鎮靜保健棒：大型犬 by Woof

Fireworks night used to mean hiding under the bed, but this big chewy stick kept my shepherd busy for a solid half hour while the magnesium and passion flower did their quiet work. She was snoozing ten minutes after the last boom. Worth every penny for that peace of mind.

My anxious lab actually chewed through one of these during a fireworks drill and was calm within ten minutes—the 20-40 minute playtime is spot on. The passion flower and magnesium combo seems to do the trick, and she doesn't even notice she's eating something meant to settle her down.
