God cared for the lives of the innocent animals. Animals can become as family members to their owners. You should help stray and injured animals even if they are the possession of your enemies. Man is responsible for the actions of his animals. Dog's eat of the crumbs under their master's table.
Man is to have dominion over all the animal kingdom.
Any animal can be trained. God takes thought even for the seemingly insignificant sparrow. God took care in the law to make sure that man would respect nature. God wanted Adam to name the animals. Be subject to the laws which govern animal control.
