The first couple of nights Koda hated his crate, however since I found this cooling pad he has been all about his crate. I haven't been able to get him out of his crate since I put it in there!

I'm guessing that you meant this pad.  Did you also get the cover to go along with it?

It looks like this, btw:


Which size did you get?  Looking at the sizes and my pups crate sizes it looks like a large would be better ....?

I'm not sure about spending money for something to keep my dogs cool - since they'll lay out in the sun until the temps approaching 100° but then again it really does look like a "cool" option.

Yes that is the one, I did not get the cover I was waiting to see if he liked it before I committed more money to it.

I went with the medium to fit his puppy crate. Koda isn't liking the Texas heat, even though it changes daily LOL.
