Why should your dog wear one? Because of body heat. Your dog begins to lose crucial body heat sooner than you might think. Water temperatures below 55°, sub-40° air temps, and 20 mph winds are prime conditions for deadly canine hypothermia to occur. A Boater's Dog Parka traps your dog's body heat helping his coat dry faster while reducing energy zapping shivering. It also provides flotation and protection that your dog needs to perform its important job for you. Convenient handles located on the back of the parka allow you to pick up your dog with ease.
