Using the links you already gave, I countered their assertions, and now using your link to the RSPCA I find 47 Lurchers, but only 35 Staffies listed.
You're not being clear, what are you looking at, a snapshot now or data for the past yeas? Again moot, as you can see there are plenty of Staffies.
I already explained the relevance to the point you were trying to make and why your inclusion of this headline assertion is only detrimental to that point.
No, you haven't, you've gone off on some tangential point that has little relevance - what do tales of your wife being apprehensive about adopting from a shelter have to do with the point I made?
I can see you have a bee in your bonnet about that topic but it doesn't negate the point made and I'm not just relying on headlines this is something noted by various rescue orgs.
And again, it doesn't actually matter if in the last year they're now in 2nd or 3rd positon, the point still stands. If it doesn't explain why?
