Don't bring dog
Scenery on the way out from Albuquerque was awesome! I'd definitely go again, but only if I have an RV w/AC (see below)
Cons: I was down for a dog show and had a rental car. It was my last day, so had checked out of the hotel. They don't allow you to take your dog to the Sky City because there are loose 'local' dogs up there. No place to leave the dog in the car without risk of overheating, since there's no shade.
