Like swaddling an infant, ThunderShirt applies a gentle, constant pressure to your dog’s torso. Research on both humans and animals suggests that this type of pressure can release a calming hormone like oxytocin or endorphins. This calming pressure is helpful for over 80% of pets. Results are likely with the very ﬁrst usage. However, for some, it may take multiple usages to see maximum results.
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 and try a smaller size.
