Make sure you and your horse drink enough water in the winter. Your horse may be put off by ice in his trough or the cold taste. Encourage him to drink by making sure he has plenty of fresh water available and consider adding sugar or using electrolytes. Drink plenty of water yourself too, even though it’s cold. It can be in the form of hot drinks like tea! You both need it to make sure your immune system works properly. Water carries oxygen to cells and so helps you to get rid of toxins.
