Gus has taken to harassing poor Fate while she tries to focus on the sheep (she already has enough trouble with the sheep) and Gus rushes up to her, and either climbs on top of her head or puts his paw on her head and barks. Fate is surprisingly good-nature about this, although she snarls at him every now and then.
Gus is definitely trying to break into the sheep herding lifestyle. We’ll see.
