Which effectively means it might as well be a DQ, since a dog couldn't be successfully shown in the UK with a trait so listed. The competition is too stiff.
When the US standard was formulated, I believe I've heard that the AKC wanted there to be a disqualification, so the undesirable colors were listed as a DQ. It makes it more in line with the country of origin anyway, since if they were just "undesirable" here, dogs of those colors would still finish.
Blue is a controversial color, since it is not possible for a blue dog to have the black nose required in the standard. It also wasn't in the original standard, it was added in the 1948 revision. It was very rare until recently, when it's become a fad color, to many people's chagrin. A blue Stafford has never finished a UK championship, since the competition there is too stiff for a dog with such an obvious fault to finish. There are plenty of US blue champions, though. Since it's pretty easy to finish a dog here.
Thanks for the info! I knew blues weren't easy to finish in the UK, didn't know that there were blue champions in the US, though. I guess it shouldn't surprise me since Saxon's grandfather, Ch. Yankeestaff Preachin' the Blues, was a blue fawn and a champion. I know it's mean, but I've never really been a huge fan of blues in the breed. Probably because I was involved in Pit Bulls before Staffords and unethical AmBully and Pit Bull breeders advertise it as "rare" and charge more for it, and because of all the health issues that go along with blue-blue breedings.
P.S. Thanks for bringing up the nose, I forgot to mention that nose and eye rims should be black.
