BEAT THE HEAT

Running when it's hot isn't just hard--it can be dangerous. To get you prepared here's everything new under the sun.

Hot Dogs

If you think you've got problems running in the heat, try wearing a fur coat. Your dog does this every day. Here's how you can help.

Easy, Lassie!
Let your pooch get used to the heat before starting on long, sun-drenched runs.

Big Dogs
Short-legged and hefty dogs don't run as well as other breeds, and heat makes it even tougher. The same is true of most canines younger than 18 months or older than 10 years. Walk them instead.

Dog Tired
Stop to rest if Scout is lagging behind or panting heavily.

Bone Dry
Panting is a dog's main cooling mechanism, because he only sweats through his tongue and paw pads, which is inefficient. Share your water before, during, and after running, and wait for him at all water stops.

Heavy Breathing
Frothing, reddened gums, and excessive panting are symptoms of canine dehydration and heat illness. If rest and drinking don't help, get your dog to an emergency animal clinic.

Hot Pads
Paw pads can burn on asphalt, so stay off the roads.

How Heat Can Hurt

Illness Cause Symptoms Treatment Prevention
Heat Cramps Dehydration leads to an electrolyte imbalance Severe abdominal or large-muscle cramps Restore salt balance with foods or drinks that contain sodium Don't run hard in the heat until acclimatized, and stay well hydrated with sports drink
Heat Fainting Often brought on by a sudden stop that interrupts blood flow from the legs to the brain Fainting After the fall, elevate legs and pelvis to help restore blood flow to the brain Cool down gradually after a workout with at least five minutes of easy jogging and walking
Heat Exhaustion Dehydration leads to an electrolyte imbalance Core body temperature of 102 to 104, headache, fatigue, profuse sweating, nausea, clammy skin Rest and apply a cold pack on head/neck; also restore salt balance with foods and drinks with sodium Don't run hard in the heat until acclimatized, and stay well hydrated with sports drink
Hyponatremia Excessive water intake dilutes blood-sodium levels; usually occurs after running for four or more hours Headache, disorientation, muscle twitching Emergency medical treatment is necessary; hydration in any form can be fatal When running, don't drink more than about 32 ounces per hour; choose sports drink over water
Heat Stroke Extreme exertion and dehydration impair your body's ability to maintain an optimal temperature Core body temp of 104 or above, headache, nausea, vomiting, rapid pulse, disorientation Emergency medical treatment is necessary for immediate ice-water immersion and IV-fluids Don't run hard in the heat until acclimatized, and stay well hydrated with sports drink
