Climate is definitely something worth considering before choosing any large breed. Some Molossers handle warm temperatures better than others, but they'll all benefit from plenty of shade, fresh water, and avoiding strenuous activity during the hottest part of the day. Bark Busters https://bark-busters.pissedconsumer.com/review.html definitely know everything about it. Temperament and overall health are just as important as heat tolerance when making a decision. Talking with experienced owners is one of the best ways to get realistic expectations. I hope you find the breed that's the right fit for your situation.
