
