I got my NN because they could handle the TX heat. We have more humidity than AZ, but as long as I have provided shade and water for cooling they do fine. I have wading pools (2'x3x8" plastic storage containers) with pieces of concrete that I fill with about 2" of water. They drink it and stand on the rocks or in the water. I pour the poopy water after diluting it on my plants. When we get over 100 on a daily basis, I will take out frozen gallon jugs of water and place it in the shade then dampen the ground. They will lay by the ice jugs during the peak of the heat. I really love how sturdy the NN are.
Here are two of my girls, they all look alike.
