We have a 2 year old cattle dog mix who suffers from separation anxiety. Based on a friend's suggestion, I did some research and decided to try the Thundershirt. I brought it home, presented it with a treat, as the instructions suggest. She was very nervous as I was putting it on her, but as soon as it was on, she calmed down and just chilled out. I put it on her a few times, for 30 minutes to an hour at a time. She was fine with that, and quickly got over her nervousness of getting it on. I was feeling so hopeful! I decided to try the ultimate test on a short outing. I had to pick my child up from school, which is less than 2 miles from my house. I put it on her, she went into her crate, and I left. I returned 15 minutes later - 15 minutes! - to find she had chewed it in half, and was, as usual, sitting in a massive puddle of saliva. Clearly, this was not a good fit for my dog.

So, not 100% sure if it's just my dog or the shirt or what. However the shirt appears to make her more nervous. We are going to work on wearing it more often with more treats involved.

My dog is terrified when we go outside and I was hoping the Thundershirt will get her calm down. Unfortunately it does not work for her for some reason. She starts shaking as soon as I put it on her so I had to return it.

I tried the Thundershirt for a full month, but it did not help my dog's separation anxiety. I will say however, that it might just be her needing behavioral modification in addition to this. I'm not sure, but this just did not seem to help.

We had rescued a Miniature Pinscher/Chihuahua cross puppy (approx 6 months old) from a local shelter. If you know dog breed personalities, the Min Pin has a very energetic, hyper personality. Our pup definitely seems to be mostly Min Pin! He's HIGHLY active and he just never seems to calm down. He's now about a year old. Of course, we made his crate a luxurious place with a cuddly soft blanket, a couple of chew toys and a small bowl of clean water and when we left the house we initially had him stay in his crate to potty train him. Since we rescued him from "a cage" at the shelter, once he was potty trained, we didn't want to keep him in his crate all of the time, so we started to allow him to be free when we left the house. Well, when we're gone, he finds anything he can to chew and eat. He's destroyed our shoes that were out by the door, has somehow gotten some rubber coasters off of our coffee table and eaten them, and tends to get a craving for our cat's litter box treasures. (YUCK.) At night before bed time, before we move him to his crate to sleep, he just doesn't unwind and just drives us crazy. So, we tried calming tablets, Chamomile tea, a calming scented collar, and eventually we tried the Thundershirt. The Thundershirt actually seemed to work initially. However, it did make him seem very odd. He would just stand and stare into space and seemed almost like he was "in a daze"... but he was calm! It seemed to really change his personality all together, and I wasn't sure if I liked that. But, when we needed him to calm down it did work to calm him down. So, we decided to try putting the Thundershirt on him when we left the house since he seemed to have some anxiety while we were gone. Unfortunately, since he couldn't find anything else interesting, he decided to chew himself out of his Thundershirt and continue to nibble away at it. So, it was destroyed. =( I was amazed that he could chew himself out of it like that! Anyway... if this shirt could be made out of a material that is too strong to chew out of, or maybe made of something that repels dogs from chewing... we might try it again. I would still recommend it to others since it did work to calm him down while it lasted.

I have used a thunder shirt on my one dog for years. I ordered her a new one after seeing they had updated the style. This one is more contour, so it snuggles your pet better. Making them feel secure regardless whether there is thunder, or fireworks. Thank you for helping to make our pup more able to tolerate the scary noises that bother her so much.

I have a 10 pound Yorkie that is very skittish of any noises so I got excited when I heard about this shirt. It works for a thunderstorm that is not directly overhead but when it comes to a strong storm or fireworks that are in the immediate area, I didn't see a great improvement in his anxiety level. The shirt is made of good material and easy to put on. My dog likes when I put it on so it must make him feel secure.

My Yorkie is 7 lbs. She shakes and pants uncontrollably and hides under the chair with the frequent afternoon and evening thunderstorms. We are experiencing them almost daily here in SW Florida now. I purchased the Thundershirt and truly noticed a significant change concerning her extreme fear. She senses a storm coming from miles away, so I put it on when she starts reacting a storm, thunder or rain coming and it really eases her anxiety.
