Dogs only sweat through their paws! That is why they need to pant if they are hot to release some of that heat. The reason they only sweat through their paws is because most of their body is covered in fur. That means that the sweat would not be able to evaporate and the fur would absorb the sweat back. That wouldn’t cool off the dog! That is why dogs have their sweat glands on their paws so that they can cool off easily!!
