Well Dinah I remember something that I read a few years ago,....took me a bit to recall this, but I read about a team of sled dogs from way up north that were being flown to some destination for whatever reason and the flight had a stop in Miami....I'm thinking this was in cooler weather, however their flight was delayed for a few extra hours there in Miami. The temperature got up to 80 degrees and 3 or 4 of the dogs died from heat stroke. Soooooo, I guess you were right about it making a difference, of course this was somewhat to the extreme, but it apparently mattered to those dogs.
Sounds like good scientific evidence to me. I was wondering since it seems like we deal with extremely hot days more than cold ones. A lot of dogs die every year from over heating and it would be nice if we could figure out a way to breed heat tolerent dogs.
