Summer heat and dogs: what owners should know
Summer can be a time of joy for pets, but extreme heat can distort a dog’s comfort and health. The body of a dog responds to sudden temperature changes differently from humans, and without efficient cooling, heat stress can occur quickly.
Dogs lack sweat glands over most of their bodies. They primarily dissipate heat through the pads of their paws and, to a lesser extent, the belly. On very hot days, these cooling mechanisms may not be enough, and heatstroke becomes a real risk that needs prompt action to prevent serious injury or death.
How heat affects dogs and what protects them
Just like people, dogs can suffer more severely if heat exposure is prolonged. Older dogs, very young puppies, and those with respiratory or heart issues are especially vulnerable. Breeds with pushed-in faces such as English Bulldog, French Bulldog, Pug, and Boxer are at higher risk because their breathing can be less efficient in heat. Dark-coated dogs also absorb more heat, making them more prone to overheating.
Heat warnings in hot regions
During heatwaves, dogs need extra care. When temperatures soar, the risk of overheating rises quickly. The aim is to keep dogs comfortable and hydrated, and to recognize warning signs early for timely treatment.
heat stroke symptoms
How can one tell if a pet is suffering from heat stress? The following signs may appear in dogs:
-
Body temperature well above normal, often exceeding 42ºC; typical healthy ranges are near 38ºC to 39ºC.
-
Rapid, labored breathing and a sense of fatigue or weakness.
-
A blue tint to the gums or tongue due to reduced oxygen in the blood.
-
Muscle tremors and marked loss of strength.
-
Small red spots on the skin may appear in some cases.
These may be mild at first, but without prompt care, a dog can move into shock, collapse, or fatal outcomes. Early intervention matters greatly for survival.
Tips for cooling the home without air conditioning
When cooling isn’t immediately available, these steps help reduce a dog’s core temperature safely:
How to deal with heatstroke
If a dog shows signs of heat stroke, seek veterinary help right away. If that isn’t possible, the following measures can help in the initial moments:
-
Begin cooling immediately to bring the body temperature down toward a safer range, aiming for under 42ºC.
-
Move the dog to a cooler area, preferably shaded, and away from direct heat sources.
-
Provide clean water for drinking and offer small amounts regularly; do not force large amounts at once.
-
Use cool, damp towels on the head, neck, and chest to help lower the temperature gradually.
-
Ventilation is important; avoid icy exposure which can cause vasoconstriction and slow cooling.
-
Massage the legs to stimulate circulation while monitoring the dog’s condition.
Even if the dog seems to improve, a professional assessment is essential because internal organs could be affected later on. Persistent heat distress should never be ignored.
How to make a homemade air conditioner
There are simple ways to create a cooler environment without cooling systems. A fan aimed at the dog, shaded resting spots, and breathable bedding can all help reduce heat stress. Keeping a routine that avoids the hottest parts of the day and ensuring access to fresh water at all times are practical steps for overall comfort.

Tips to avoid heatstroke
-
Never leave a dog alone in a car or in an enclosed space, even with the windows cracked. Stress from isolation can intensify overheating.
-
Avoid outdoor activity during peak heat hours. Walking on hot pavement can burn paw pads.
-
Offer meals after the hottest part of the day and ensure fresh water is always available.
