An aquaintance of mine took care of her elderly father. He had a Schipperke as a service dog. The father had been a farmer, and although they leased most of the farm at that point, he still liked to drive a small tractor out to mow one of the pastures. He had a diabetic incident and fell off the tractor. The dog came in from the fields and barked until they went out to him.
The dog also pulled the covers off him every morning to make him get up and barked if he didn’t fix breakfast and eat.
My little black pug used to suspiciously sniff my right side, and seem bemused, and would sniff again, like they do when you’ve run into another dog when you’re out. I thought it was cute. Turned out it was cancer. And pugs don’t have much to sneeze with in the nose department! But my little boy stuck like glue to me all through the cutting and pasting me back together.
