Pay attention to the sizing. I think I have the right size for my female Belgium Malinois, but I'm struggling to keep them from sliding around. I have yet to put them to the test during a thunderstorm or fireworks. I had the impression these also had noise-cancelling technology - they don't. At $59+, I found the product over priced. On the other hand, if they work and my dog doesn't melt down on Independence Day, I'll gratefully amend this rating.
