I had not read RSPCA's actual announcement. Out of curiousity, I asked this:
What is a "disability" or "deformity" defined as, considering they are targeting the breed standards themselves?

Lucky, my heavy-coated, bracycephalic, low built dog, must be an abhorrent monster.
The response was this:
For sure, the short noses being bred to standard for Boston Terriers and other bracycephalic breeds would be at issue. From discussions with the vets I see regularly, I've learned the veterinary community is quite displeased with that development, they see more and more of those breeds coming in with issues as time goes on and the snout gets shorter. It is not Nature's way.
Perhaps I'm reading this wrong, but this implies to me that almost all breeds are not following "Nature's Way" and, thus, their standards should be revamped, as is also implied through this:
# An overhaul of the rules and requirements for pedigree dog registration and competitive dog showing (including breed standards).
An overhaul implies drastic change to me. I was given the impression that the RSPCA finds certain breed standards "unnatural" and thus aims to revise such standards - a feat I strongly disagree with.

That's what my objections are. I think there are a lot of things wrong with dog breeding today, especially involving the conformation arena. But revising standards is NOT the way to go.
