This Thundershirt is absolutely amazing! My 10 month old Cockapoo had the most ...
This Thundershirt is absolutely amazing! My 10 month old Cockapoo had the most awful separation anxiety and howled the entire time I was out. The neighbours told me he always howled with no let up until he heard my car on the drive, once for almost 3 hours. He was agitated and upset when I got home and took ages to settle down. When I was in the house he would howl if I went into the kitchen and closed the door and followed me all over the house. He woke us up two or three times through the night, every night. He also was beginning to snarl at other dogs on our walks. I bought this Thundershirt and the moment I put it on he was a changed dog. I walked into the kitchen and he stayed calmly in his basket. I went out for a few hours and filmed him while I was out and he just watched me drive away, snuffled about a bit and settled down to sleep. He stayed asleep and calm all the time I was out. He no longer snarls at other dogs son our walk and is altogether a happier, calmer dog. His anxiety has gone, and it seems accumulative. The more he wears the shirt the more calm he is getting, even when he's not wearing it. I can't recommend this shirt enough. You must get the correct size though, even if it takes a few attempts, and you MUST wrap it tightly. It doesn't restrict their breathing or movement, and it doesn't rub or hurt. Its very soft jersey cloth and he now sleeps in it all night. I've filmed him all night and he doesn't make a peep. He waits to have his huggy nightshirt on before he goes to bed. I think he's grateful not to be feeling what must have been the most awful anxiety. What a blessing this shirt has been. I've bought one for all my friends dogs and my daughters doggy.

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.

This is a good product, well made
This is a good product, well made, and really does seem to help to calm our rescue dog down. He wasn't sure about it to start with, and seemed to view it as some sort of punishment, but lots of fuss and treats soon made him realise it's a good thing. He often looks quite relieved when we put it on him when he's getting overwhelmed and overexcited, he sits beautifully for me to put it on which he wouldn't if he didn't want it. The reason I've dropped a star is because of the velcro. It's good strong velcro and there's plenty of it to get a good fit, but unfortunately with velcro comes that noise which is not good for calming an anxious dog - it seems a little counter-intuitive. The velcro part is over with fairly quickly but I still think it could be avoided altogether. We have another shirt made by a different company that we also use on our dog, which works just as well but has no velcro, it just slips over his head and has little 'sleeves' for his front legs. This one is much easier and quicker to get on our dog because he's not jumping every time he hears the velcro.

Partially effective, which is better than nothing
We've exhausted over the counter products to help our very anxious dog and this was our last thing to try before he goes back to the vet. It does nothing for his separation issues and general anxiety. It does, however, seem to calm him down a bit sometimes when on a walk. Not as effective as we hoped for but better than a lot of other products that have done absolutely nothing. At least it also doubles up as a coat for slightly chilly evenings!

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.

Exceeds expectations!
I was very sceptical as to whether this would work but it absolutely does We have a 5 year old Border Collie who is terrified of loud noises and especially fireworks. She is usually petrified for hours after the fireworks have stopped. We have now used the jacket several times and while she is scared when the noises are happening she calms down really quickly and definitely fined the jacket comforting.

Surprisingly effective
I would never have believed how effective this product is, if it wasnt for my niece telling me how well it worked with their dog. The first time we used it was during a storm and whilst it didnt stop our dog shaking during the storm she recovered immediately after it stopped whereas in the past it could be an hour or two before she calmed down. On fireworks night the combination of Thundershirt on in advance anticipation and some loud background music meant she didnt really go into that shaking state at all. It might not work for all dog but its our go-to now for trembling dog!

Would definitely recommend for anxious pets...
Well... So far so good. We have a cockapoo and I am sure it helped settle her easier... she was still a bit restless but more able to stay still and not keep trying to hid under everything... So, yes... really pleased so far...Fitted her really well, nice and soft material and was able to have it as a snug fit (which is adjustable)...

Makes all the difference
I inherited a dog that had never been left alone. I am out for a few hours every day. He howled and cried even though there were 2 other dogs with him. He was not in a crate. The thundershirt is working wonders for him. Cries very little if at all. He is just calmer. Under vet direction, I also give him 2mg of melatonin for his anxiety. These 2 things really helped him.

good quality and looks nice!
well made and good fit for medium dog. Basenji cross cattle dog 30 lbs. Velcro at the neck and torso made it easy fit.

Brilliant!!
My Jack Russell x would get very anxious (stressed and shaking) with thunder storms, when insects were in the house, and when having to go to the vet. Before trying anti-anxiety medication suggested by one of the vets, I thought I would try the thundershirt. It’s worked brilliantly. When she gets anxious, the shirt goes on and it calms her right down. She is no longer frightened going to the vets and, instead of becoming reactive (growling and trying to bite the vet), she is now happy to go to her appointments and the vet can give her her monthly injections without any reactive behaviour. In the vets words, they are now ‘BFF’s’! Thoroughly recommend. It may depend on the dog, but it’s worth a try before having to resort to medication.

Best Relationship Saver EVER
The reviews and advertisements are 100% true! My anxious Beagle/Shepherd mix is horrible during storms, and in every day life when his anxiety levels rise. Wearing this shirt for him helps him sleep through thunderstorms. If the noise wakes him, he's not running around the house panting and drooling - he simply raises his head, growls for a moment and curls back up to go back to sleep. During fireworks, he's not running in circles, he's cuddled next to me. This is an amazing product! Last night, I used this shirt on him because I had a rough day at work and knew I would have a restless sleep. All you dog owners out there know that our pets feed off our moods. By putting this shirt on him, he was able to NOT react to my tossing and turning, and as a result, I got a better sleep, even in my stressful mood! The only negative I have is that it seems that the velcro will pull on the shirt material, causing snags, etc. if the velcro isn't carefully applied to the receiving strips. But who cares - the dog doesn't, so I don't :) If I have to buy another next year, I absolutely will!
