Yes, in this book I have read that a hippo has pink sweat, but scientifically saying it I do not now.P.S. I read it in a Japanese book.
No. Even blood, which is the most potent carrier isn't harmful unless you've got a cut or otherwise get it into your system.
yes horses sweat. They sweat when they need to cool down just like humans. The sweat comes out of their pores.
When you sweat your body is just releasing heat and water. Even though you dont feel any cooler on the outside your body on the inside will be releived.
