 You know, it's a tough deal, and a lot of it's knowing your dog, knowing what to look for, you know, looking at their tongue, looking at the way they're breathing, their eyes, that kind of stuff. You know, as soon as you see that tongue really starting to curl, it's kind of my first watch out that, hey, this dog's getting pretty hot. Boy, you know, you stick your finger in their ear sometime when they're that hot, it almost feels like it's cooking your finger. It's amazing how warm they get, how quickly.
