Be aware of the signs of heatstroke
Pets can get caught up in playing and exploring outdoors in the heat which can lead to overheating and heatstroke if you are not careful. Be on the lookout for sudden changes in behavior and physical traits including lack of obedience, an overly warm body, labored breathing, a distant or worried look, vomiting, and a faster heartbeat.
If you notice any of these signs and think your pet might be overheated you can try to lower their core temperature by applying towels soaked with cool water or finding a cool spot where they can remain inactive for a while. If they are still acting as if they are uncomfortable after a little while in a cooler environment, then it is best to take the dog to your vet.
Be particularly careful if your dog is a breed that is more likely to overheat like Bulldogs, Boston Terriers, Boxers, Pugs and any other short-nosed breeds.
