Review: Noticeably helps calm anxious dogs during storms and stressful situations - The ThunderShirt calming vest works surprisingly well for helping dogs relax during stressful events like thunderstorms, fireworks, or travel. The snug, gentle pressure from the wrap-around design seems to have a soothing effect, similar to how weighted blankets work for people. After putting it on, my dog became noticeably calmer and less reactive to loud noises and sudden sounds. The material feels durable but soft, and the adjustable straps make it easy to get a secure fit without making it too tight. Once adjusted properly, it stays in place and allows the dog to move comfortably without restricting normal activity. The bright fuchsia color is also easy to spot and looks great. A helpful tip is to introduce the ThunderShirt during a calm moment first so your dog becomes familiar with wearing it before a stressful event. It also helps to adjust the straps so the vest fits snugly but still allows comfortable breathing and movement. Overall, this calming vest is a simple and effective tool for helping reduce anxiety in dogs during loud or stressful situations. Review: 100 % WORTH IT! - Great for anxious dogs. I have a 8 year old Chipoo (Prince) and a 2 year old Chiweenie (Leia) who are both very anxious in their own ways. Prince has bad separation anxiety and Leia is scared of loud noises like fireworks/thunder. They both seem to be more calm after I put on their vests. When we leave them alone I watch them through a doggie cam and Leia just sleeps and Prince lays down and watches out the window. Prince would howl and lick the window before and that has stopped now (with the vest). It also helped Leila tremendously with christmas/new years fireworks. I did also combine these vests with the Thunderease diffuser so I definitely recommend both products. Quality is good, Prince is 10.8 lbs and i got him the XS and Leia is 8.8lbs and she got the XXS. Both fit great. Prince also got the sport version so it’s different material and less stretchy than the original. The jump from XXS to XS is also a bit drastic as you can see in the photos, the sport version seems to be made for bigger breed puppies so I would say stick to the original for smaller breed dogs. I put them on pretty tight and they are still able to move/run like they normally would. ## Features - ThunderShirt is the #1 vet recommended calming wrap & already used by millions of dogs to help calm anxious behaviors! - Our patented*, easy-to-use calming wrap for dogs is a drug-free option which applies gentle calming pressure around your dog’s torso, similar to swaddling an infant. - Use ThunderShirt whenever your dog experiences anxiety in situations such as thunderstorms, fireworks, vet visits, separation, loud noises, traveling, and having visitors. - Over 85% of pet parents surveyed reported improvement in their pet’s signs of stress when using ThunderShirt. - ThunderShirt is light-weight, breathable, and machine washable, fit for all climates and lifestyles.

She also has separation anxiety. I purchased this in an xx small and it fits good. While I was out, it started to rain and thunder and lightning today. Immediately came home and put it on her as she was panting and jumping in my lap and jump out, pant and shaking! I put it on her as tight as I could get it. She still seems nervous, but the panting stopped and she is not shaking as bad. So overall, it’s a great buy and does work. ## Frequently Bought Together - ThunderShirt for Dogs, X Large, Platinum Sport - Dog Anxiety Relief Calming Vest - ThunderEase Dog Calming Pheromone Spray | Powered by ADAPTIL | Reduce Anxiety During Travel, Vet Visits and Boarding - Purina Pro Plan Veterinary Supplements Calming Care - Calming Dog Supplements - 30 ct.
