I have a friend that lives in Cave Creek, Arizona and she helps find good homes for animals that are rescued from people in the area whose animals get confiscated for neglect. She also trains Mustangs and finds good homes for them. I asked her advice. What is the best way to get Zum into the two-horse trailer? She suggested that I put alfalfa inside the trailer as temptation for Zum. I tried this and guess what? It worked like a charm! Now Zum loads and unloads into the two-horse trailer easily. I always bring an extra bucket of alfalfa so I can load him when Huszar, Zum and I come back from a trail ride!
