Hi Guest,
Alison is quite right with her advice. Assuming that you poodle is KC registered, the best thing to do is to contact her breeder and ask his/her advice. If they are reputable they will let you know whether she is of suitable breeding standard, or has a too many faults (and all dogs have faults, even the top winners!) to make her a good breeding prospect - if she was sold purely as a pet she may not be. This does not mean she is not a nice dog - just not a potential broodbitch!
If she has sufficient merit the breeder will know which lines are likely to suit hers - some lines (families) while very good in themselves just do not mix well with certain others, and disasters can result.
You will also have to make sure she has passed the relevent health checks for her breed - Standard Poodles should be hip-scored (the average is 15), eye-tested and tested for Sebaceous Adenetis.
Hope this helps :)
