Thermal Pull Cooling Mat™

The mat seems cool to ths touch but im not sure how long for. I didnt like the cooling toy i was unsure of how safe it was for my dog. The mat i felt was expensive and my dog hasnt really used it

One dog loved them the other dog chewed it into bits and the first dog walloped it down, so second dog got nothing.

Mats don't seem to stay cool any longer than the cheaper versions. No laundry instructions - can I wash them or not?
