ThunderShirt Polo Anxiety Vest for Dogs

To get the most accurate size anxiety vest for your pet, measure the girth of their chest, around the widest part of your dog's torso right behind the front legs, with a cloth tape measure. Pull the cloth tape snug, but not tight. If you don't have a cloth tape measure, you can use a piece of string and measure it with a rigid ruler afterwards. If your dog is in between sizes, we recommend that you choose the larger size.

Please use Chest as your main measurement.

Please make sure to measure your pet for the best possible fit. If your pet measures between two sizes, we advise ordering the smaller as this product works through compression.

ThunderShirt's patented design applies a gentle, constant pressure on a dog's or cat's torso. Using pressure to relieve anxiety has been a common practice for years.

For many types of anxiety or fear issues, no training is necessary! Just put ThunderShirt onto your dog or cat and you will likely see results with the very first usage. However, for some, it may take two to three usages to see maximum results. For some more serious anxiety cases, such as severe separation anxiety, you should consult a good trainer for how to integrate ThunderShirt into a training program.

ThunderShirt is made with durable, washable fabric. When necessary, ThunderShirt may be washed in a regular cycle using regular laundry detergent and cold water. Hang to dry.

ThunderShirt is designed to be safe to leave on for extended periods of time when appropriate for the situation or issue. When properly sized and properly put on with a comfortably snug fit, your dog should be very comfortable. If your dog will be wearing a Thunder- Shirt for more than one hour at a time, we recommend removing ThunderShirt every one to two hours during the initial periods to check for any signs of irritation points. Irritation points are very rare, but it is best to be cautious.

We designed ThunderShirt to be very easy to put on your dog and cat, even if she is already in a state of anxiety. It just takes a few seconds and is very easy to adjust for proper fit.

When fitting a ThunderShirt on a male dog, the straps that go around the stomach area should not cover or push on the genitals or prepuce. If the ThunderShirt rubs against the genitals or prepuce, irritation may result. If you see any indications of this, remove the ThunderShirt immediately. Try a smaller size or contact us for other suggestions.

Except in extreme conditions (e.g. 90 degrees Fahrenheit in the sun), overheating is not typically a concern when using a ThunderShirt. Dogs cool themselves primarily through their mouths and paws, and a ThunderShirt is constructed of a thin, breathable fabric. But if you feel that overheating might be a problem for your particular circumstance, please monitor your dog for any signs of overheating such as heavy panting or tongue hanging out of the mouth. Remove the ThunderShirt if you see any signs of overheating.

Most dogs and cats love to wear ThunderShirts! 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.
