My wife has shown dogs at several major shows throughout Canada and the US but have never been to the Westminster show herself. One of our " House dogs" is a former US and Canadian National Champion Silky Terrier. Two years ago, we leased her to a breeder in Boulder, Co for a litter. I will say that I would like to be able to sell flushes in some of my cows for what she received for this.
Like anything else that can be shown competitively, lots of games are played. In many cases, it is not so much the dog, or the owner, but who gets the highly paid dog handler who sees success in the show ring. I have met a few of these people.... and let's just say, some of them have changed my definition of weird!
We have a large international Arabian show near here each year and it is worth a trip just to see the pomp and pagentry that is presented there. One of my vets has been a resident vet at this show for several years now. Each year he come home and says that next year he is going to be the official cocaine dealer for the show rather than the vet. Guess it works quite well to get a high strung horse even more high strung when they enter the ring with nostrils flairing and eyes looking wild. I imagine a little makes it way into the nostrils of the owners as well!
