I read an article about Grizzly Adams once (the real historical one, not Dan Haggerty) and it talked about how he would train the bears by tying them up to stout trees and beating them with a stick until they would submit. It also talked about how he had a large variety of tamed wild animals including deer. I found myself wondering, how did he train the deer? Beat them with a stick? That's pretty hardcore. I know it was a different time back then but taking adorable woodland creatures and beating them with clubs as a training method seems brutal by any standard.
