I have no doubt that a GSD or rottie would have the same jaw strength as Jackson, I've just never seen it in action. I thought that he didn't let go because he couldn't, not because he's an idiot. He's just obsessive I guess.
I can't tell my sister how to raise her kids, I can only enforce my own rules on them. She does this stuff all the time. Tells him 'once more and it's a time out' then forgets, or tells him to do something and doesn't follow through. It's really annoying.
I guess it's also the frustration of having them here for nearly 4 months now. Before this they lived in Darwin, so we saw them for 4 weeks every year and that was it. I've gone from knowing no kids, never seeing any as I'm the youngest out of everyone we know, to living with two! (or three if you count BIL lol).
Thanks for listening
