Hyperthermia

This summer has been in full swing for several months. In fact, North Idahoans have suffered through tremendous temperature spikes; we have felt triple digit numbers on many afternoons. And we have already witnessed a handful of furry patients suffering from heat exhaustion.

Everyone understands the stress of direct sunlight on a dog or cat. And most pet owners are very careful not to over exercise their pet (or themselves) in the middle of a summer day. But we cannot emphasize enough the threat of a closed space, even with ventilation, on a warm day.

Hyperthermia may be life threatening and requires immediate treatment. A dog's normal temperature ranges between 100 to 102 degrees; we consider anything higher than 104.5 degrees a true emergency. Here's a fact that blew my mind: On a relatively cool (70 degree) day, a recent study from Stanford University Medical Center found the temperature within a vehicle may increase by an average of 40 degrees Fahrenheit within one hour, regardless of outside temperature. Bottom line: We can't be too careful with our animal (and human) companions.

There are other conditions that can affect your pet's sensitivity to heat. Bulldogs and other short-faced canines have very different breathing anatomy — their tracheas (wind pipes) and airways are often reduced in diameter and become stressed easily by the heat. Panting alone can cause elevated body temperature. Obesity and diseases may predispose a pet to hyperthermia — prolonged seizures, poisoning and mild fever come to mind; these are not necessarily caused by the external temperature.

Hyperthermia signs

Symptoms include panting, restlessness, salivating and staggering. As hyperthermia progresses, the gums may look purple or blue tinged. Pets are often very distressed. Severe hyperthermia affects nearly every cell in the body. Organs that are too hot (like over 105 degrees) can actually become jello-like and literally melt down. Blood in the urine is a life threatening sign.

What to do

Place your hot dog in a cool area, grab a fan and place it directly on him. Place moist wet towels around the groin, armpits and neck. You may also apply cool water to his earflaps and paws. This will help immediately drop the temperature at least one degree. Time permitting, try to obtain a rectal temperature. Then get your pet to the vet! As stated above, the inner organs are very susceptible to break down in this state, the pet may need more intensive care.

What not to do

Cooling pets too fast can actually shrink the peripheral (outside) blood vessels and insulate the body's core and organs, keeping them hot! So, be sure to stay away from super cold water or ice. Try not to leave pets unattended. Don't force him to drink — or do anything for that matter. Stress will increase body heat!

To summarize (and repeat!): If busy people travelling with “Fluffy” need to pop into a store for a “quickie,” remember this: When in doubt, take Fluffy out of the car!
