I also guess I'm old-fashioned and maybe set in my ways. I have a dog or dogs because they are first and foremost MY companions. Their tolerance of other animals comes secondry to that.
We don't see too many dogs around here. But go to Sheehan's Walk in Latrobe, and you are literally banging into a dog every five metres! That's where I will be taking Logan to test her tolerance and friendliness to other dogs.
