We used to live in N.CA where summers average between 95 & 105 degrees...agh, hot!! Here's what we did:
-my pups stayed indoors (in AC) most of the day
-they exercised in early AM or late PM when it was cooler
-we installed an evaporative cooler & a chain link kennel in our garage so that the dogs could stay in there if we had to go out for the day (the dogs were paper trained)
-planted lots of trees & put up other shade structures
-hooked up one line to our auto sprinkler system to auto fill the dogs kiddie pool every few hours
-hooked up a 2nd line to their water bowl to auto fill also
I haven't tried clipping any of our dogs for summer heat problems. It generally isn't recommended, because their undercoat acts as an insulator to keep out heat in summer as well as keep it in during winter but I know that some people swear that clipping helps keep them cooler.

I'd be very hesitant though to try it. Pyrs skin is mostly pink (with adorable black polka dots that I love, but I digress

), so they would sunburn badly.
If one of your bedrooms with AC has an attached bathroom with a tile floor or shower, Jenny will likely attach herself firmly to that tile & snore for the hottest part of the day.

That was my Cara's favorite spot, anyway! LOL
