The summer heat can be dangerous for all dogs but some are more susceptible than others - the "winter" breeds - the dogs with long thick coats - Huskies, Akitas, Malamutes, Chows, etc..
The dogs with short snouts - Boxers, Rotties, Bulldogs (Frenchies, English, etc..); the very old and the very young.
Also be extra cautious if your dog has white fur or very short fur or pink skin. These dogs can sunburn easier than other dogs (any dog can sun burn)
Watch for signs of heat exhaustion like excessive panting. Some dogs will tell when they are tired. If your dog stops all of a sudden during play or walking, listen to him or her. It's time to go inside and rest. But note that some dogs will not know when it's time to quit. They will keep going just to please you. You will have to know when it's time to take a break.
Be very careful taking your dog out in the middle of the day (avoid it if possible). Pavement can get very hot - can even burn their sensitive little feet.
If your dog is mostly outside, check his/her water source often. The water can become hot very fast. Put out some ice cubes often to keep the water cool. Make sure the dog has plenty of shade and/or a dog house. Of course, living inside is much better especially during extreme temperatures.
Most garages will not provide suitable housing for our Big Dawgs. Most are not insulated and the temperature can be just as extreme as the outdoors. Maybe even hotter if there is no ventilation.
If your dog hasn't been exercising much - now it not the time to start a jogging regimen. Dogs have to slowly get into shape just like us humans.

Interesting note - according to the above article, a wet dog can become overheated. The water can heat up on the fur causing a "sauna" effect.
