Pets are often scared, upset and disagreeable with the deafening noise and high pressured air associated with force drying. Happy Hoodie MUFFLES THE PAINFULLY LOUD NOISE and keeps the high-pressured air from getting into their ears. Happy Hoodie has an almost IMMEDIATE CALMING EFFECT which greatly IMPROVES BEHAVIOR! A calmer pet makes for a safer environment and saves us A LOT of time and frustration with the drying process. It only takes a few seconds to put on and what a HUGE DIFFERENCE it makes!
