I had a pit circle me near the front of my house several years ago. Took me over 10 minutes to maneuver toward my door and get in. All the time this was going on I was pelting the critter in the head & torso with rocks. The rocks hardly moved him. It annoyed him at best....good enough to distract him & get me out of his clutches I suppose.
I am very glad you made it to the house. How big were the rocks? Have you had any experience in the wild?
