I don't know, I tend to think that if a dog was that uncomfortable w/ it, they wouldn't want to walk on it. I mean I wouldn't do long periods of time walking on super hot pavement, but for the most part, I think dogs know themselves well enough. I can tell when Jackson is too hot in general because he may stop a bit, or slow down, etc, but if he seems happy and content to keep swimming/jumping/running, I let him. Maybe some booties if you are really concerned? But paw PADS are there for a reason... they're like dogs versions of shoes (it's not equivalent to our hands or feet touching it), and while in certain extremities, booties or other protection may be needed, for the most part I think their paws can handle more than we think with just some common sense.
