The situation that we are currently facing world-wide not only impacts people but also our horses (and other animals) in our care.
Make sure that you have stocked up on extra supplies, medications, forage/feed and other necessities for all your animals. Check with your essential needs providers (i.e., feed stores) to see if they are open and if they have methods of providing you with your needs (i.e., ordering online or by phone, putting your order outside the door of the store as you arrive or other alternatives).
It is also important that you write out the care instructions for your animals. In the event of illness or injury, you have a plan for caring for your animals so that someone else can step in and help.
