The best thing ever
I have 2 dogs, both collie x kelpies. Both have different issues as they are rescue dogs. One barks at very little thing that goes past the window and she has from the day we got her. The other one has started to get anxious over the past 5-6 months when out on her lead and at training sessions.I had tried the sprays and collars and nothing worked on either. After being banished from the training field as one of my dogs had started to lunge and snap at anyone, either 2 or 4 legged, I was at my wits end as to what to do. My trainer was coming around to see me but not for a week. It was horrid to see my little girl with her tail under her and visibly shaking. I had read about thunder shirt but didn't believe it could work but I had nothing else to try. I did get one from the local pet store as i wanted it immediately. Got it home and put it on woofy dog. The change in her was amazing. It was like she was a chilled out pooch. She still goes to the window and looks out but the barking has stopped. I couldn't believe it.Straight onto Amazon to order a second one for anxious dog as it was nearly £10 cheaper.We were allowed back to training but only at the top of the field where she could still see the dogs. It had got to the point where she would walk in with her tail down and lunge at all. This week she went in with a waggy tail and although she had the opportunity she didn't lunge or snap. It was like she was on something. I nearly cried. Sorry to waffle but the change was nothing short of a miracle. I have my gorgeous girl back. Highly recommend although results might vary.

Surprisingly Helpful
I was a bit skeptical as it just seems like a coat. My dog is a small mongrel; she just weighs 5kg. She gets nervous in the car, with strangers, with other dogs and loud noises. She also gets super excited when she sees my dad and if she's in her cage and she sees my dad she goes crazy. The XS fits really well on her. First try with the thundershirt she just stood still and looked at me. I eventually got her to move around and come for a cuddle just to get used to it. Second attempt was in the car and she was much better than usual. There was no shaking, slight bit of panting. The cage was where I saw the biggest difference. Instead of going crazy scraping the cage she was standing and was looking around but was calm. I'm actually really pleased with this shirt. I haven't been able to test it with other dogs yet but I can't wait for Halloween so I can test it with fireworks. So far this is the best money I have spent for my dog.One thing to understand is that this is not a miracle product. It is not going to work to the same level for every dog and will not fix every problem your dog has. Saying that though it is a really good aid to try and help your dogs problems. Make sure to follow the instructions that come with the shirt as they really help. Also use youtube for tips or if you can't work out how to fit the shirt. I do not regret this purchase at all.

Aids submission in dominant dogs
I bought this for my 5 month old german shepherd. He suffers from extreme anxiety when out but indoors he is totally hyperactive, constantly play biting us and completely uncontrollable. He also behaves quite dominantly towards us. I found he doesn't really like wearing the coat, (it seems to make him itch)but when he wears it indoors he is a different dog, definately calmer but sad, he lays whining and looking very sorry for himself! As soon as I take the coat off he is away like a bullet out of a gun, careering around, play biting etc again.Unfortunately it doesn't seem to make any difference to his anxiety when he's out.In defence of this product my dog has very extreme behavioural difficulties stemming from a neurological problem, so maybe he is a particularly difficult customer!I would recommend this product to other pet owners not only for anxiety but also as a training aid. As I find my dog is much calmer and more responsive to me when wearing it, so I put it on him for short training sessions - next step to get him to do as he's told when he's out with distractions around him.The design of the coat is good, very stretchy so it's not restrictive for the dog to wear, no zips, buttons etc for the dogs to chew. However, the velcro does collect dog hair and my dog seems to get hot in it even in winter, so maybe they need to design a light weight summer model? The price is reasonable, so if like me you are at your wits end with your dog I think it's worth a try.

Not a bad product
So, i decided to purchase the Thundershirt to try and elliminate my dogs barking when out of the house. I researched the product online, and watched numerous videos before deciding on this purchase. My dog also jumps over any guests that arrive, but we werent bothered about stopping that, only the barking!The Thundershirt arrived, and we tried it out straight away. I was amazed. My dog turned into a different dog.. so calm, relaxed, just well like a dog should be. she was even calmer when my parents came over.So i was very hopeful for it to work outside the house with her barking..... well it didnt! shes still exactly the same. We tried the training guide that comes with it, and at first she was listening more and we were getting somewhere. But, its as if the effects of the Thundershrt have worn off as it no longer calms her down indoors or helps her listen outside.I would recommend this product if your dog doesnt have major training problems, maybe that just needs calming down a bit. Other than that, its not great. She does however love to wear it, and it looks great so i am keeping it.

Works so much better than I had hoped.
I am very pleased with this product and surprised by how well it has helped. My lurcher has been terrified of loud noises like fireworks since I've had him (he's a rescue). He normally has a full blown panic attack: smacking his lips, shuddering/shaking, hyperventilating, over heating, staring so wide eyed you can see the whites of his eyes all the way round his iris' and pacing about refusing to settle. I've tried various things with mininal effect. This year I bought this thunder coat. I should have bought it earlier but didn't get my act together to sadly his first night wearing it was 3/11/20 and people had already started setting off fireworks. That first night I wasn't convinced it was helping to be honest, but as I hadn't had chance to egt him used to it before he needed it, I knew that was my fault and nt the coat. I followed the instructions like putting it in my laundry basket so it smelled of me etc. By the second night he was hearing it (4/11/20), he was noticeably calmer and actually sat down and settled with us on the sofa, something he has never managed before during fireworks. This evening (5/11/20) is his third night in a row wearing it and there have been a huge number of fireworks. As you can see from the photo and hopefully the video (the video doesn't pick up most of the fireworks, but trust me there were lots the sound on my phone is just rubbish!!), he is like a totally different dog. He did prick up his ears and look up for a few of the very loud bangs, and very occasionally he shuddered slightly, but the majority of the time he was calm and settled. No pacing, no hyperventilating, jone of the more extreme signs of anxiety. He even nodded off at one point which I would never have thought possible before. We normally have to have the TV or radio on to try and drown out some of the noise, but didn't even need to do that this evening. I am so impressed with the difference this coat has made and I'm very very hopeful that effect will carry on every time we use it for him.

