Random but I got Diesel a cooling mat for his bed and I swear……within a minute of him laying on, the boy is SNORING. If you live anywhere hot, you know how hard it can be for your pups to cool down! I chose this particular one because it is MACHINE WASHABLE! They have many different sizes to choose from and start at only $9! LTKSeasonal LTKPets LTKSummerEdit
