I dont know if I have that brand..but I have some kind of cool down mat that you soak in water... dog hated it... pretty soon they were just laying in hot water..since I got mine I have seen feedback from others that felt the same... anyhow, that was my experience.. dunno what they cost, but I would sell mine that is hardly used for 25% of whatever a new one costs plus shipping..
I have one, but I don't know what brand it is. I use it. It works okay, but I don't know if it really gets that cool. I am not going to buy a new one for my new pup. I figure, since i am in La. where it's nasty hot all summer, it can't hurt.
Take an empty 2 liter bottle, fill it 3/4 with water, cap it and freeze it. Put that, wrapped in a towel in the crate with pup. Make sure pup's not a towel eater. When it thaws, pour into bowl for pup or drink it!
