Oh no, those poor dogs!
I live in St.Louis so humidity gets really bad here.
Besides Ray Ray, I also have a Great Pyr and a Saint Bernard..both heavily coated dogs. But, I never shave anything other then their bellies. I just keep them brushed and combed out really well each night and they spent what time they want inside. Outside, there is always access to shade and water (Lots of trees in the back yard). Needless to say they both would rather be inside anyway.
Not this summer, but the summer before that, there was a huge storm that took out power from more half the people in St.Louis. It was a huge deal, because the power would take up to a week to return to most places.
Durring those times, the Humane Society was one of the lucky ones to keep their power, so they set up an emergency station where pets suseptable to the heat (It would reach close to 100 on some days) would have a place to cool down. From what I understand, they kept it open 24/7
I only had my Pyr at the time, so I brought him in to cool down and they offered him a shave-down. That is the only time I ever had him shaved.
It was a madhouse, with people scrambling for ice from any place they could grab it. We drove miles and miles for ice. Grocery Stores all lost produce, meat and dairy. We had no electricity for 5 days but some where out for close to 2 weeks, in the dead-heat of the summer.
Other times durring the summer, I normally just shaved down bellies. It seems to feel good to lay in the cool grass because I can look outside to check on them and that's what they all do..find a nice bit of shade and lay down, belly flat..lol
