Dogs also can suffer from weather injuries

All too often when day hiking, we think our dogs are impervious to the warm or cold weather. A body covered in hair and the general belief that animals are hardier than humans both lead to this faulty conclusion.

Warm weather
Indeed, as soon as temperatures hit the high 80s, dogs are vulnerable to heat exhaustion and heatstroke on the hiking trail. This is especially the case when humidity is high.

The problem is dogs don’t sweat like humans and instead must cool themselves by panting. Short-faced dogs such as pugs and bulldogs particularly can suffer from heat exhaustion and heatstroke as they don’t pant or breathe very efficiently, and so have trouble cooling themselves down. And contrary to what one might think, athletic dogs also are quite vulnerable, primarily because they don’t realize they’re overdoing it.

Symptoms of heat exhaustion and heat stroke in dogs include dizziness and heavy panting that doesn’t subside. Of the two, heat stroke is more dangerous, as it can result in fainting, a hemorrhage, and even death.

To prevent heat exhaustion and heatstroke, limit hikes with your dog to the cooler morning and evening hours. While on the trail, ensure your dog rests in the shade for a while and that she has cool water to drink. Should heat exhaustion set in, get them into shade where a breeze is flowing, provide them with water to drink, and wet their coat.

Cold weather
Dogs actually are better able than humans to handle cooler temperatures. The cut-off point is when temperatures hit zero or colder.

Frostbite can occur, especially on the extremities of the nose, feet, ears and tails. Floppy and upright ears particularly are vulnerable to frostbite. The good blood flow of athletic dogs, however, generally means they’re less likely to suffer from it.

Another cold weather issues for dogs is paw irritation due to salt and de-icing chemicals.

To prevent frostbite, don’t hike with your dog when temperatures are zero or below. For paw irritation, avoid walking on sidewalks and roads where salt and de-icing chemicals are used. For both ailments, dog boots also ae beneficial.

Avoiding, treating dehydration on a hike

Make sure children drink water when hiking, as they will dehydrate more
quickly than adults. Photo courtesy of Ken Kistler.

When one has overexerted himself in extremely hot or dry weather or after great exposure to the sun, the body can suddenly dehydrate.

Though dangerous in itself, dehydration can lead to additional problems, such as heat exhaustion, heatstroke and hypothermia.

Drink up
Take note: Children will dehydrate more quickly than adults. After all, a glass with a little water in it will evaporate more quickly than a glass with a lot of water. Likewise, children will use up water more quickly than a full-grown person.

Avoid dehydration by drinking plenty of water. Children need to drink about a quart every two hours of walking and more if the weather is hot, dry or cold and if at a high altitude.

Keep the soft drinks and caffeinated beverages at home. They may temporarily quench thirst, but they won’t adequately replace water the body has lost due to physical exertion. Also, let older kids carry their own canteens or use a hydration system. They’re then more likely to sip water as they need it.

First sign
Parent Rosie M., of Durango, Colo., offers this idea for getting children to drink their water:
“Sometimes kids won’t drink warm water. Fill the canteen half way up with water the night before the hike and place it in the freezer. The next morning, fill the canteen with cold water. Several hours will have to pass before the ice melts, ensuring you have cold water the entire hike.”

Thirst is the first sign of dehydration. The less clear (or more yellow) the urine is, the more dehydrated the body is. Other symptoms include nausea, headache, dizziness, muscle cramps and fatigue.

To treat dehydration, place the victim in the shade. Use sports drinks or packages of electrolyte additives for kids, children, not plain water. Don’t use salt tablets, as they’re difficult to digest.
