John, while our dog isn't completely terrified of the fireworks, he does get a bit anxious and grumbles/groans/barks. We started using Richard's Organics Pet Calm a few years ago, and we noticed a huge improvement. He'll curl up on the couch or in the bed, and sleep/relax for a few hours; long enough to outlast the fireworks. My aunt's dog is completely terrified, she has to put her in a Thunder Shirt, give her doggie Xanax, and put her in a closet. I always feel so badly for her.
