How Dogs Keep Cool

What do dogs do to keep cool?

Unlike humans, dogs can’t sweat through their skin. They rely on panting and releasing heat through their paw pads and nose to regulate their body temperature. If they can’t cool down, they will quickly develop heatstroke, which can be fatal to dogs.

How do they do it?

Dogs can cool themselves down through panting by evaporating water in their mouths and across the dog's tongue, which cools them off. Panting also helps dogs regulate body temperature because it causes air to flow over the dog's wet mucous membranes in its mouth and nose.

As for the releasing heat part, more than 70% of a dog's body heat is dissipated through its body surface or skin. As a dog's body temperature increases, the blood vessels in their skin expand to increase blood flow. That allows heat to be released from the blood. The body expels the heat from its body into the environment.

Why don't these methods work on other animals?

There are a couple of reasons why, all of them important:

First, since dogs don't have working sweat glands like humans do, they can't sweat to cool down, so panting is their solution to regulating body temperature. Many other mammals do have working sweat glands and don't rely on panting as much.

Also, the structure of the dog respiratory system makes dogs more likely to pant. Their narrow throats and long, soft palates make it easier for air to flow quickly in and out during panting. Other animals don’t have a respiratory system that’ll allow that level of panting.

Third, dogs have a higher body temperature (101-102.5°F) than most mammals. Their warmer temperature means they need to cool down more often - through panting. Animals with lower average body temperatures don't need to pant as often.

Lastly, dogs, and also wolves, have a higher metabolic rate than many animals, which makes more internal heat that needs to be dissipated. Again, this grows their need for panting compared to other, less active species.

In conclusion, panting and releasing heat are the main ways dogs cool down. The ways dogs do it is both complex and fascinating, and there are many different, important reasons it doesn’t work on other animals. Overall, the way dogs cool down is amazing to learn and to teach for me, and I hope you learned a lot from my essay.

Thank you!
