when they want to play, pee or just be babied by you?
I'm on the laptop and Kodak walked across my keyboard (letters scrambled)took his paw and scratched my hand.
He came back and took the right paw and scratched again to show me he had a small rope toy & a ball. I have to type with one finger and toss the rope and ball with the other hand.
He can go on and on with this before he gets tired and I won't get any work done. It's worth it though, he'll sleep for a little while.
What does your dog do to get your attention?
