4th on 21 interesting Facts About Dogs: Dogs and cats only sweat from their footpads and nose.
A dog’s skin is quite different, which is why you have never seen a dog with sweaty underarms. Most of the dog’s sweat glands are located around its foot pads. That is why, when a dog is overheated, you will sometimes see a trail of wet footprints that he has left behind as he walked across the floor.
I really glad to know about these facts. Thanks a lot.
