Hi Sunniesmom;
As a newbie myself, welcome to the forum. I commend you on being such a young age and knowing what you want to do in your future. I believe you have set a very good goal.
As the others have previously told you do your research. Start as you are with one selected breed and visit the akc.org website. As for registering Sunnie with AKC that may be very very difficult. You would have a possibility of registering through ACA. Don't confuse AKC and ACA registrations. AKC is the oldest in which they are more interested with purebred pedigree which sets the standards for our little darlins. ACA tracks health breeding. A pup can be double registered, but be cautious of the kennel that does not offer AKC.
You will learn dogs that are AKC registered are eligible for AKC shows. This doesn't mean they will win, just that they can enter for a fee. Thats how all these champions are created. Hence the breeding stock and one reason why all the prices on these pups are so high. But now we deal with the USDA certified kennel only offering ACA registration. Their prices are just as high, only thing is these are the actual "pet quality". They can never be shown in AKC shows, unless they have a pedigree showing parents or grand parents registered. AKC can help with this.
Your on the right track honey, don't get discouraged. Just do your homework keep looking for the perfect pup that will meet the criteria of the AKC standard.
We all love Yorkies
