Hot days can be made a little more comfortable with the addition of a cooling collar! The cooling collar is a blue Velcro collar with a gel pocket. The collar is 23.5 inches in overall length, and 1.5 inches wide. The gel pocket is centered on the collar. The gel area is 11 inches long, 2 inches wide, and about 1/2 an inch thick. To use, refrigerate overnight, then Velcro it low on your dog’s neck. A separate buckle or correction collar can be used higher on the dog’s neck while the dog is wearing the cooling collar. Avoid puncturing the collar. Discard immediately if punctured.