Highly Recommend! Excellent coats that work.
Excellent!!I bought one of these years ago from a pet shop randomly for my Staffy who has serious separation anxiety and obsessive tail chasing issues.I used it on him and it defo helped so much that I didn’t need to use it and forgot I had one!But I travel with my dogs (I now have 4, a shih tzu, Staffy, bullmastiff and blue French bulldog). which means long days in the car and over night on the ferry in kennels for them.My Shih Tzu is very highly strung and even though the vets would give him tablets for travel he would still get so worked up he’d chew the kennel till he would bleed his gums! We even tried flying them instead and same outcome.It was either stop travelling with them (really not an option as life dictates travel) or find a new solution.Then I remembered this coat!! Couldn’t find them anywhere online in Ireland but thankfully Amazon came to the rescue!!Ordered and arrived before we were due to travel and I used them on the way over and back on the ferry and guess what........No bleeding gums and not highly stressed dogs!!!And no highly stressed Human!! As I dreaded the kennels on the ferry as I never knew how they’d be when I’d check on them and the upset of having to put them back in during the journey knowing they were hurting themselves also.I used this over and thought maybe it’s just a fluke.......Then came back (summertime and was not going to put it on as thought it would be too warm for them, but saw a vet in the US recommending them for the 4th of July so knew wouldn’t be too warm!), and again No upset or hurt dogs.Chilled and happy. Of course they were still happy to get off the ferry and out of the kennels. But they were chilled and not bleeding!!Really Highly recommend and will be a regular in our routine from now on.I put them on and off the dogs a couple of days before travel for them to get used to wearing them and get the smell of “home” etc.Sorry for long assed review 😊

Works really well so far!
Only received it yesterday but so far so good! My anxious rescue adolescent dog has been so calm all day, he's been napping for record time and not constantly on the go looking for mischief.It's not a miracle cure for sure, he still needs training when out for walks & around other dogs and people but it's definitely improved his quality of life. He seems much more restful in himself.

Wonderful ThunderShirt !!
I ordered the ThunderShirt for my three and a half year old Maltese dog after searching for something that would help him from being stressed and barking his heart out every time he heard fireworks. It arrived earlier than I expected which was great as where I live fireworks are set off way before bonfire night. From the moment I put it on him he relaxed completely and didn’t attempt to bark or run to the door once despite the firework noises being relentless. It was unbelievable really and he has worn it for the last three evenings and has been very happy to have it on. It fits perfectly and the material is lovely and soft and stretches well. I will say though that the Velcro fasteners are strong and do make the Velcro ripping sound but my dog was already used to this from the Velcro fasteners on his dog coat so it didn’t bother him. The other thing I noticed was that he didn’t bother barking when an animal appeared on TV which is a real bonus as he usually barks at every creature even a cartoon one! So this will be great to put on him for a while if we want to watch an animal film or programme in peace. I’m so happy that we have had a stress free fireworks weekend at last. The ThunderShirt is worth every single penny I paid for it.

Funciona
Al menos mitiga al sujetar un poco y envolver al perro con el temor al ruido de los fuegos artificiales. No es magico pero si ayuda.

Un aiuto concreto contro l'ansia da abbandono. Ha funzionato!
Ero scettico sull'efficacia di questo genere di cappottini, ma essendoci stato utilissimo devo ricredermi. Abbiamo preso la taglia M per il nostro cane di 17 kg (un incrocio simil Malinois) che soffre terribilmente di ansia da abbandono quando resta solo a casa.🟢 PRO: EFFETTO CALMANTE REALEFunziona davvero: Il principio della pressione costante sul corpo ha un effetto "abbraccio" che funziona. Abbiamo notato un netto miglioramento: il cane è decisamente più sereno, si agita molto meno e ha smesso di ansimare continuamente vicino alla porta.Vestibilità ottima: Nonostante la corporatura snella e slanciata tipica del Malinois, le fasce in velcro permettono di regolarlo al millimetro, aderendo perfettamente al petto e al tronco senza limitare i movimenti.Qualità: Il tessuto è robusto, traspirante e non fa sudare il cane. Già lavato in lavatrice a 30 gradi ed è tornato come nuovo.🔴 CONTRO: ABITUARLI GRADUALMENTENon aspettatevi di metterlo e uscire subito di casa. Abbiamo dovuto farlo indossare per pochi minuti nei momenti di relax, premiandolo, per farglielo associare a qualcosa di positivo. È un percorso, ma i risultati si vedono.💡 CONCLUSIONE:Per noi è diventato una salvezza. Se il vostro cane soffre quando restate fuori, vale assolutamente ogni centesimo. Consigliatissimo!

Great for the quality and brand name
I know there's a lot of thunder vests out there and a lot to choose from. When I purchased this, I looked a good solid quality over price. When I got it and put the shirt on my cackapoo, I was really surprised at how it holds true to its name. It works for: thumder storms, fireworks, seperation anxiety, travel, and vet visits. Although my cackapoo still gets scared a bit when fireworks go off and wears the thunder shirt. So I'd honestly say the shirt works 85% of the time. Still quality material though. Sizing and fit for my small cackapoo is really good and doesn;t giver her aan uncomfortable feeling. The velcro is easy to attached to any dog and it holds to their body keeping them safe from danger. For the long term quality, I'd really give this a go and try it for your dog.
