These were suggested by our vet for our 12 year old schnauzer who had started sundowning and getting confused in general. Half a chew helps her to calm down but not get knocked out. She’s 13-14 lbs.

I was skeptical, but I couldn't believe how great these chewable calming chews work. Whether its for fireworks or thunder, or you have a very anxious animal, these work amazing to not only calm them down but also can make them drowsy. I really can't say enough great things about these.

Waited till after July 4th fireworks to review.

I'm very impressed. We got through massive fireworks on both the 3rd and 4th, with no problems. I could have given 4 chews but my dog only needed 3, and no extra

I'm very impressed. We got through massive fireworks on both the 3rd and 4th, with no problems. I could have given 4 chews but my dog only needed 3, and no extra back-up dose. There were no ill effects. He stayed alert but calm. I definitely recommend these. They worked like a charm. (Side note: Don't sniff the bag ... they stink to high heavens:)

Fireworks relief for my dog

Thunderwunders allowed my dog to relax during the dreaded firework season. I love the 4th of July and the fireworks but Zoey does not agree with me. She is a wreck

Thunderwunders allowed my dog to relax during the dreaded firework season. I love the 4th of July and the fireworks but Zoey does not agree with me. She is a wreck and cannot settle until I found this product. Now she can chill on the 4th until 1:30am when they light off the 1/4 sticks of dynamite down at the beach or someplace nearby. UGH!!!
