Thunder wunders works!!!!!

My German shepherd always freaks out during our monsoon thunder storms and I feel so helpless not able to calm him I tried the thunder wunders and to my works!!! He doesn't care for the taste of them but I put them in chicken broth and he gobbled them downhes 123 pounds so the chart suggests that he takes of them and within 25 minutes he was CURED!!!!!!

I am very pleased with this product. Eeyore has calmed down a lot and he sleeps better now than before. I think it is the melatonin that calms him and he isn't shaking any more. I use it combined with his thunder shirt which probably makes it more effective. I recommend it.

Helps some

When we were in training class with our adopted min pin, instructor had an exercise of starting soft sound train in background. Our dog reacted in fear before any of us were even aware she had turned it on. Ares really suffers with storms, fireworks and some household appliances. We wanted to try these to see if he's get any relief. Not "magic", but it does seem to make him sleepy and more likely to nap through an episode. Ares still hides in bathroom or under a bed.

Doesn’t work

Thought this was working but my dog ate the entire jar accidentally and was as if nothing had happened. Clearly not having an impact . I guess I’ll stop buying them now .

Work great, when my dog will actually eat them!

My dog gets extremely stressed and anxious whenever there's storms, fireworks, things that sound like fireworks, even just wind and rain sometimes. I've tried a lot of different treats and remedies for her and nothing seems to help her. Unfortunately once she's already stressed she won't eat anything, and I can't get her to take these treats most of the time even if she's not worked up BUT the few times that she has actually eaten them they definitely seem to have a calming effect. She's around 65lbs and only two treats makes her pretty sleepy!

Not sure if it is right for my dog

I did get these as an alternative to another product. However, I do not feel as if they work quite as well for my dog. They may for another dog, but I have a very anxious dog during storms and I probably will not try these again.

Cocker spaniel

Works pretty well on my cocker. He slept through much of the July 4 fireworks, but was still bothered when the booming finale came at the end. Not sure if anything would have helped, I was even freaked out and I had music and tv on!

Happy 4th of July

My sweet granddog, Jude, has such a terrible time with fireworks and thunder. These not only had a calming effect on him physically, but we played games and gave them as treats to distract him. Much better.

excellent product

My rescue doggie is going through Heartworm treatment. In needing to keep her calm for several months, especially during the thunderstorm season and 4th of July celebrations, i thought i would give Thunderwonders a try. She is calm, content & relaxed yet not overly so that disrupts her daily interactions. Decided to get a couple more bags ! Good product!
