From my understanding white coats in breeds such as Dobermans and Boxers = genetic problems.
Breeders years ago used to cull these pup's at birth and would never sell the pup's. Now, they have become a designer type dog, something nobody else has...rare..
. Not rare, just not a desired color as most are cursed with bad genes, flaws, skin problems, auto immune disorders etc. White Boxer's suffer the same genetic weakness as the white Dobe.
White Dobe's and Boxers usually means the gene pool is getting really really tiny and it's time to stop linebreeding that line and outcrossing from different lines of Dobes. White Dobes should NEVER be bred and you could never show a white Dobe in a CKC or AKC show. When seeing a White Dobe you are looking at a bad breeding problem that wasn't swept under the carpet.
This is just what I have been told, but, I'm sure if I took the time I could find documents to back me up.
I have attended plenty of dog shows, and as far as I know there is no minimum age you have to be to watch a show.
And why does me being 16 justify you to give me crap?
As for young people competing in dogs shows...I am sure you can be very young and handle a dog. I'm not a big dog show person as I think of them as just beauty contests and not really doing any good for purebred dogs at all.
In fact my Sister just got back from a show in Bermuda and a young boy under 16 was cleaning up the show and got BIS on one of the days. My Cousin started showing and handling and competing in obedience trials when she was 13 with the CKC. She was young and cute and got the attention of the judges (we all know that most judges are very much apt to put points on the handler and not the dog). A friend of mine could take a black dog from the animal shelter and get best in breed for Newfoundlands...(just a joke, but it hits close to the truth)
