Dogs Have Sweaty Feet
Humans have sweat glands throughout their bodies, which allows them to sweat pretty much anywhere. But dogs only sweat through the pads of their paws. So, if you ever touch their paws, they’ll feel wet.
Dogs Have Three Eyelids
Unlike humans, dogs have three eyelids. One is the upper lid. The other is the lower lid. Then, there’s the third lid known as nictitating membrane. It’s also known as haw. But whatever you call it, this third lid keeps a dog’s eyes protected and moist.
