ISO Small Male herding dog

I have a a mini aussie x corgi, 20-25 pounds that I am looking to breed. Im looking for a male that is around her size, preferably with at least one or a mix of these breeds:

- mini aussie

- smaller border collie

- mini heeler

- corgi

Not looking to breed to a full corgi or Merles!

Preferably a farm or ranch dog, good temperament, short hair, good around livestock and kids.
