I. Dogs do sweat, although the heat dissipation is poor, dogs also have 2 types of sweat glands

We all sweat after exercise or when we spend time in the sun as a way to dissipate heat, but in either case, dogs will just pant and seem to have no sweat at all on the surface of their skin and hair. However, dogs do sweat to dissipate heat, but the effect is less pronounced, or the owner doesn't notice.

How do dogs sweat?
Among all mammals, we humans have one of the most efficient heat dissipation rates because we have sweat glands all over our bodies. In dogs, there are two types of sweat glands. But the difference is that dogs' sweat glands play a much lesser role than ours, and their sweat glands can only produce a small amount of sweat to maintain the balance of salt in the body while excreting some of the waste products of the new generation. For dogs, sweat is also a relatively good-smelling body odor.

Sweat Glands in Dogs
The secretion glands are a type of sweat gland in dogs, and whether dogs have been exercising or have been overcome by the heat of summer, the secretion glands in their bodies will start working. The secretory gland is located in the dog's paws and is also found in the footplates of humans, apes, monkeys, and rodents. It produces sweat to help cool the dog or other animals, so in the summer, owners will notice that their dog's paws are always wet and sticky.

However, the secretory glands have more than just a cooling effect for people, when we are nervous we tend to get sweaty hands, this is the secretory glands in action. In addition, although the secretory glands have a relatively small effect on heat dissipation in dogs, according to researchers and veterinarians when the dog's paws sweat and become sticky, it helps to increase the dog's grip, so it is less likely to slip and fall.

Another type of sweat gland in dogs is the parietal secretion gland, which is almost all over the dog's body, but these glands do not produce sweat, only some pheromones. Dogs generally communicate with each other through these pheromones in their scent.

Dogs still mainly rely on panting for heat
As mentioned above, although dogs have sweat glands, they are very inefficient at dissipating heat, and the main way to dissipate heat is by panting. During inhalation, the dog's blood can replenish the rapid loss of oxygen, and this blood will flow to the dog's ears or other skin tissue when the process of blood diastole helps the dog to dissipate heat. At the same time, panting can also make the dog's tongue cooler, the breathing process will have air flowing over the tongue, making it evaporate the water in the mouth and absorb heat.

Even so, the dog's heat dissipation efficiency is still far lower than ours, so sometimes we can still endure the heat, but the dog may have heatstroke, once the dog has heatstroke, serious words may lead to their unconsciousness or even death. In the summer or after exercise, the owner had better take the dog to a shady and cool place to rest and prevent skin sunburn.

Second, the dog's body temperature rises, and the metabolic rate will also speed up, so the owner needs to give it timely hydration or electrolyte-containing drinks. Finally, some owners may take their dogs for a haircut, but the hair can protect the skin from UV damage, so it's best not to cut it all off. Have you guys ever felt your dog's sweat?

II. Causes of dog sweating

Because the dog's whole body is covered with fur, it is difficult to see if the dog is sweating, so will the dog sweat when it is too hot? Dogs do sweat, and sweating is also the cause of body odor in dogs, and dogs do not sweat to regulate body temperature, they dissipate heat mainly through the tongue and paws.

The ancestors of the dog originated in the ancient times of ice and snow, so they are clad in long hair to preserve body warmth. Under the thick coat, it is difficult for the sweat glands to play a role in heat dissipation. Moreover, the coat has blocked most of the heat, and the function of sweat glands is greatly reduced, so dogs never rely on sweat glands to dissipate heat. Even the Mexican hairless dog, living in hot weather, is still dry and sweaty.

Dogs sweat for reasons other than heat dissipation because sweating has no role in regulating body temperature at all. Their exocrine sweat line is mainly at the paws, the reason they sweat in the paws, is mainly to keep the touch surface soft. Otherwise, the dog's paws often rub against the ground will make the dog's paws dry and strong. When the weather is too hot, heat may stimulate the sweat glands of the dog's paws, and secrete more sweat, so it will leave wet footprints on the ground.

The dog's method of heat dissipation is to regulate body temperature through the evaporation of respiratory ducts, so in the summer, the dog will open its mouth wide, stick out its tongue, and pant vigorously, just to moisten its tongue and evaporate its body temperature. In the heat of the day, remember to let the dog drink more water, you can let them cool down the heat.

The dog will therefore sweat, and this is the main reason why dogs have body odor, so even if you help your dog shave, the effect of helping it to dissipate heat is limited, and generally speaking, summer is not too recommended to help your dog shave, as to whether to shave or not or have the owner decide for themselves.

Three: Do dogs and cats sweat or not?

In hot weather or with a lot of exercises, we humans always sweat, but cats and dogs don't sweat even a drop when they are covered in dense fur all year round.

Whether it is a dog or a cat, they will sweat in hot weather or a lot of exercise, but their sweat secretion is very little, and the general public is difficult to find.

First of all, let's talk about our silly human partners - dogs.

The sweat glands of dogs are mainly distributed in the fleshy pads on the soles of the feet, the sweat glands on the soles of the feet can be discharged through sweat to heat for the dog, but the secretion of this sweat is limited, it is difficult to find with the naked eye, we need to touch to feel.

In addition to the feet pad sweating heat, dogs have the following three ways to dissipate heat.

First, the dog's paws have long-term contact with the ground, the paws and the ground can form the role of heat transfer, which takes away a part of the dog's body heat.

Second, the dog through the tongue to a large number of heat dissipation, the movement of the tongue will make saliva, although this looks a little disgusting, the evaporation of saliva can take away a lot of heat from the dog, as the owner, we must not dislike them ah.

Third, in the case of a very hot body, dogs will also show their bellies and other ways to dissipate heat, so when the dog is "honest with you", it is not only expressing trust in you, but also their heat.

Then we talk about the sometimes arrogant and sometimes clingy cats.

Cats, like us humans, have sweat glands all over their bodies, mostly in the exposed parts of their bodies, such as their noses, hips, paws, etc., but only the fleshy pads on the soles of their feet will sweat a lot.

There are three other ways for cats to dissipate heat.

First, the contact between the fleshy pads and the floor also dissipates heat for cats, similar to that of dogs.

Secondly, cats will lick their fur and let their saliva evaporate to remove body heat.

Third, when the body temperature is super high, or even close to the edge of heat stroke, cats will also spit out their tongues to dissipate heat, this cat spitting out their tongues is relatively rare, but once this happens, it proves that the cat's physical condition is in a critical moment, owners must promptly heat for the cat to relieve the heat.

In short, cats and dogs are also sweating, when the weather is hot or after a lot of exercises, owners must not give cats and dogs wearing shoes, with a muzzle, which will seriously affect their heat and sweating, and even lead to their heatstroke phenomenon.
