Coyotes and larger predators can harm English shepherds and it is not safe for either dogs or stock to rely on them for this type of guardian role.
Since the English shepherd creates a relationship with their stock they are generally nurturing toward them, including the young. They will tend to those that need it and let the owner know if something is amiss. They are concerned with the health and well-being of their flock and are accepted by the stock. Once they learn their job, this trait allows the English shepherd to be out amongst the stock without working them; they are alert to the presence of predators, including hawks, foxes, and raccoons and will guard the stock against them.
