Hello Christie,
Welcome to the forum and congrats on your two new babies! As everyone has been telling you, there is a huge amount of valuable information here for you to utilize. I am still fairly new but I can tell you that after spending time on this site, my cofidence in knowledge on the breed has boosted greatly!
Here in Arizona, it gets very hot to say the least
!! I keep Duke in a wire crate as they provide much better ventilation than the plastic ones. In addition to that, the crate is indoors where there is AC. If you are going to give them water in their crates, just ensure that you get them out to use the potty as often as possible. Other wise you might be creating an "elimination in the crate" habit. Hope you find the info you need here. Good Luck!!!
