I don't work with rescues, but I had a satisfying day with X today, and when we finished the ride, and I was letting him go at the fence, even though he knew my carrots were all eaten, he just stood by me. he wanted ear rubs and all, and when I finished, he turned around and faced his butt at me. Now, I know many will say "never let him do this!". But, I knew his intention was not a threat, but suppication : "scratch my dock, please". He didnt' push in on my , just turn and wait. and I obliged, and then he left. everyone was happy.
