Sorry but there is no possible way to tell, if neither dog has ever had an issue with other dogs than it's unlikely they'll fight. If either dog has had a history of dog aggression..well you probably shouldn't be setting up a doggie play date. You just have to find out by letting them meet.
Just supervise them very closely and make sure nothing can get out of control.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
