I really dont have much input, but the more i read, the more it seems that it could very well be possible to fix this.. but not until you can get that hubs of yours to cool his roll!!! I really think he's adding hugely (though i dont blame him one bit as it's a horribly fearful thing to watch this with your beloved dogs) Being Pack leader is one thing, but i sort of see he's really causing them to change their 'play' attitude, into oh crap, dads upset mabie i need to take care of something quick... I had a short lesson (from all these here) myself as i was a mushpot to my boy and nothing but do do do for him. He needed me to be LEADER, but i didnt understand until he got agressive 2x.. And both times, it was because i freeked out and he didnt know what to do but react.. Had to change some of that up, keep my cool with it all, and all is well now, and he is a happier boy knowing im going in the lead. Anyway, I wish you all the luck in the world. Looking forward to hearing what the trainer helps you guys with. Sadly, i admit, it was ME that needed to change. Issues can happen to us all, but we can exacerbate the issue if we dont know how to follow up from there .. hope i made ANY sense
