Most people are well aware of seeing eye dogs, a dog that guides a blind person. A few people are aware of some seeing eye horses, these being horses that are trained to act as guides for a blind person.
You probably are not aware of seeing eye sheep and goats that act as guides for a blind horse. Apparently a quarter horse mare, named Sissy, has 10 companions who act as seeing eye animals. These consist of sheep and goats who act as guide animals for the 15 year old grey mare (horses can live into their early 20's, but are often sent to slaughter or euthanized in their teens).
The goats and sheep stand between Sissy and the fence to stop her from walking into it, they herd her (presumably with their vocalizations) towards hay, and water, allowing her to feed equally. They even direct her to shelter when it is needed. This all makes perfect sense when one understands that horses, goats, and sheep, are all herd animals. Having a large horse actually helps the smaller animals in coyotes are less likely to attack small animals when a larger (particularly taller) animal is with them.

Sissy and her farmyard pals are currently living in Deer Haven Ranch, a 300 acre rescue and retirement home for unwanted animals located in Montana.
