The Happy Hoodie is a soft, expandable, lightweight, safe and comfortable band that is placed over the animal's ears to provide relief and protection from loud noises and forceful air. Perfect for calming and protecting pets during the force drying process. Unlike cotton balls, pets can't shake the Hoodie off and usually don't try to remove it. Happy Hoodie can also help pets who are frightened by noises in the home or who have long ears that are constantly in their food and water bowl. The package comes with 1 Small 5 and 1 Large 8 inches.
