Traveling with the Pooch

Am trying to figure out different ways to keep the Chevy doggy comfy when we hit the road.

Temps are going to be climbing up there pretty soon.  Got to prepare for it.  Not good to leave doggy's in cars in high temps, bad for doggy's. 

So far my ideas are to avoid stopping in big cities and touristy traps, sticking mostly to nature and state parks type of places, where she is welcomed.  Will also wait to do any grocery type shopping til later at night once it's cooled down some.  A windshield shade, front windows rolled down some, back side windows opened for cross ventilation, a 12v fan and water close by.  Have considered leaving it running with the A/C on and locking it, taking the spare keys inside.  Or, getting her a vest as a service dog and going only where she is welcomed. 

Will be trying out a few times this week, at different temps, the above mentioned scenario with the shade and fan and windows cracked and seeing for myself at what temps outside it reaches inside and at how many minutes it takes to reach what temps.  Maybe I should look in to getting one of those thermometers that you put inside and also gives you an outside reading with a small hookup outside.  Would be helpful on my trips. 

Other alternative is to beg Hotrod to let her hang out with him...  okay, continue to boss him around like she owns the place, haha.  Last resort, as she loves taking off in Van Halen.  But whatever route, gotta take care of lil doggy!!!
