When I can, I use Tammy, the world's BEST dog wrangler. When she's not available, I try to use the owner, but most of the time they are worse than working alone.

Tammy knows what I need and if a dog is too out of control to be off leash, she knows how to hold the leash so it doesn't get too in the way or pull on the dog's neck too much which can make it look funny.
