Yes there is an 'affix' - not sure if I can say what it is - but a search on COL and Google does not bring any thing up.
I'm not too knowlegeable in this area but someone on here will point you in the right direction,
This is a question for the people in the know - is there anyway by looking at the KC web site you could get any inkling about the said breeder of Dexter and Dillion? (Or dig deeper in to past etc)
I feel that if you want to go ahead you should really do a lot more searching into this breeder or as others have said walk away and look for another breeder.
Good luck with what ever you decide - please don't think we are all putting you or your decision down we are just trying to help you in getting healthy pups
and save you from a lot of heart ache. What ever you do we will help you with any problems and questions you may have along the way.
I personally have found this site a life line when I thought things weren't going as they meant to etc and to be able to ask questions of people with more experience with cockers is a great benefit
