New collar on and his anxiety and general demeanor was calm and easy going again

Works very well. When the collar is about 3 weeks past time to replace, his anxiety increases (forgot to change).  New collar on and his anxiety and general demeanor was calm and easy going again. It does not completely stop the anxiety, which results in slight aggression with unknown dogs. This helps to reduce the anxiety and with continued behavioral work both have made a hugh difference.

I put the Thundershirt on and within seconds the dog was calm and no longer shaking!

I rescued a troublesome dog, who barked non-stop whenever I left.  A severe case of separation anxiety.  After one day wearing this collar, the problem stopped and the neighbors quit complaining.

I was skeptical, but the minute i put this on my dog he seemed more calm; and that's saying a lot for my crazy dog who has many anxiety's. It also seems to be comfortable, as he never tried to wriggle it off. I would recommend this product!

I have to admit, I was very nervous to try this bark collar out. I felt bad about resorting to this method, after trying other training methods that were just not working. My Yorkie was rescued at age 7 and while otherwise sweet and loving- barked non-stop at anyone entering the house, and even worse- would wake the entire family up with his barking after midnight, when he decided he needed company (for reasons that don't need to be explained in the review, he cannot sleep with us). It was causing sleep deprivation for all of us- and we really needed to change the situation.
I ordered the collar (It took 2 weeks- way too long IMO, but it was not Amazon, it was another seller) and read the directions and put it on him before I went to bed. Lowest setting (there are 3 levels)- he barked two times (second time with a yelp) at 1am, then stopped. Barked once at 2am, then stopped. Barked again at 4am, stopped. I was wide awake and sad for him during these nights...but it took just 3 nights for him to completely get it- that if he barked, we were not coming to get him, and he would get an unpleasant sensation. We are on Week 2 with the collar and I would say it is the best money I have spent in a long time. I put the collar on right at 10pm when we go upstairs, and take it off around 6/630am. This is not a collar that you leave on the dog all day- some people might, but for us- that is not necessary. Recently I tried the collar on when we had a serviceman come out. My dog is very protective of me, and will bark non-stop if any visitor besides family comes in the house. Especially men- so I put the collar on before the visit. He barked twice when the man came inside the house, and then stopped. He stayed by my side the whole time and did not make a sound. I actually get the sense that the dog is happier not barking incessantly (I am not saying this to make myself feel better). He seems like a less nervous dog. Perhaps one could say he is just scared that he will get a "shock" but I don't get that he is scared or nervous about that....when before I felt like he was very agitated and out of control when visitors came over. He never fights me putting the collar on him, though it is bulky for a small dog (he is 15 lbs). So there you have it. Used correctly and if your dog is receptive to this training, the collar is amazing. I can't speak for the batteries yet- I have had it for two weeks and am very careful with turning it off when it's not being used....and we only use it for about 8 hours a day max. I ordered a 5 pack of extra batteries to have on hand as well- per the reviews, it sounds like the off brand is less expensive and works just fine. I hope this works as well for you as it did for us!

We saved an abandoned cat that had been in many cat fights and was injured. Needless to say, he is massively violent towards other cats. He was impossible to handle and with our 3 other cats in the house, he was a ball of nerves and too tense to even sleep. So he got his own room and one of these collars. He still cant be around other cats, but the collar has removed a TON of his nervousness and he is much calmer. We can let him out in the house with the others put up and he actually acts like a normal cat, even with the other cats scents all over the place. Overall he is very calm and happy because of this collar.

At about 4 weeks its obvious when the collar has been used up. He is anxious, irritable and hard to control. Put another collar on, and within a day he is lovable and on my lap purring. Amazing.

Ok I have a hyper active,super "sensitive" and agressive
barky type dog.

update: now I have put him in the crowd situation that make
him "fear/agressive. the result is he is "uninterested" in
lunging after people,he seems to FOCUS this also helps
me RELAX..knowing he won't be hard to correct.

he is able to unwnind and take naps without
freaking out at every tiny "sound" . he sleeps way better
not reacting to every "branch breaking outside the window"

its only day 2,i am happy with this product,he
is happy....so be it. I bought 1 collar not here on
amazong,but this is where i review it.

i like it,but some will hate that smell.

keep the "powder" that comes loose,in a baggy,and
the collar does not"undo" very easy,so no worrys
about it coming off. its rubbery like a flea collar.

