Article: Once the foal gets past the shoulders, it should come out quickly and land on the straw. If the sac around the foal is still intact after the foal struggles a bit, you'll need to rip or cut it open so the foal can breathe. Also, tilt the foal's head upward to clear it's nose of fluid.  If tilting doesn't clear the nose, you can use a suction bulb to pull out mucus. If the foal is having trouble breathing use a towel to rub its abdomen and ribs, which may help it start breathing. If it's still having trouble, you can hold the foal upside down for a moment or two to let the fluid drain. Start artificial respiration if the foal doesn't breathe on its own by cupping your hands firmly over its mouth and nose. Breathe into one nostril steadily and gently, letting its chest rise and fall, then push air into the nostril again. Keep going until it can breathe on its own. Do not try to cut the cord. It will break naturally on its own. Have an umbilical clamp on hand. The mare will likely lay down on its side for 20 minutes or so while it recovers. During that time, the mare will likely display colic-like behavior as she works to deliver the placenta. Tie a knot in the placenta with twine and let it hang so your horse is more likely to pass it safely.   Never pull on the placenta since it could break inside the mare and make it sick. The foal should stand up within an hour and start nursing within 2. If it doesn't, call your vet. The navel stump is what's left behind on the foal when the umbilical cord breaks off, and it will be on the foal's belly, much like a human belly button. Pour an antiseptic solution into a cup. You can use a 0.5% chlorhexidine solution or a 2% iodine in it. Gently push the navel stump into the cup and hold it in there for 30 seconds. This is stage 3 of labor, and the horse should pass it within 3 hours, though often it will happen within 1 hour. It will look like a large, white bag. If you don't see it within 3 hours, call your veterinarian, as not passing the placenta is dangerous for the mare and is considered an emergency.  Once the placenta passes, spread it out so you can see the whole thing. If it has any pieces missing, call your veterinarian, as pieces that stay inside the horse can cause infection.  Never try to remove the afterbirth from the mare, as this could lead to a serious uterine infection. Save the placenta so your vet can look at it to learn about the health of your mare and foal. If the mare doesn't want to eat, seems depressed or colicky, or seems weak in the days following labor, call the vet. Similarly, if she has discharge from her vulva that's brown or smells particularly bad or if you see a lot of blood with it, call your vet. If the foal seems to be having trouble nursing or getting around, call your vet.

What is a summary?
Get the foal breathing as soon as it is fully delivered. Give the mare and foal a chance to rest while you wait for the placenta. Clean the navel stump by dipping it in an antiseptic. Watch for the passing of the placenta. Call the veterinarian if the mare or foal show signs of trouble in the next few days.
