The best way I can explain how to find the kennel names is by telling you what I did when looking for my breeder.
Go to the American Kennel Club website. There's a section titled "Events and Awards" and within that there is a search function, that allows you to find past events. You fill out what you're looking for (the state, what type of event- in your case it will be "conformation," and the time range- something like "from now to 3 months ago" should do the trick). From there, it will pull up a list of shows that occured within that time frame that meet your criteria. Click on the link on any one of the shows it's pulled up that says "view event results." Then you can simply click on the Sporting Group, and then Goldens.
It will give the names of Goldens that have placed. The kennel names will proceed each dog's name. For example- if I was competing with my Shiba boy (who is neutered, but that's not the point
) You would see his name as "San Jo Yuki Mai Tai."
San Jo is the kennel name, and is used on EVERY dog that the breeder breeds. When I was looking for Shiba breeders I noticed that locally, "San Jo" was popping up OVER and OVER again with BOBs and group placements. I had a pretty good feeling this breeder was producing some outstanding winners. So I met them in person, and went from there.
If you keep seeing "Goldspun" (just making up a name for the sake of the example), in front of winner after winner's name- you'll want to take a closer look at that breeder's program.
As a thirteen year old- you're the perfect age to start Jr. handling as well. This is a competition based PURELY on the presentation skills of the child handler, and has nothing to do with (or isn't SUPPOSED to have anything to do with) the quality of the dog. All you need is a purebred dog that belongs to you in order to compete. (It must be registered with AKC as well). It's a great way to start learning handling NOW, even when you don't have your Golden puppy.
If you don't have a purebred you can also try 4-H which does a similar Jr. handling competition, but allows mixed breed dogs.
I think it would be a great idea if you're interested. And would look VERY good to Golden breeders when the time comes.
