SUMMER PROTECTION OVERVIEW
What you can do to help keep your pets healthy and protected in the summer heat?
Summer, my favorite season, is here. The long days provide me and my dogs with extra time to enjoy all our favorite activities: hiking, camping, long walks, and outdoor adventures. Of course, long summer days also bring the risk of heat exposure to dogs.
The consequences of a dog overheating can be very serious. Heatstroke, or hyperthermia, can occur quickly and the result can be deadly. By understanding how dogs keep cool – and what we can do to help – we can ensure our dogs don’t overheat, so we can all enjoy those dog days of summer to the fullest.
WHEN DOGS GET HOT
You may have experienced those very hot days when every pore in your body oozes sweat. Sweating is a very effective cooling mechanism; the evaporation of the moisture on the surface of your skin cools your body.
But dogs don’t sweat the way we do, and their ability to cool off is much more limited. Dogs cool themselves primarily through the process of panting and breathing. When dogs pant, the air passing over the saliva in their mouths helps them cool. In addition, the lining of a dog’s lungs serves as an evaporative surface, much like our skin when we sweat. Blood vessels in the face, ears, and feet can also expand, helping to dispel heat from the body.
A dog’s body temperature is normally between 100.2° and 102.8° Fahrenheit. When a dog’s cooling mechanisms are overwhelmed, his body may no longer be able to cool itself adequately, and the dog can become overheated. Dogs who get too hot can suffer from dehydration, heat cramps, or heat stress. If a dog’s body temperature rises past 104°, he’s in serious danger. If the body temperature continues to rise above 106°, heatstroke can occur.
Heatstroke is a life-threatening condition that can cause lethargy, weakness, collapse, seizure, coma, brain damage, and even death. If the body temperature reaches 109°, his heart, brain, liver, and kidneys can shut down.
Fortunately, heatstroke can be prevented. And if caught early, in its initial stages, it is reversible. An overheated dog is, quite obviously, a medical emergency. Even if you are able to cool the dog down, you should seek medical treatment if you suspect your dog has suffered from heatstroke. Problems associated with heatstroke – including kidney failure, respiratory arrest, abnormal heart rhythms, and seizures – do not always show up right away. Immediate veterinary treatment can help minimize the risks and save the dog’s life.
HEAT STRESS IN DOGS
Dog’s can suffer from heat stress in just a few short minutes, even when the temperature doesn’t seem that hot to us. How will you know if a dog is at risk for overheating? There is not an exact answer to this question; it depends on the dog and the situation.
All dogs are at risk in extreme temperatures. But a dog who is accustomed to 90° weather may have less risk on a very hot day than a coastal pup vacationing in the Arizona desert. And, the air temperature is only one consideration: humidity, sun exposure (or lack of shade), amount of time in the heat, level of exertion, and availability of water can all affect how well a dog tolerates heat.
Certain types of dogs, including northern breeds like Malamutes or short-muzzled (brachycephalic) dogs like Pugs and Boxers, can have a more difficult time in the heat. Puppies under six months, older dogs, and overweight dogs can also have a much harder time when temperatures rise. Dogs on certain medications or with medical conditions like heart or lung disease will be more susceptible to heat exposure. A dog who has suffered from heat stress or heatstroke in the past is more likely to have problems again.
Plus, we’ve all met dogs who are driven to play or work no matter how tired or hot they get; think of a Border Collie at a Flyball match. Along with the outside temperature and humidity and the health of the dog, you have to take into consideration the dog’s personality and ability to stop himself from playing if he gets uncomfortable.
The best way to know if your dog is at risk for heat illness would be to monitor your dog’s body temperature; of course, this is not very practical in everyday life! You can also become familiar with how your dog responds to heat and the signals he gives that indicate he is getting hot. Panting more than usual, declining to engage in a favorite activity, moving slower than usual, searching for shade, or digging for a cool spot can all mean a dog is hot. If your dog is exhibiting any of these signs, it may mean he is already too hot and you should take immediate steps to help him cool off.
