Cooling mat for dogs ideal for your pet's well-being! The Penguin cooling mat for dogs by Croci is a delightful self-cooling mat for dogs in the shape of a penguin. Ideal for keeping your dog cool during the summer. It is made externally from a mix of polyester and PVC, and inside there is a water-based and completely non-toxic gel. How does the cooling mat for dogs work? Thanks to the pressure generated by the animal's body and the gel inside, the cooling mat cools and regulates the animal's body temperature in a constant and continuous way. This technology manages to keep your favorite puppy 7-9 degrees below the ambient temperature.
