Simply, just soak the toy in water, when the spongy texture absorbs the water inside the toy and place it in the refrigerator to cool down for a while. The cooling toy offers relief to the dog on hot summer days and also works excellently for puppies to alleviate toothaches. You can also take the floating toy with you on summer swimming trips!
