The whole breed thing gets pretty stupid. The neighbors newly adopted rescue basset hound growled at me yesterday. This didn't exactly set my hair on edge. Later, while walking the neighborhood, I met another neighbor walking his pit. Now if that dog had growled at me it would have set my hair on edge. It's like the difference between a BB gun and a 45. Both are guns and can go off but I am not that scared of BB guns.
That's a fair way to put it.
The last time I was back in Iowa I went to my sisters farmhouse where her in-laws border collie-mix bit me in the back of the leg (drawing blood). This was after I had let it sniff me, and reached out my hand to try and pet it. Using some of the logic I've seen in this thread, I guess I should support a breed ban on all collies.
