Great for all types of anxiety


ThunderShirt is the original widely veterinarian and trainer recommended and used natural calming solution that helps reduce anxiety in dogs in a drug-free way. Like swaddling an infant, our dog anxiety vest's patented design applies gentle, constant pressure to calm all types of anxiety, fear, and over-excitement issues in dogs. ThunderShirt helps to calm in over 80% of cases, and is recommended for thunder, fireworks, separation anxiety, travel and vet visits.

ThunderShirt applies gentle constant pressure to the torso, which can have a dramatic calming effect. The pressure releases a calming hormone like endorphins or oxytocin and can reduce heart rates, stress hormone levels, and many other observable anxiety symptoms.  

The patented hook-and-loop fastener pattern on the neck straps will keep the straps from flopping.

Make the ThunderShirt fit is comfortable and snug and you introduce it to your dog during a time of no stress.

When properly sized and put on, the ThunderShirt can be left on for extended periods of time. However, during the initial uses, confirm that there are no issues and check for signs of discomfort or irritation. Do not leave on for more than 1-2 hours and remove the ThunderShirt at least twice a day.


  • Material is lightweight, machine-washable, and breathable
  • ThunderShirts have frequently been referred to as thunder jackets, thunder vests, and thunder coats – if that is what you are looking for, you are in the right place!

Makes a Huge Difference to the Anxiety Level

Having read the reviews on this item, purchased to see if would help our 4-legged whom suffers anxiety at the first sign of thunder, lightening and hail with heavy rain.
Highly recommended, in fact our boy would rather keep it on but it can only be worn for consecutive 2hours at a time by which time the wet weather may have subsided.

Thanks so much for the review, so glad it's working so well for you. We use one as well and notice the difference.

Good news though: the 2 hour limit is only the first few times to make sure it fits right. This is from the Thundershirt website:
'Most people say that their dogs and cats really enjoy wearing their ThunderShirts and they are safe to leave on for extended periods of time depending on the issue. But, please note! We recommend removing ThunderShirt every one to two hours the first few times to be sure everything is fitting correctly and your pet is happy. Irritation or other issues are very rare, but it’s always best to be cautious. AND, always remove the ThunderShirt at least twice a day if using for extended periods.'
