I have to second (or third, or whatever we're on) what Ashley said about making it fun. And yes, don't do the finger thing. My dog is food motivated big time and used to stare at ONLY my hands, because that's where the food came from. He's a total velcro dog and trust me, you don't want that. Now that he's more experienced, he watches me, not my hands.
Also, if you've never been to a run-through, trial, anything like that before, that could be it too. My first run-thru (what we can fun runs), my dog ran off the course and well, went another 100' away. So embarrassing. Another run, he went to go beg for food from someone on the side.
My first trial, he couldnt' run out (gated) but he did go visit the judge and the workers every run.
My second trial, he ran out the entry gate....after running around wild for awhile.
My third trial, he was crazy, but he actually was paying attention to me.
My fourth trial, he was actually focusing...ON ME!!!
So, give your dog some time to acclimate to the type of surroundings. For awhile, every new place will have new scents, people, noises, etc. Once your dog is more acclimated to just "going to a trial" anywhere....then she'll start to truly focus on you.
BTW, I had to do a LOT of whooping and happy hollering to keep it fun for him since he's sooo food motivated. Obviously, me yelling happy things, wasn't any replacement for food, but it somewhat worked.
My whole point is.....going out for the first time is never easy. Many of us have had dogs run off or ignore us. It goes with the territory of being new. But once you and your dog get used to going to trials (or just run thru's), she'll get used to it and then she'll start to focus on you again. So, give it time.
Good luck!