BIGGEST RISKS FOR HEAT STROKE
Leaving a dog in the car is one of the most common causes of heatstroke. On a relatively mild 70-degree day, for example, a closed car can heat up to 120° in a matter of minutes. Because dogs can’t cool off effectively while sitting in an oven-like car, they can quickly overheat. Cracking the windows or parking in the shade may not significantly reduce the car’s temperature.
Dogs can suffer heat exposure at home, too. On a warm day, a concrete dog run can heat up quickly. A backyard that lacks shade, or with fencing that blocks cooling breezes, may make the dog’s environment many degrees hotter than where you relax, comfortable, in the house. Neighborhood walks on warm days can also pose a risk. Hot asphalt and concrete can reflect heat, both creating an uncomfortable walking surface and increasing the risk of overheating.
Vacation time can pose extra risks for dogs. Vacations often lead us to different environments and climates – and often into the heat. Hanging out at a campsite, hiking on a warm day, even riding in a boat can put a dog at risk for heat-related illness. Beaches, especially if the dog is not inclined to cool off in the water, are also a risk. A dog traveling in the back of a car may get too much sun exposure through the window.
KEEP YOUR DOG HYDRATED
Heat is definitely not a dog’s best friend, since dogs lack the ability to cool themselves well in extreme weather conditions.
With the rise in dog sports, more us are asking our dogs to run, jump, and participate in other activities on hot summer days. Dogs, especially those who are keen for games or who desperately want to please us, may continue to play no matter how hot the day, or how overheated they are becoming.
Along with heat illness, dogs can get sunburned. Just like people, dogs with pale skin and light-colored fur are at greatest risk. Sunburn can increase the chance of heat illness. Regular sun exposure over the long term can cause skin damage and put your dog at risk for skin cancer. Areas commonly affected with sun damage are the ears, nose, and eyelids.
In addition, walking in exposed areas and visiting outdoor flea markets or street fairs add the risk of burning the dog’s paws. Hot paws can become sore or even blistered, and walking on a hot surface may add to the
dog’s susceptibility to heat exposure.
SHADE PROTECTION AND YOUR DOG
A lot of the methods for protecting your dog from heat stress are just common sense:
CLIP THE DOG'S COAT?
Expert recommendations vary on the topic of whether you should clip a dog’s coat to assist with heat management. The ASPCA suggests that for a double-coated dog (like a Chow), trimming the dog’s fur may help. But don’t shave the dog! Leave at least one inch of coat to provide some insulation and protection from sunburn. Generally, long-haired dogs with a single coat (like rough-coated Border Collies) should not be clipped, as their coats may not be dense enough to protect them from the sun when cut short.
FIRST AID FOR HEATSTROKE
Heatstroke, or hyperthermia, is when the body’s temperature rises too high. It can cause the heart, liver, kidney, and brain to shut down. A dog who experiences heatstroke can go into shock and may suffer irreversible organ damage.
In spite of your best efforts, there may be a time when you will have to deal with heatstroke. Know the signs of an overheated dog; first aid and immediate medical treatment are essential and can help save your dog’s life. Signs of heatstroke include:
WHAT TO DO?
WATER FUN AND SAFETY
Want to cool off your dog on a hot summer day? Think a dip in a river, ocean, or lake is the perfect solution? It may be – especially for those water-loving pooches. But wait. Before you encourage your ball-crazed dog to swim to the middle of the river after his favorite orb, beware of the risks:
ENJOY THE DOG DAYS OF SUMMER
None of us (including our dogs) want to give up summer fun or the enjoyment of a warm day. But a little awareness and a heavy dose of caution will help you protect your dog from heat illness.
Remember, when dogs get too hot, you can generally tell. They slow down, their tongues hang out, and they may even search for a spot in the shade. Most dogs, given the opportunity, will take steps to keep themselves cool on a warm day.
Our job is to make sure they have the opportunity to cool off and to be careful that we don’t ask them to work or play hard when the temperature is too warm for their bodies to handle. Make cooling activities part of your fun together! With a little caution, you and your dog can enjoy the “dog days” all summer long.
