I recently found out that Maggie is a tennis ball nut!!! It's so funny when I grab a tennis ball and hold it over my head, she'll get into position. Run a couple of feet infront of me, one ear up, and get ready to run for the ball! Lol so is anyone else's dobie a tennis ball freak? How do you get them to catch it in the air? Maggie won't do that, she let's it fall to the ground before she grabs it and runs!
