how do a horse's features help horses survive
1 If your horse is soaked to the skin, shivering or his ears are cold, heâs chilled and stressed; he needs a dry shelter and perhaps a blanket.  Long winter coats can hide early signs of weight loss, skin problems or lice, so check your horse daily, including his skin, eyes, feet and overall well-being.
The horses graze together and rest together. Their sharp hooves are used to dig holes in the ground, if needed, to find water. The Przewalski's horses at the San Diego Zoo Safari Park graze in their field exhibit but are also fed alfalfa, hay, and carrots.
