Because it was contaminated with someone's blood, a cheating system called loyal dog training was triggered. Thus embarking on a bright road to domesticating loyal dogs!

The aggrieved System Lord: [What I gave you is not a dog, but a tall, mighty, domineering and loyal dog!
It's unrealistic, don't take it seriously, just watch the fun!
