It means you did pretty darn good! Depending on how many dogs were entered, you should have at least one point towards your championship. If you are not sure, post how many dogs, male and female, were there, and what stae it was in, and I will tell you if your pup is now pointed. Also, was this an AKC show, or a match show, or a different country than the USA?
You need to have a long discussion with your handler! Especially if you are paying him or her! Your handler should have already given you answers to any questions that you have. Your handler should also be able to tell you how many points it was - entry numbers don't count. It's how many actually showed up.
If at least 11 of those 15 dogs showed up, your boy should have picked up 2 points towards his championship. Here is the link for the point schedule in your area. http://www.akc.org/pdfs/events/conformation/point_schedule/2007/division8.pdf
Hope this helps. BTW, CONGRATULATIONS! That's a mighty nice start for a show career.
