Mastiffs and Heat Stroke

Giant breed dogs, such as the mastiff are very susceptible to heat related illnesses such as heat stroke. Although heat stroke is a condition that is typically seen in the hot summer months, it can occur at any time throughout the year, if the dog is exposed to high extremes to heat. Since dogs, including mastiffs sweat via panting, through their foot pads and their noses, they are unable to provide themselves with skin that is moist, which provides a cooling sensation. Humans sweat all over their bodies, which allows us to cool ourselves off via this mechanism, but a dog's cooling mechanism does not provide for this.

Although panting in mastiffs is normal when they are trying to cool themselves, it can indicate a serious problem. Mastiffs and heat related illnesses such as heat exhaustion or heat stroke go hand in hand because the larger the breed, the more of a challenging it is for them to cool themselves. When the temperature becomes too hot, it is important that the mastiff, or any dog be removed from the environment as quickly as possible. Canine heat stroke can happen when their body temperatures rise to 106 degrees or higher. A hot car can quickly cause heat stroke, even when the windows are slightly open.

Symptoms of heat related illness and heat stroke in the mastiff include heavy panting, exceptionally bright red gums and possibly collapse. In addition, they might exhibit aggressive behavior and appear anxious and their eyes might have a glazed over appearance. Heart rate in the mastiff who has heat stroke will be elevated to in excess of 120 beats per minute and their pulse might feel weak and thready. Heat stroke in the mastiff is a medical emergency and they need to get to a veterinarian as soon as possible. Typically, treatment for heat related illness in the mastiff include re-hydrating the dog with intravenous fluid and administration of medication that ensures that their blood is properly clotting. Other giant dog breeds that are prone to heat stroke include the Saint Bernard, Newfoundland and Great Dane.

When heat stroke is suspected, the dog should not quickly consume copious amounts of water, because this can contribute to a life threatening condition called bloat. This gastrointestinal condition is seen in giant breed dogs and if not recognized and treated promptly can cause loss of life. Dog owners who suspect heat stroke should pour water on the armpits and groin areas of the dog and spray their mouths with cool water. Another remedy that could prove helpful is applying rubbing alcohol to dog's foot pads because alcohol evaporates quickly and allows for the cooling process to begin. People should not rely solely on home remedies when symptoms of heat stroke present themselves because in these situations, the mastiff will require emergency treatment services.
