Hi mate

I only just caught up on this thread, terrible to hear and hope your kids are ok.

Personally I would not keep them as that behaviour is natural for those dogs, along with pitbulls etc and when taking them out they always attack the other dogs, My Jack has been attacked a few times and especially when there are 2 of these as they go into pack mode.

Also just make sure your son isn't scared with all this as they tend to have a fear of dogs for a long time if not life so if he can't go in the back yard etc it will affect him and he is your priority.

cheers
