I have a lil blue pit that is short legged an he is great in cool or cold weather but not so good in heat he gets hot fast an you gotta watch him because he will strike his own hog so hot weather is not his friend
I'd add on to that and say make sure your dog has shade and lots of water to drink when it gets hot outside. We keep a large bucket of water inside our garage for our labs that they can drink out of when they please. We also have a pond for them to swim in so they stay pretty cool. If it's too hot they'll be in the house or they'll just stay inside the garage where it's cool.
