Firstly how do you know she is ready? Have you had her progesterone tested? If your relying on behaviour alone and both are maidens you may not get a mating.
To be honest it is best to take your (I assume fully health tested) maiden bitch to an experienced outside stud dog.
It is rare to have the ideal mate for your own bitch living with you unless he he was bought specifically to complement her good points and improve any weaknesses, and he has matured according to early promise.
As for your dog, if he has done well at shows and/or proved a good worker then people will ask to use him and his first bitch is best to be one who has had a litter or two and is steady and kind so that he gains confidence.
