Wow! Thanks for that...didn't know! It didn't cover her whole back as small guest towel size...did seem to stop her panting though! Will look into this more. She won't lay on a wet towel or cool pad. Dave tells me to leave her as she knows when she is too hot, but I think she is daft! We put sun cream on her as she is white, hard to keep her indoors when we are in and out with doors open...
