I think one of the things we fight against is the indoctrination we've all had for years. Even now, when someone says "pit bull", I can feel myself wanting to create distance before my brain kicks in and tells me what an idiot I am. Pit bulls are so normal in the USA and make wonderful, kind, gentle, loyal family dogs - there is no reason they should be any different here. And Staffies in the UK are really normal - my sister had one - yet here, they're a PPP and so people have that slight cringe. I can understand the drive to want to keep you and your family safe, so it's not that I don't get it, I just think it's very unfortunate that we're programmed to feel certain ways about different breeds based solely on our geography.
If I had young children, would I be more hesitant to bring a labelled "potentially dangerous dog" into the family, rather than any other of the thousands there are to choose from? Probably, even though it has no basis in logic. And that's something we have to work through.
With Dexter, I'm also catching myself reading too much in to his totally normal puppy behaviour before I can correct myself, simply because he may be PPP. He has normal puppy biting - although he's so keen to please that he is learning quickly that he gets a lot more attention when he's a gentle playmate. But because he may be PPP, I'm constantly scanning for signs of aggression (there are NONE) and worrying about what any potential family would think of his normal puppy behaviour. He can be a bit humpy with Squidge when he's overexcited - I know some people would label that as dominance and try to correct it because he may be a PPP and he can't afford to think he's "the alpha". All the nonsense we know differently, but it niggles away at me because he comes with baggage, not because of who he is but WHAT he is.
All this to say that, I consider myself reasonably well educated and yet still find myself having involuntary reactions based on a label. It's no wonder, then, that many others do, too, and shy away from any of these dogs who is labelled as a potential problem.
For now, we'll just keep an eye on how Dex develops and do what we can to make him as bombproof, sociable, and well-mannered as possible.
