Too cute! I've got some little helpers (a pair of corgis) who help in just the same way!
You must be working them to death! They are pooped! Haha. If only my dog would be so chill. Instead, he comes and drops his toys in my lap while I try to work.
Mine alternate between the above positions and offering me those droopy no-stuffing squirrel toys. They operate only on the full tilt and off positions. :)
