I haven't yet been able to start my mini aussie Rumor in herding lessons (I hope to soon though!) but she already helps me:
I have a baby goat (nigerian dwarf) who can fit through the goat fence to get out, but doesn't always realize he can fit to get back IN lol

So usually twice a day we put him back in when we feed the goats so he doesn't miss his food (he wants back in then!). But he's skittish, and doesn't want us to come up to him, he runs away. So Rumor helps herd him over to me so I can put him away

Yup, I think she's going to be a great herding dog!
She also starts agility classes next month, I know she'll do great at that as well! She'll be 2 years in Oct, but we've only had her a couple months.
