<- big furries + anything above 75 (well to be really honest 50) degrees + anything above 40% humidity = hot slobbery doggies! I run the AC for them but also for me because the humidity gets to me. I grew up in Upstate New York where it was only super hot 3 wks out of the year, so I guess I never developed a tolerance. My 2 yrs in CA I was out mtn biking in 90+ degrees and was fine- but sweating works out there. Here I just sweat continuously since the sweat can't evaporate into the air and get heat exhaustion very easily. I have been known to stay inside on the trainer because it's too hot.
