I live in Nevada, and last week we hit 117 and we are suppose to be over 110 for a while and one thing i did was to freeze up some plain yogurt, cottage cheese, and some of their other fav snacks and give it to em in the hottest part of the day. My 4 REALLY enjoyed that! I also took to physically "hosing" em down. One other thing i found that worked well to was to add electrolytes to their water as well as about 1 tablespoon of ACV to every gal of drinking water. The ACV is because i found that they have a tendency to eat less in hot weather and it helps em to absorb more of the nutrients of what they do eat.