My Bichon Frise, Oliver, was very hard to live with before I got this collar. He has a very loud voice and he barked at people and dogs. He also tried to chase cars, which  could have gotten him killed. Fortunately the few times when he ran by me and out the door before I could grab him, there were no cars driving by at that moment. After using this collar, he is like a different dog. He won't chase a car and he will stop barking if I tell him to be quiet or I just say, "It's okay." I was hesitant about buying it at first, since I was afraid of hurting him. I found that you can control that by how hard you jerk on the leash. You have to jerk it when he misbehaved--pulling on it will only choke your dog. You need to just jerk it back quickly once to convey the message. Just don't do it too hard if your one who doesn't know his own strength. The first time I jerk it, he screamed, because it hurt, but it was well worth it since it did not permanent harm and may have saved his life. He will not chase cars when I have him on a leash with the collar on. He used to pull really hard in an attempt to go after the car and almost pulled the leash out of my hands. Now, while on the leash with this collar, he actually ignores the cars as they go by and it really only required about 3 times when I had to jerk the leash for him to learn this. He got calmer about the cars, people and dogs with each incident. I am amazed at how quickly it works and how well it works. On the first day of using it, the TV repair man from DirectV came over to work on our TV connection. The dog sat politely and quietly throughout the time of his visit. I had NEVER seen him do this and I NEVER thought it was possible! We were just stunned as he was like a different dog. Even the TV guy noticed it, since he had come by before and had to contend with a threatening, obnoxious dog. In the long run or actually much sooner--you will benefit not just yourself, but also the dog. I say it benefits the dog, because he calmed down and lost his anxiety about visitors. He also changed in a life-saving manner when it came to chasing cars. He really is much happier. He is much more content, safer, calmer and just at peace--a new dog! --A better dog! The initial discomfort that they experience in training is well worth it for the long haul--both dog and owner are happier. I am VERY impressed with the results!

Additional note: The ends of the prongs are a little blunted. In the photo it looks like they are needle-like, but they are blunted at the tips, so that they DON'T pierce the skin or feel like needles.

We love this bark collar! Now my 8 lb dog does not want to attack everyone because of her anxiety with other dogs. She is as meek as can be which is better than a barking maniac. We are a pet therapy team and go on visits with other teams - we had to stop for awhile as she was so anxious! I got a second one as my new puppy is barking already obsessively at other dogs, I'm ready for her if she doesn't let up!

This collar is magic. On the second setting (green and blue lights), the collar returns to the lowest setting after 30 seconds of silence. This works wonders for our "scaredy-cat" dog. He is afraid of some of our large, male friends and works himself into a fearful barking frenzy. This collar snaps him out of it without over correcting. He is calmer and happier around unfamiliar people when wearing it.

Thank you! Our Maltese would work himself into a tizzy barking. Now with the collar, he's able to break that barking cycle. As a result, he seems much calmer!!

My cat has recently been under a great deal of stress due to a move and the unexpected loss of his bonded mate. Crying at all hours, scratching things, and following my husband and I constantly were three new (and unwelcomed) character traits we were experiencing. This went on for a month. We took him to the vet just to make sure he was OK physically, and the vet recommended this product. I'm happy to report there is improvement. He is calmer and happier than he has been since our move and the loss of his best buddy. The vet told us to expect him to mourn for a few months, but this has definitely taken the edge off.

Before using the collar my cat was losing patches of fur, constantly agitated, and almost completely stopped showing affection to people and my other pets. The collar was recommended by the vet (as the plug-ins only helped a little). I was very hesitant to get the collar after reading the reviews and hate the idea of my cat having something strapped to him that he can't get out of in an emergency. The collar ha worked wonders, my cat is back to his old self, spending time with the family, cuddling with the dogs,and his fur has grown back! My parents even noticed a difference in his behavior when they visited! It's remarkable how much this collar has helped him. I should note that the collar really only works for 2-3 weeks (I can literally tell when he needs a new collar because of how quickly his agitation level increases- especially with the other cat). I can't give the collar five stars because I HATE that it won't breakaway. Please make a safe collar!!!!

Noticed significantly less scratching and chasing of the tail after we applied the collar. Pup had no issues wearing it and now we don't have to worry about him hanging out with other dogs at the park.

My dog was making enemies in the neighborhood by barking so much! I put the collar on him and, the first few days, I pushed the 'vibrate' button a few times, and now he wears it every time he's outside and never barks! Mind you, he's an exceptionally intelligent guy, but this is absolutely the easiest way to break the very bad habit of continual barking.

Was very effective.  After the first few days I didn't have to turn it on to have it help him.  He has calmed down.
