The dog days of Summer have arrived and I'm looking for the latest way to cherish (and cool off) my hot dog – I think I've found just the thing! The new iCool Pet Mats ($25) come in two colors (blue and pink), two shapes (rectangle and oval), and two sizes for those pets large and small. When I first spotted this product I thought it was a gigantic ice pack but, turns out, you just add water and an absorbing polymer creates this soft, gel-like mat to keep pup cool – no refrigeration needed!
