Doggy drinking-fountain etiquette

Mia, as seen in this video, is as feisty as ever, despite her medical condition. In this video clip, taken in the summer, Mia gets bossy with Hollywood, my 95-pound Mastiff-yellow lab mix. Pay close attention in the beginning to when she looks above her head as Woody approaches the drinking fountain. Being the sweet boy he is, Hollywood just rolls with it and backs away, moving to the other side. He knows Mia's behavior like the back of his paw! Today was a good day for Mia. She did well with just some coughing. Tonight I gave her an extra COQ10 capsule -- opened it and put the contents under her tongue -- and her asthmatic-like bout almost immediately stopped. More about that later.
