My dog would have them off her head in about 2 seconds. Good idea though if you could keep them on.. Ever tried putting sunglasses on your dog.. they don't seem to like things on their heads.. at least mine doesnt' anyways.

I think they're GREAT!!! Lucy used to love to fly... and I always worried about the noise. Now she's about deaf...or just ignores me... but I'd have sure had some of these if I'd known about them sooner! I imagine she would, like any dog, try to get them off right away too..but like anything else with an animal, it takes more than one try (usually) to teach them. Well worth the effort in my opinion!!
