Summer heat can be dangerous for dogs the same way it is for people.

Summertime d​og deaths are often associated with hot cars, but even playing outside or being in a space without air conditioning can cause problems. Here's what to know about dogs and heatstroke:

It doesn't have to be super hot to be dangerous.

"It's important to remember that it's not just the ambient temperature, but also the humidity that can affect your pet," Humane Society veterinarian Barry Kellogg says. "Animals pant to evaporate moisture from their lungs, which takes heat away from their body. If the humidity is too high, they are unable to cool themselves and their temperature will skyrocket to dangerous levels — very quickly."

D​ogs don't sweat like people do.

Dogs (and cats) have sweat glands in their paw pads, but they don't do much for cooling. A dog who isn't under too much stress from heat will cool off in other ways, like normal panting, laying in a cool spot or drinking cool water.

Some dogs are more susceptible than others.

Short-nosed breeds like French bulldogs are prone to breathing problems that can get worse in hot or humid weather and make it difficult for them to cool down. Long-haired dogs can also get overheated more easily than other types. Puppies and older dogs, as well as those who are overweight or not physically fit, may also be more susceptible.

D​ogs with certain medical conditions, like hypothyroidism or heart disease, are at higher risk of complications due to heat, according to the American Kennel Club.

L​ack of water is often a cause.

D​ogs left outside without water can quickly become dehydrated and overheated. This is especially true if they are confined in a spot without shade.

T​here are many symptoms of heatstroke in dogs.

The AKC says symptoms can include heavy panting, rapid breathing, drooling more than usual, dry mucous membranes, bright red gums and tongue, hot skin and an elevated heart rate. Dogs that are overheated may also become hyperactive or have problems with balance.

Shock can set in.

Signs that a dog is in very serious danger include pale mucous membranes with white or blue gums as well as a very rapid heart rate. A dog might hyperventilate, have muscle tremors, collapse and become comatose.

Dogs with signs of heatstroke may need immediate emergency care.

Consult with your veterinarian on what steps to take. General ways to bring a dogs' temperature down include cool water and using a fan.
