Yep, I've always liked this dog a lot, but now she has won me over.
I am speaking to her in a ridiculous voice, and cannot resist throwing her ball when she drops it nearby where I am working, and nudges it at me. If I make any move at all toward the ball, she tears off with accompanying dust cloud in the direction where she expects me to throw it. If I ignore the ball, she will pick it up, and try again and again and will eventually drop it on my foot and hold it there with her nose, with some playful sound effects for good measure.
Each night when I put her on the leash to bring to my van, she pulls me bit harder until she gets to my side doors, and gets all worked up and barks at me if I have locked the door and have to fumble for the key, delaying her entry.
I slept a bit late this morning, and woke up to her standing over me with a paw tapping my forehead.
