We started with an Australian Shepherd, i thought he needed a mate, little over 2 years later we had puppies everywhere...we ended up keeping 2 more....turns out they kept our cattle herded, as well as our grandkids, and our cars as we would come into the driveway....now 16 years later, 3 have crossed the rainbow bridge and only 1 left...he still tries to keep me and the husband as well as the 2 jack russells herded.
