using this logic path is extremely manipulative in my opinion. Its not kind to dog owners to make this comparison and unkindly profit off of the unknowing public. Any expert in behavior immediatly knows how unfounded this claim is. A zoo animal is so understimulated living in confirmment and the level of deprevation an animal is under leads them to either sterotypie behavior or the choice to might as well entertain the zoo keepers. Many times when these animals opt out there is no other choice and the zoo kepers cant do anything except try anther day or another week. Thats fine if you want to train your dog how you wish, but do not conflate zoo training to dog training.
