Sweating in dogs.

Dogs pant as a means of evaporative cooling: when a dog gets hot, it will open its mouth and breathe heavily. As water evaporates from the dog's tongue, nasal passages and lungs, this helps lower its body temperature.While dogs primarily use panting to cool themselves down, they also sweat,dogs actually sweat through their paws. Catherine Carrier, a veterinarian and Animal Operations Senior Manager at Covance Laboratories, a contract research facility that partners with pharmaceutical companies carried out a research, this was the first to describe hyperhidrosis, or excessive sweating, in beagles. She explained that while working with beagles she noticed something peculiar in several of the dogs. The paw pads which are a specialized type of skin that's heavily keratinized and its tough for walking on. In these dogs the paws were damp and in some cases, they were even dripping with sweat. This leads to a great deal of pain because the skin is softer and more delicate than a normal paw pad more like having an open blister. The sweat glands in the dogs' feet may also serve another purpose, panting cools a much greater surface area than a dog's paws would. The sweat on a dog's paw pads actually has more to do with traction than temperature. In other words, it makes their paws tackier and better at gripping the ground. According to Dr Catherine , a normal dog foot should smell like they just had their paws in a bag of corn chips, because they do sweat through their feet, and it has a salty smell.Dogs also have sweat glands in their noses, but again, they're not necessarily for cooling purposes. contributed by Live Science.
