Summer is my favorite time of the year but many summertime activities can be dangerous to your pet’s health. By far the most common threat is the risk of overheating. At Friendship Hospital we see so many cases of heatstroke every summer. I feel it is necessary to constantly warn dog owners about the dangers of hot weather.
Dogs are much more susceptible to heatstroke than their human companions are. As if wearing thick fur coats weren’t enough of a challenge, dogs have only two ways of dissipating heat: by panting, and through their paw pads. When the temperature rises, neither of these cool-down tricks works very well. Panting becomes much less effective when the weather is hot and humid, and, when your dog walks on a scorching sidewalk his paws stay too hot to help him cool down.
All dogs can be affected but the “Smushy-faced” (“brachycephalic” is the technical term!) dogs like bulldogs and pugs are especially susceptible to heat-related illness. This is because breed characteristics such as narrow nostrils and elongated soft palates decrease their ability to effectively cool themselves. Please keep this in mind if you have a brachycephalic breed at home.
If you’re out on a walk with your dog and he suddenly lies down, collapses r becomes unresponsive, seek veterinary care immediately. DO NOT try to cool down your dog on your own. Instead, get to a vet as quickly as possible.
If for some reason you can’t make it to a veterinary hospital immediately there are a few cooling measures you can begin. Fist take your dog’s temperature rectally with a digital thermometer, normal is 100-102. You can then soak a towel in tepid (not cold) water, place it over your dog, and aim a fan at him. Continue to closely monitor his temperature and once it hits 103 degrees discontinue cooling. Even if your dog seems fine you should take him to a veterinarian as soon as he is more stable.
What makes heat stroke potentially fatal is that the patient can develop a condition called disseminated intravascular coagulation or DIC that causes massive and widespread damage to the blood vessels. This quickly results in multiple organ failure and the patient loses the ability to clot his blood. Treatment consists of aggressive supportive care and plasma transfusions, both of which are very expensive and not guaranteed to prevent death.
When it comes to heatstroke, the best treatment is prevention. Here are some commonsense tips to help keep your dog cool and comfortable:
- Avoid taking your dog out during the hottest times of the day. (Quick rule of thumb: If it is too hot for you, then it is definitely too hot for your dog!)
- Keep an eye out for unusual behavior: If you are out in the hot weather with your dog and he slows down, lies down or acts reluctant to keep walking, you should let him rest, offer him cool water and head inside immediately.
- Make sure your dog has cool, fresh water available at all times.
- NEVER leave a dog (or any other pet) in a parked car when it is even slightly warm out. The temperature in the car can rise very quickly and before you know it you have an overheated animal.
- Don’t take your dog running. I am not a fan of running with your dog but in warm weather it is an especially bad idea.
I hope these tips help you and your dog enjoy the beautiful and toasty summer weather!
