Do Thundershirts Really Calm Dogs During Fireworks or What?

The dogs will lose their intellects. They always do. Every Fourth of July in America, as children stay up past their bedtime to watch colors explode in the sky and adults sit on the back of pickup trucks drinking beer and marveling at a pyrotechnic technology 12 centuries old, pets across the country panic with every boom.

Sound phobias are very common for dogs–and cats–making this holiday a nightmare for millions of animals. “Half of the dogs in my practise are dealing with fireworks fear this week, ” says veterinarian and animal clinical behavior resident Amy Learn, whose clinic in Richmond, Virginia, insures more than 2,000 clients annually. For many dogs, the nightmare has already begun. A quick search on Twitter proves people across the land complaints about neighbours popping fireworks off early. In Boston, where I live, they first started exploding in the middle of last week. The German shepherd next door has been pacing back and forth every night since, nails skittering across the floor.

That behavior is typical for puppies with loud noise phobia. Learn says you’ll know if your animal has abnormal fear of loud voices if they don’t recover from the initial shock of hearing the sound right away. If your puppy is pacing, howling, panting, and trying to run as far away from the sound as possible; if your cat is hiding, its ears cocked back, its eyes distended, they need help. Every year around this date, people flock to Google to search “How to keep a dog pacify during fireworks.” One answer that frequently shows up at the top of the results: nervousnes shirts or thunder vests.

These come in two main designs–a spandex T-shirt that’s meant to give an animal a balanced hug, and a vest with straps designed to put pressure on particular areas of the body. “Their job is to squeeze, ” Learn says. “It’s postulated that it feels like a hug.”

Animal anxiety shirts were immediately inspired by research into humen with severe nervousnes or autism. The insight that certain kinds of touch and pressure can have a calming effect was first popularise and championed by livestock behavior expert and autism-awareness-advocate Temple Grandin, who devised a “hug machine” for humans with autism after noticing the route a light squeezing soothed kine before carnage. Grandin’s work is specifically called out on the website for Thundershirt, the major player in the animal nervousnes wrap market. Deep Pressure Therapy is now widely used to help calm people with autism, and many different studies suggest the therapy presents real results.

But the science is less clear about whether pressure therapy really works for dogs.

Michelle Mullins, an animal behavior expert and board member of the International Association of Animal Behavior Consultants, first learned about animal anxiety shirts two decades ago. But they have only gone mainstream in the last 10 years with companies like Thundershirt. “As we often are wont to do when we look at science, we want to say if it works for humans it will work for our pets. In some examples it’s true and in many cases it’s not, ” Mullins says. “Unfortunately we don’t have a huge amount of scientific studies about this.”

There’s only been one study to date into the use of anxiety shirts to deal with sound phobiums, and it had a small sample size of 18 participants. Published in the Journal of Veterinary Behavior in 2013, the study compared owner-reported anxiety levels before and after prolonged utilize of anxiety wraps, and found that 89 percentage of dog proprietors felt the shirts helped. Most importantly, the study found that even for those working animals who considered no benefit, there were no adverse side effects. But one examine is hardly conclusive evidence, and along with small sample size the study is also hindered by relying on self-reporting, which frequently highly unreliable.

That leaves pet owneds and people who care for animals to depend on anecdotal experience. “This is one of those things that isn’t super scientific, ” says Learn. “A lot of it is subjective. It’s the owner saying,’ Oh, my puppy feels better.'” But owneds apparently feel that way a lot.

“I rarely if ever recommend them as a cure all, ” says Mullins, “but I have considered many puppies successfully use these as part of their therapy.”

Both Learn and Mullins report working with animals that appear to be helped by these shirts. They always recommend owners use the shirts in combination with other interventions, like medication or specific behavioral adjustments. A hallmark of Mullins’ long-term behavioral work with sound-phobic animals is to desensitize the animals by uncovering them to loud voices slowly over hour. Clearly, for people searching Google for a answer in the working day before the Fourth of July, it’s too late for that. For them, an anxiety shirt may be the easiest option this year. You can get them speedily, and put them on your animal immediately.

Learn often suggests that people spray “dog-appeasing” pheromones on the anxiety shirts, a therapy that has been more widely studied–though its effectiveness is still up for debate. One study indicates dog-appeasing pheromones can pacify canine noise-associated anxiety, but two others were inconclusive. Learn reports that she has treated pets who have separation anxiety with merely pheromones and observed they worked well.

These results, of course, are also subjective. “It’s hard to say to a pet,’ Are you calmer ?’ ” says Learn. Neither anxiety shirts no pheromones is a “golden pill that solves all problems, ” she adds.

But Mullins and Learn emphasize that here’s no harm in trying them. Neither has find any adverse effects, unlike popular anti-anxiety medications–which can cause increased heart rate, lethargy, more stress, and vomiting. The worst that happens with thunder shirts is that animals find it annoying to be dressed. “These are not a miracle pill that you put on and all your problems are solved, ” says Mullins. But if you know your dog is going to be scared during Fourth of July, one of these shirts or vests might help.

A few other things you can do to calm your dog down? First of all, says Mullins, be smart: Don’t bring your dog to the fireworks BBQ. If possible, remove them from anywhere the noise will be particularly loud. She indicates you turn on a fan or a white noise machine to help drown out the explosions. Give your animal something to confuse them from the noise, like a kong toy filled with food. Give them a safe space like or a crate or a closet where they can hunker down.

And the good news is when it’s all over, and the sky has run darknes and the air smells of potassium nitrate, you have the experts’ blessing to go ahead and give your dog a real, actual, comforting hug.
