This is your answer in a nut shell.
Try and name 20 people who are actively campaigning Chocolate labs in field trials? When I say campaigning I mean running at least 15 trials a year. The percentage has to be based on participation and there are only a handful that have devoted this amount of time. On a side note everyone I know that is has a titled chocolate.
As Dr. stated. There is less color prejudice today but it is still there.
In obx4me"s example I believe that "serious" field trialers would take the black dogs first and they would be males.
If that same litter had 3 chocolate males I doubt if more than one would be placed in a Ft home.
The good news is at least more are making it to the game. 20 - 30 years ago you'd be lucky to see a chocolate at a trial let alone a FC.
Just my opinion.
Like Clinton said it depends what your definition of "is" is. HPW
West Coast, I personally know of 4 actively running brown dogs, 2 running Amateur, and 2 that are young; a QAA, who won't be able to be bred, and a derby prospect, very nice owners that are into brown. I bet they're more of the younger dogs, a certain female, her dad and her uncle have done a lot to change the people's opinions of brown. I just wish there were more to watch on the west coast circuit, there used to be, until everyone moved east.
Dr. Ed, The Trumarc line has contributed to at least one titled chocolate dog.
