Kennel Club agrees.Dangerous Dogs Act disagrees. UK Pit Bull Association disagrees.
Owner of this dog said it was a Pit Bull.
I had asked him if it was a Staff Cross or American.
I've taken other breeds to Crufts and I know a couple of dogs, and I've got eyes. I can spot most, and tell if they're good or not. Didn't like the Poodle that won Crufts this year. Not as good as Marita Gibbs' one, a few years back, and not as good as the Saluki this year, IMHO.
The only one I ever missed really badly was a Chesapeake Bay retriever (out walking locally), that I thought was Weimar Cross, possibly Weimar/Flatcoat or Weimar/Goldie. Owner was (rightly) very insulted.
