DH and I used to like to watch those shows. Then we picked up a "pet quality" GSD from a show breeder. At 6 weeks she was half-sized, so even though everything else about her was perfect, she was supposed to be a 40lb GSD. . .when it becam evident at about 4 or 5 months to the breeder that she wasn't "pet quality" (she caught up in size) but one that the breeder should've kept back for show, the breeder tried to get us to show our baby.
Well, we got a real education into the world of show dogs.
Annnnnnnddddd what those puppies go through? What the show folks do to win? Makes the kids and the moms on Toddlers and Tiaras look like sane, well-adjusted, normal people with a low-cost hobby that doesn't sap their free time.
Needless to say, our GSD is a couch potato. We don't kid ourselves, she's pretty enough that people who know the breed stare at her, but there are a LOT of pretty GSDs in the world; there's only one big ole' Mess in our lives and I couldn't do that to her!
(Now, agility, obedience and rally-o along with herding trials are things I could watch all day and can absolutely support. Our Mess did agility for a while and loved it. But not the dog beauty pagents.)
Just MHO. You're perfectly free to disagree!
