@Ocean your continued insistence that humans bring no value to the planet (go ahead and backtrack that again) has really cost you all credibility. That, along with telling people, who have more years in the fields they dispute you on than you have on this planet, they are dead wrong.
You’re not going to change anyone’s mind because you “know someone who does this who said that”. Saying a GSD does not have a high prey drive makes me recall a couple of my professors favorite quotes; “a little learning is a dangerous thing, drink deep or taste not of the pierian spring” and “it’s better to remain silent and be thought a fool than to open one’s mouth and remove all doubt”.
Any herding breed worth working has a high prey drive. It’s what makes them good at their jobs. GSD’s do have a high rate of fear aggression. Fear aggression leads to UNPROVOKED ATTACKS. Provoked carries a connotation of willingness or intent.
A child riding a bicycle down a side walk beeping her little bike horn, GSD suddenly decides bicycle is scary so I will attack the thing that is peddling it....... yeah, not likely. The more plausible explanation is GSD with high prey drive sees something running and making a high pitched sound like a wounded animal so I’m going to run it down and catch it. It is worth noting that in either scenario, the child is not at fault. The child did not do anything to provoke the dog and may not have ever seen the dog. Rest assured that if the zombie apocalypse descended and our society was taken back centuries all our cuddly poodles turning feral would be one of the greatest daily dangers to humans along with all the disease brought in by those cute little mice.
Humans are the ONLY species that attempts to give all creatures a space. The big cats will kill their own parents to take over a prime location and would hunt every other predator to extinction if they were capable. We do treat illness in these animals that would otherwise lead to painful anguishing deaths. We do try to compensate for the damage our own progress causes. But again, natural selection has favored man rather than the tyranasaur. Blame Mother Nature for a bad plan, not a species for succeeding.
Take your parrot back to it’s species place of origin and release it. Never own another pet because they have all been removed from their natural environment at one time. I hope you’re vegan and eat no plant that isn’t native to your area and grown by your own hand. Because until you do that, the only thing you are being successful at is the pot calling the kettle black.
