One of the first animals that I saw onsite for an animal communication session was a pony. He was 7 years old and was originally from Germany. The pony had become unruly in the riding arena.
This pony had a German name. He did NOT like it and wanted to be called "Henry". The young girl who rode him and the staff at the riding stable agreed to call him Henry. Immediately there was a noticeable improvement in the pony's behavior. Henry and the young girl were partners for four years. After that, she had grown a lot and desired to ride a big horse.
Henry was sold and now has a close relationship with another young girl in New York. And yes, he still loves being called Henry :)
