Overall, there is some evidence that the ThunderShirt can help with anxiety in dogs, but the studies are small and few in number. They are easy to use and any results are almost instantaneous.

The effect is similar to swaddling an infant, or using a weighted blanket for adults. Studies have shown that the constant pressure can actually help to reduce an elevated heart rate, which is one of the reasons the ThunderShirt helps dogs and cats to feel calmer.

ThunderShirt® is the original, vet recommended, natural calming solution that may 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.

When sized and put on properly, your dog or cat should be very comfortable wearing a ThunderShirt. Problems are very rare, but if you see any signs of skin irritation or physical discomfort, please discontinue use and contact us.

How long can a dog wear a thundershirt? The Thundershirt can be left on for extended periods of time. However, the first few times of wear, it's best to remove it every 1-2 hours to check for any signs of irritation. If using the Thundershirt for extended periods, it is recommended to remove it at least twice a day.

There have been no side effects. However, some dog owners have reported vomiting, diarrhea, incoordination, and convulsions.

The ThunderShirt has also been demonstrated to help lower signs of anxiety and fearfulness in dogs under simulated thunderstorm conditions. Dogs wearing the thundershirt were less likely to hide or display behavioural signs of anxiety.

One study found that dogs who had not worn a ThunderShirt before experienced an increased heart rate shortly after putting it on. Once they habituated to it, though, their heart rate decreased, and they showed fewer signs of anxiety, such as lip licking, yawning, and staring at the door from which their owner exited.

ThunderShirts are recommended by veterinarians and veterinary behaviourists as a tool to help with treating common fears and anxieties including storm phobias and separation anxiety.

The Science Behind Weighted Anxiety Vests Studies have found that this pressure can help stimulate the release of oxytocin, which can help reduce anxiety and lower heart rate. It is essential to note that weighted anxiety vests might not work for every dog or every anxiety-triggering situation.
