I tried it on my foster dog who is anxious in new situations. It did nothing to calm her. I feel like it actually amped her up to a small degree.

My dog needs these, she is so nervous and anxious without one on. German Shepard/Husky mix, naturally very high-strung, is so much more comfortable with a calming collar on.

I had great hopes for the collar working. Our puppies continued with fighting and regressing with training.

Wonderful!!!! This has changed my dog. He is a mixed breed, almost 2 years old. It has calmed down the barking and jumping on people

My dog out of nowhere started having major anxiety, panic attacks. The vet recommended this particular collar. I also bought their brand of chews, I don’t know which one worked. It has definitely helped calm him along with the chew.

I purchased the ThunderWorks Calming Collar and the diffuser. The collar made a noticable difference with my 18mo old boxer/pit rescue who's suffered with bad anxiety issues from the beginning. I didn't want to give him prescription pills all the time or even semi-frequently so my vet actually recommended the ThunderWorks products. It's not a miracle worker, but when he wears his collar he's noticably happier, calmer, and doesn't jump and run if a piece of paper falls of a table. (ya it got that bad). He stays calm with even loud noises and activities that normally give him major anxiety complete with bad shakes/shedding/etc. I cannot vouch for the other calming products, and the diffuser didn't seem to make much difference. However, this collar is brilliant! He doesn't mind it at all and works well! It's part of my regular monthly subscription now! I highly recommend giving it a try for your fur baby, it could be the non-medicated help that's exactly what they need! Note: The ONLY reason for the 4 stars versus 5 stars is becuase you put on the collar and trim off the excess length. I kept about 1/2" extra for ease of removing and putting it on. The clip that holds the collar in place is very difficult to push the collar through and tighten, and very difficult to pull off. A minor irritation that doesn't outweigh the benefits my pup, Tim gets from it!

I liked this product and it has helped a lot! My dog can't get out of it as easily as a regular collar.

wonderful, almost instantly put my dog a french bulldog, at ease. Highly recommend this product as well as the room diffuser. Thunder ease
