Banded Standard Dog Parka, Extra Large, Bottomland Camo-00930. 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 Neoprene Dog Parka traps your dog's body heat helping his/her coat dry faster while reducing energy zapping shivering. It also provides floatation and protection that your dog needs to perform its important job for you.
