Sandra, that was a sweet story. Your dog knew by instinct that the sheep must be put back where it belonged. That reminded me of my sister's previous dog. She was an Australian Shepherd/Wolf mix. Her friend had a ranch in a rural area and came across the litter one day. This one pup got separated a few weeks later. My sister took it in.
The dog herded people all the time. Like Sandra's dog sheep herding after many years, my sister's dog herded us. We often went hiking together. I can still remember the dog tapping me on the back of the legs if I got out of line. I remember her doing this with my Lab as well.
Julie, I think dogs communicate in ways we don't understand. I think your two dogs showed that.
Haopee, I hope whatever situation you have right now remedies itself soon.
