Two of our Cockers are parti. One Red/White and a Black/White, the other is Buff. I laughed at your chocolate comments, all these people wanted chocolate cockers after Oprah had two chocolate cockers. They are actually my least favorite color for the breed.
I was always partial to tri colored cockers until I saw my first parti. They are so pretty and flashy. And, even tho I have goldens, I gotta say there is not much cuter than a parti colored cocker puppy. I would have a cocker, but I just am not willing to do the coat (for show).
