Julie,
and don't forget to make rude noises with your mouth

. Whatever will get the dog's attention.
At one show, I had a battery-powered cat that meowed and waddled. It was great at getting the dogs' attention. Until a Dobe jumped off the stand, attacked and ate it

.
I have play balls that I squeek and roll; furry toys that I squeek and toss; a kitty that mews when I press it; a hedgehog that makes really rude noises when squeezed. But my favorite was "the Red Devil." This toy made no noise but it got every dog's attention when I tossed it. In fact, several people had me take a photo of it at one show because it got the attention of dogs that were impossible to get.
Unfortunately, after 3 years and 4 beheadings, it bit the proverbial dust at the hands (mouth actually) of Cassidy The Destroyer. And I've never been able to find a replacement. Sigh. You can see it in my avatar under Cassidy's daughter, Juneau.
Anyway, toys are a very important part of the arsenal.
Jim
