Until now, there just hasn’t been a well-designed, inexpensive pressure wrap commonly used for dog anxiety. Thundershirt is changing that! Thousands of veterinarians and dog trainers now recommend Thundershirts for their anxiety cases.

Thundershirt is an excellent treatment for most types of dog anxiety and fear issues. For many anxieties, we recommend just putting on a Thundershirt and observing the results (No training!). You very well may see significant improvement for noise, crate, travel, barking and others with absolutely no training. For more complicated anxiety cases, we recommend using Thundershirt as part of a behavior modification program.

One thing is for certain, for a very large percentage of dogs, Thundershirt’s gentle, constant pressure has a terrific calming effect. This has obvious benefits for most types of anxiety. But Thundershirt is also a very useful tool for managing excitability or hyperactivity with strangers, on the leash, or in a training environment. Thundershirt’s calming effect helps a dog to focus (or refocus) her energies in a more constructive direction, allowing training to be more effective.

We hear skepticism all the time."Why would a shirt help my dog's anxiety?""Is the fabric infused with a drug or does it contain magnets?"

All we can say is ...Thundershirt's gentle, constant pressure has a dramatic calming effect for most dogs.  We can't say exactly why it works because scientists haven't figured it out yet, but Thundershirt is already helping tens of thousands of dogs.

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.

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. See the illustrations and video for more information about how to put Thundershirt on. Or click here for the instructions included in the packaging.

	Step 1 Place the Thundershirt on your dog’s back and wrap the Short Flap under the torso.
	Step 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.
	Step 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.
	Step 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.

What if Thundershirt isn’t working for my dog?

We stand behind our product. Thundershirt is a terrific solution for most dogs suffering from anxiety. Many owners see reductions or complete elimination of symptoms with the very first use. With others, it may take two or three usages of Thundershirt to see results.

 But if for any reason Thundershirt isn’t the right solution for your dog, return it within 45 days for a full refund of your purchase price.
