Duggie, an experienced border collie and Zach’s best friend and business partner, loves nothing more than working with the sheep. If he’s not herding, he’s staring intently at Zach or the sheep, waiting for a whistle. Duggie’s chores include gathering the sheep, guiding them on and off the trailer, and guiding the sheep to their enclosure. His other interests include frisbees, tummy rubs, and shedding in the truck.
