Coyotes are most likely to threaten foals and injured or less mobile horses. Coyotes are less likely to attack a healthy, full grown horse except out of desperate hunger, which then requires the help of a pack.

How big of an animal will a coyote attack?

Coyotes will attack and kill pets, especially cats and small dogs (less than 25 pounds). The best way to protect pets is to not allow them to run free. Cats should be kept indoors, particularly at night, and small dogs should be on a leash and under close supervision at all times.

How do I protect my horse from coyotes?

Make sure the perimeter fence around your land is in good shape and doesn't have any gaps in it. Determined predators will get past this, however, so at night your horses should be kept in either a secure barn or stables with tubular steel bars and chicken wire to keep out predators of all sizes.
