Thundershirts Sport for Dogs wraps around your dog to provide a gentle hugging feeling to calm them down. With their patented design, the constant pressure that the shirt creates has a dramatic effect on most dogs when they are overexcited, scared, or anxious. According to ThunderWorks, in a survey completed by over two thousand customers, over 80% of dogs and cats showed significant improvement in their symptom when using the Thundershirt.

So how does it work? Experts believe that the pressure that the Thundershirt creates has a calming effect on the nervous system, possibly by releasing endorphins (a calming hormone). This is why using pressure to relieve anxiety in people and animals has been a frequent practice for many years. Examples include parents swaddling infants, veterinarians using squeeze chutes when vaccinating cattle, and thousands of people with autism using pressure to relieve persistent anxiety.

Use Thundershirt Sport for:

Fear of thunder, separation anxiety, reactivity, barking problems, car or travel anxiety, general fearfulness, any excitability, leash pulling, any noise anxiety, crate anxiety, and more...

Instructions for Thundershirt Sports

Thundershirt Instructions

Step One

Place the ThunderShirt Sport on your dog's back and wrap the short flap under the torso.


Step Two

Wrap the long flap under the torso and secure with fasteners onto the short flap. Make a comfortable, but snug, fit. You should be able to easily slide your fingers between the ThunderShirt Sport and your dog's torso.


Step Three

Wrap the top flap down onto the long flap and secure with fasteners. Adjust to improve the snug fit and keep shirt securely in place.


Step Four

Wrap the neck straps around the front of the dog and secure with fasteners. You should be able to slide your fingers under the neck straps and should not feel restricting around your dog's neck.


Wearing ThunderShirt Sport for Extended Periods of Time: Thundershirt Sports are designed to be safe for your dog to wear for extended periods of time when appropriate. When properly sized and fitted with a nice comfortable snug, your dogs should feel very calm and comfortable. If your dog is wearing the Thundershirt Sport for more than a couple hours at a time, we recommend removing the shirt periodically (at least initially) to check for any signs of irritation. Though it is rare for irritation to occur, it is better to be safe.
