I know what you mean. Given his druthers, Krypto prefers to be up with us, unless it's in the 100's out. Then he lies on the cooler floor, close enough to see us, of course. No one walks out of his sight without him following! I'm assuming that your house temperature is generally cooler than mine.
Where you go, so goeth the pups!
