As long as the dog feels a little hot, it will open its mouth, stick out its tongue, and take a big breath, which can secrete a lot of saliva instead of sweat. Dogs dissipate heat by evaporating saliva and lower their body temperature. They drool in large quantities and reduce their body temperature by evaporating and absorbing heat through saliva evaporation. When the weather is hot, this method alone cannot cool down smoothly. Therefore, it is difficult for dogs to lower their body temperature. In particular, pugs, horn dogs, poodles and Chihuahua dogs and other small dogs, because the respiratory organs are short, so they are not good at regulating body temperature, especially afraid of heat, should pay more attention.
