Thanks for all the comments.
Ms Daisy's behavior really does amuse/amaze me. I always thought that dogs were so attuned to their sense of smell that video really would not be all that enthralling to them. But Ms Daisy has proven that theory wrong, at least that it does not hold true in all cases!
I could not resist making a video of her watching her previous video in the first post... Very artsy IMHO.
