Have you personally tried to get one in Panama?
thread about whites and Z's in the Health and Nutrition section,
they aren't allowed in the show ring.
Ok, I checked out the thread you mentioned (yes, the entire thread), and there is NOTHING stated about Z Factored Dobes not being allowed in the Breed Ring!
There is NOTHING in the Conformation Rules & Regulations or the standard stating a Black, Red, Blue or Fawn Z Factored Doberman cannot compete in Conformation. (If there is, by all means, please send me the info).
No, I have never tried to show a Z Factored Dobe, I don't own one. I'm fairly new to Conformation and have shown my female in a few different venues in which she's earned 4 titles as well as her AKC CGC by the time she was 2.
My point is, if these breeders producing Z factored litters feel they are improving the breed or doing the breed any justice at all by breeding Non Z to whites, why aren't they trying to show them? If it is for the fact that the registration #'s are listed in the catalogs and everyone else there will know the dog is Z factored that bothers them or keeps them from entering, then obvously they don't believe in what they are doing.
In this forum and many others I see White & Z Factored breeders boasting about "Beautiful Conformation". If they don't get them out there to see how they stack up to non-Z factored Dobes, it's just called Kennel Blindness.
