The Danger of Summer's Heat

In the season of longer days, we all enjoy activities with our dogs: picnicking, fetching, swimming, hiking. But warm temperatures, especially with an increased humidity, put dogs and cats at risk for heat stroke; a life threatening elevation in body temperature. When the body core temperature rises above 105 degrees Fahrenheit, the pet is possibly suffering heat related disease. Temperatures over 107 cause damage at the cellular level. Depending on the temperature and duration of the high temperature, this damage may be irreversible.

Risks for heat stroke include the following:

Breeds (brachycephalic such as bulldogs and pugs)
Current illness (with fever or mild dehydration)
Chronic conditions (especially heart or lung disease)
Kittens and pups under 6 months old
Geriatric pets
Overweight animals
Animals who engage in heavy exercise

Symptoms of heat stroke include gums that appear muddy pink (instead of the normal reddish pink), excessive panting, anxiety, lethargy. These symptoms often begin after exercise or confinement in hot places. If you suspect a problem with your pet, take a temperature with a rectal thermometer. A temperature of 105 or higher should prompt immediate treatment.

You can initiate treatment at home by submersing the pet in cool water. If submersion is not possible, use a hose. It is important to use cool, not ice cold water, and be sure to get the skin soaking wet in heavy coated animals.

Heat stroke is a life threatening condition that requires medical attention. Please call immediately, a pet with a temperature over 105 degrees needs to be seen on an emergency basis.

Some measures can be taken to prevent heat stroke. Practice these tips when the heat index* is 72 or more for high risk animals and 75 or more for all pets. Many cases of heat stroke occur in spring and fall, when the body is not accustomed to extreme temperatures and owners may be less aware of the heat.

Measures to prevent this condition include:

Exercise early in the morning or late evening (the coolest times of day)
Keep animals indoor when possible or in a well shaded area
Provide fresh water at all times
When necessary, give your pet a cool water bath after exercise

* Heat index ranges form 43 to 103. The index factors in the humidity with temperature because increases in humidity decrease the body's ability to cool down efficiently.
