Penny, whom is my first Yorkie, is going to be 4 years old this year. I, at the time, didn't research the breeder and rushed into buying the first Yorkie I saw. I knew better once after I got her. What I can remember, her dad had a lot of white in him and my first thought was Biewer color? At the time, I didn't know much about parti or biewers. He kept a 2 pound girl from the litter before Penny and I remember her having a lot of white in her too. I asked him if they were the Biewer color and I don't think he knew what I was talking about. Well, I have lost his number and would love to go and visit to see if they are indeed parti colored. For some reason, I'm thinking I was imagining it? I'm pretty sure I wasn't. So, I have his address on her AKC form, now is there a way I look up his number? Does AKC have the record and I can look into the database? I don't want to just show up at his doorstep. What if they moved?
Any advice and suggestions are welcomed!

Thanks in advance!
