Doggie in the herbs

I've been reading a few blogs with stories of disrespect, like picking flowers from others gardens. I am reminded of last month. My daughter was filming a video in our back garden, and had hired volunteer extras. One couple came with thier little dog. During a break in the middle of the shoot, the lady dog owner took the pooch for a "walk" in my garden. She led him over to my herb bed, and let the little pup pee all over my herbs. There was the whole rest of the yard to let him tinkle in!! I didn't know what to do or say next, and dog and owner was called back to do the next scene.
