I think that dogs are pretty 'distinct' as individuals anyway, to be perfectly honest.

I don't have anything against pedigree dogs- I just could not understand the hostility that any mention of cross-breeds seemed to evoke.. It's as if anyone interested in a mixed breed dog was an idiot who had no concerns for animal welfare (I've seen numerous condescending and aggressive comments on this and other forums, regarding this issue) and it did puzzle me.

However, I've actually just this second finished watching the Pedigree Dogs Exposed documentary on Youtube - and I have to say I think I now understand the politics of this situation a little better.
