SAVE on the Ruffwear Swamp Cooler - the ideal solution for dogs on the move in hot weather. Available in a range of sizes, the Swamp Cooler will help to keep your dog cooler in the sun for upto 2 hours depending on temperatures and activity level of your pet. Some people think it is odd to put a coat on a dog when it is hot - but like our Cooler or Wet Wrap, this Ruffwear product helps to cool down your dog. Great for dogs on the move, it offers maximum cooling - through both evaporation and heat reflection The light colour is good for sun reflection while the outer layer provides evaporation. Water for evaporation is held in the middle layer while the inner layer has the most important job of all - transferring the cooling effect to the dog. Simply soak in water before placing on your dog. Recommended by many dog owners in USA - where summers are usually much hotter than here! Easy-on and off thanks to side autolock fastenings. Loop for attaching Beacon light. Colour: grey Sizes to fit most dogs. Use the measuring guide in the pictures section to check correct size.
