If the bitch's breeder is reputable and trying to breed good examples of the breed they will be more than happy to advise. They should know her bloodlines well, and which male lines may complement her. She may not be of breeding quality, and they should be able to tell you what her strengths and weaknesses are. If they do9n't tell him what the rfailings are as well as any good points, I would expect they are not very knowledgeable.
On the other hand if they are just a puppy producer they may not be interested in helping, or too interested in getting her mated to any old dog, and making something out of it!
Basically if she came from the second kind of breeeder it is doubtful if she is up to the quality needed for a brood bitch.
Lastly bear in mind that breading is a serious business caryying the responsibility for the lives produced. Sight hounds are a special group of sogs and are unsuited to most average pet homes. There is the grooming and the excersise and the need for a lot of careful training.
