It doesn't matter if pitbulls are loyal and become attached to a single person. This is a common attribute among many dogs of many breeds and mixes, and is beside the point anyway. As a longtime dog breeder and owner, I've said before, as an example, that an Irish Setter whose ancestry hasn't hunted for a hundred generations will still go on point if it happens upon the scent of a quail. But pointing at a quail does not result in kids and adults being ripped to pieces, which will happen again with this pitbull if it is not euthanized.
