The sweat glands in dogs that regulate body temperature are distributed all over the dog's body, but they do not sweat. Only the sweat glands on the foot pads sweat, so it is mistakenly believed that dogs do not have sweat glands. When the weather is hot, the dog's foot pads will also sweat and feel moist to the touch. Therefore, if there is a lot of hair on the foot pads, trim it appropriately to avoid affecting the dog's heat dissipation.
