We are always careful where he is concerned. If I go by the 79 degrees he would never get out of the house. LOL He does pretty well, but I usually let him play in the water while we are outside or go in the pool. We've been out in the boat and if we can stop somewhere we let him cool off in the water too. But the white on his face gets a little pink, so I wanted to put something on it so it doesn't get burned. Thanks for your help.
