The Thunder Shirt applies gentle, constant pressure around your dog's torso, which has a dramatic calming effect for most dogs if they are anxious, fearful, or over-excited. Over 85% of dogs show significant improvement in anxiety symptoms when using Thundershirt. Recommended by thousands of veterinarians and dog trainers.
As for why Thundershirt's gentle pressure works to calm a dog, experts such as Dr. Temple Grandin believe that pressure has a calming effect on the nervous system. Using pressure to relieve anxiety has been a common practice for many years. For example:
Tellington Touch (TTouch) dog trainers use pressure to address a wide variety of anxieties
Veterinarians use pressure to relax cattle when they are administering vaccinations
People with autism use pressure to relieve their persistent anxiety
Children with certain behavioral problems use pressure shirts and weighted vests to relax and focus
Parents use swaddling to calm newborn infants

How to Put the Thunder Shirt on Your Dog
Thundershirt has been developed to be very easy to put on. Just lay it over your dog's back and secure with the chest and torso straps. The Velcro fasteners make Thundershirt very adjustable to many different body shapes.
1. Place the Thundershirt on your dog's back and wrap the Short Flap under the torso.
2. Wrap the Long Flap under the torso and secure with Velcro onto the short flap. Make a comfortable, but snug, fit. You should be able to easily slide your fingers between the Thundershirt and your dog's torso.
3. Wrap the Top Flap down onto the Long Flap and secure with Velcro. Adjust to improve the snug fit and keep Thundershirt securely in place.
4. Wrap the Chest Straps around the front of the dog and secure with Velcro. You should be able to easily slide your fingers under the Chest Straps and should not feel restricting around your dog's neck.
How To Use Thundershirt
Thundershirt is an excellent treatment for most types of dog anxiety and fear issues. For many anxieties, such as noise, crate, travel, barking and others, just put the Thundershirt on your dog and you will likely see results without training. For more complicated anxiety cases, we recommend using Thundershirt as part of a behavior modification program.
Thundershirt is also a useful tool for managing excitability or hyperactivity with strangers, on a leash, or in a training environment. Thundershirt's calming effect can help your dog to focus (or refocus) his energies in a more constructive direction, allowing training to be more effective.
Introducing Thundershirt to Your Dog
Before putting Thundershirt on your dog for the first time, we recommend offering a small amount of food to your dog using the Thundershirt as a "plate". Dogs typically become more comfortable and trusting of something that "brings" them food or anything that they associate with food. So this is an easy little trick to quickly create a positive association with Thundershirt for your dog.
Washing Instructions
Thundershirt is made out of durable, washable fabric. When necessary, Thundershirt may be washed in a regular cycle using regular laundry detergent and warm water. Hang to dry. To remove dog hair from Thundershirt's velcro, try using a standard dog "slicker" brush. A couple of strokes and the velcro hooks will be nearly completely hair-free.
FAQ: Is overheating a concern when using a Thundershirt?
Except in extreme conditions (e.g. 90 degrees Fahrenheit in the sun), overheating is not typically a concern when using a Thundershirt. Dogs cool themselves primarily through their mouths and paws, and a Thundershirt is constructed of a thin, breathable fabric. If you feel that overheating might be a problem for your particular circumstance, monitor your dog for any signs of overheating, such as heavy panting or tongue hanging out of the mouth. Remove the Thundershirt if you see any signs of overheating.

My dog has started to have extreme anxiety when my kids come over. He gets so excited he has seizure like activity while here and exhausts himself. This vest has been very beneficial in calming him enough to not exhaust himself, but he still does it (turns in circles, snaps at the air, seems to be seeing something that's not there) I am going to consult his vet also, but the vest has helped a lot! Thank you!!

Sky has always been afraid of storms, usually found in a closet or under a bed. My ex wife bought her a cheap version at PetSmart which helped very little if any. She did report this one helped, but she still shivered the whole time, but at least was not terrified.

She is severely afraid of storms and night time starts shaking panting scratching and does everything she can to get out of the house. We got her the Thundershirt. It has done wonders for her. It does not take her anxiety away 100%, but I would say about 90%. She now will lay down by my feet and does not stress as bad. I'm glad I got this product. Makes for less sleepless nights.

I have been so surprised with this shirt. My dog would shake all over and hide under something every time it started to thunder. Loud noises would scare him badly. I was afraid he was going to have a heart attack or something it was so bad. With the thundershirt, he is much calmer. He still will have a small tremor, but nothing like before, and he does not hide under furniture anymore. The shirt has not completely cured the problem, but has helped my precious little dog so very much. He now comes to me to put it on him if he hears thunder.

The shirt does not alleviate all of Lucky's anxiety. He still does his stress-panting. However, when it begins to thunder, he absolutely cooperates when we go to put it on him. He approaches and stands real still as we put it on him. It does seem to be at least somewhat comforting to him.

Couldn't get it on my dog. He has serious issues. Ge is a rescue I got. He was beaten badly and is very fearful of humans. He does fine around other dogs but not people. I thought this product might help, but he gets too scared when he even sees it.

Zeus is afraid of everything. We had to take the wind chimes off our deck and his own shadow is his biggest nightmare. We tried the Thunder Vest and it worked in that he wasn't afraid anymore, however, this lack of fear instilled in him an instant feeling of thrill seeking. Every time we opened our front door Zeus would charge out of it, ready to take on the world and then we'd have to chase him down. We opted to remove the vest, better that he stay at home and fear the wind than charge dangerously at a semi truck.

I purchased the thundershirt for my beagle mix because she has seizures. She shakes violently from these seizures & we couldn\\\'t do anything to comfort her. With the thundershirt, her seizures, although not gone, have lessened in severity by more than 50%. It\\\'s amazing. She loves it and we love it. I would recommend this to any dog owner whose dog has problems. 5 stars!!!!!

My dog would tremble with fear everytime a storm was brewing, even thunder off in the distance would make him tremble with fear. I put the vest on him and it calmed down his trembling by about 90%.
He still trembles during a storm but with the vest on, not nearly as bad! Only problem I have is that when my dog is wearing his vest he shakes his body all the time, as if he is trying to shake it off and this drives me crazy, it is so annoying! But when I take the vest off him, he stares at it and whines, so I lay it in front of him and he is not happy until I put it back on him. Just don\'t get it.
However I would totally recommend this vest, well worth it.

My dog Jack has always been seriously afraid of thunder. He tries to get out of the house and has injured himself and damaged the house trying to do so, if we are not around when a storm comes up. The Thundershirt is not a miracle, but it has really helped. Since we began using it, Jack has been much, much calmer. Staying near me quietly during all but the very loudest thunderstorms -- he even stayed very calm through Hurricane Irene. He really seems to like wearing it. When I suggest putting it on, he comes and waits for me to get it on him. I strongly recommend this product. Also, for those who say it didn\'t magically fix your dog\'s aversion to fireworks: Don\'t take your dog to fireworks!

The vest was a gift to one of my daughter's dogs. Buffy is terrified of storms and can sense/smell them when the sky is blue, no clouds in sight. My daughter has to hold her and hug her during storms with only moderate success. The dog is a real thunder chicken.
