I would rather lose to a yorkie that is sound both in mind and body with a dyed silky coat...than lose to a fabulous natural coat on a dog with LP...narrow rears...poor topline...sloped shoulders...etc...like Donna said it is just the icing...
Now could I ever dye a dog?...I do not think so...I would never sleep...lol...
There is a story, not sure if it was ever posted here, and I can not remember the breed, it was a breed I was shocked to hear was colored in the ring...lol...but a young girl was handling the dog...took him in and won...when she was getting her picture taken with the judge, the judge commented on how nicely groomed the dog was...the girl replied.."thanks I colored him myself" ROFLOL...
There is a lot that goes on in any hobby and any sport for that extra advantage...there are several things I am sure some do that I have yet to learn about...but you have to take the good with the bad...
