I've seen videos about animal chiropracters that was fascinating. One chiro was treating a giraffe. He stood on a second floor balcony type place and he took the giraffe's head and massaged it to get it loosened up and then cracked his head and upper neck.

They also showed a police horse. The Chiro looked at him and could tell where he was hurting. He massaged and cracked the horses neck and somewhere further back. Then when he watched the horse walk, he could see he was better.

The animals were very cooperative. The giraffe seemed to really like the Chiro.
