Do dogs sweat?

Yes, they do. Dogs have 2 types of sweat glands. The first type is called merocrine glands. These are located in the foot pads of dogs (and cats) and function to help cool the animal. The second type is called apocrine glands. These are located on most of the rest of the dog (and cat) but they do not function to cool the animal. Their purpose is to release pheromones.

no they dont at all all they do is pant

Maybe dogs only sweat through their pads, but my dog's temples get damp when he's hot. I believe that he's part Dalmation and part South Central Terrier.

I haven't seen beads of sweat on his head, but then i haven't seen sweat coming from his paws either.

Yes they sweat. They sweat through their paw pads, and they pant to lower their body temperature.

1) "Perspiration (also called sweating or sometimes transpiration) is the production and evaporation of a fluid, consisting primarily of water as well as a smaller amount of sodium chloride (the main constituent of "table salt"), that is excreted by the sweat glands in the skin of mammals. Sweat also contains the chemicals or odorants 2-methylphenol (o-cresol) and 4-methylphenol (p-cresol).

In humans, sweating is primarily a means of thermoregulation, although it has been proposed that components of male sweat can act as pheromonal cues. Evaporation of sweat from the skin surface has a cooling effect due to the latent heat of evaporation of water. Hence, in hot weather, or when the individual's muscles heat up due to exertion, more sweat is produced. Sweating is increased by nervousness and nausea and decreased by cold. Animals with few sweat glands, such as dogs, accomplish similar temperature regulation results by panting, which evaporates water from the moist lining of the oral cavity and pharynx."

2) "Unlike wolves, but like coyotes, domestic dogs have sweat glands on their paw pads."

3) "There are two kinds of sweat glands: apocrine (or epitrichial) glands and
eccrine (or atrichial )glands. Dogs have both. When it is said that dogs
sweat mainly from their foot pads, this refers to the eccrine glands. Since
dogs do not sweat as a method of regulating their body temperature, the
amount of fluid that a dog loses by sweating is small.

"Each day a dog loses water through its urine, feces, saliva, breath, and
sweat. Unlike humans and horses, dogs do not lose much water due to
sweating."

""Dogs do not produce sweat for thermoregulation. However, they do have
sweat glands, called apocrine glands, associated with every hair follicle
on their body. The exact function of these is not known, but it is
suspected that these are meant to produce pheromones or chemical signals
for communication with other dogs. These sweat secretions probably produce
an individual odor signal that is recognizable by other dogs.

Dogs also have sweat glands on the pads of their paws and on their noses.
These are eccrine glands. When these glands are active, they leave the nose
and pawpads slightly moist and help these specialized skin features
maintain their functional properties. The odor associated with dog paw pads
is much more noticeable on dogs with moist paw pads than on those with dry
pads.

Dogs also have numerous apocrine glands in their external ear canals. In
this location they are referred to as ceruminous glands."

call a vet/aspca

no, they do not have sweat glands..that's why their mouths are aways open..that's how they regulate their temperature taking in air.
