To those of you that find this offensive I can only say that what this dog is doing is no different than letting your cat kill a rat or mouse that got in your house. They too would be considered invasive species in your environment. You aren't being sadistic or cruel letting your cat exercise its primal instincts and solving your immediate and possible future issue of invasive control in your environment any more than your cat is being cruel or sadistic while helping you. With that said this was some time ago. He is much better at dispatching these veracious, invasive, harmful predators to our environment. Living in an aquatic environment is a highly predatory existence. If you are not eaten when you are young and weak you will be eaten when you are old and weak. I don't think that this fish has the mental capacity to differentiate becoming a meal for an alligator ,bird , snapping turtle or in this case a dog. In their world being eaten is usually how their life will end.
