If I were you I would seek out one of the best breeders, someone who sells dogs to others that gets made up and book a pup, even if you have to wait a while so that you're fairly high up on the list and then ask their advice in choosing a show quality pup. We spend a lot of money going to shows, you might as well have the best possible dog to show

I made up my very first show dog, when others who had been showing for years complained that it was cliquey and newcomers would never do anything. I spent a couple of years first going to shows, watching them and deciding what I liked and trying to work out why certain dogs were placed above others. I then decided on a dog that I thought was gorgeous, was very successful and his progeny were too, then I looked for a litter planned to him, a line bred litter. I was pretty low down on the list to choose though, actually I got the runt of the litter - but that well bred 'runt' won 5 tickets and a champ show group with a complete newbie to showing at the end of his lead.
Now I have a different breed, that are pretty rare in the UK with only 54 dogs here. Because I desperately wanted a silken, and was delighted with my first pup I showed her a bit though she has some very obvious faults, didn't do anything much with her. I got the chance of another silken, again I adore him but he's not really a show dog, he's had a few good seconds in open though. My star is a dog that I imported, I booked 2 years before he was born and was lucky enough to get pick of litter - that dog has just turned 2 and already has a reserve winners and a winners dog and a specialty best in show from the 5 shows he has attended (with 5x1sts). So I guess the moral is if you want to win you have to find the very best dog that you can to show.
Often people see 'big breeders' do well with their puppies and assume it's a face thing, more often than not though it's that they are very good at breeding and choosing the best pup, as well as being very good at preparing and showing them.
