The older female is probably the dominant figure in your little pack. Your bitch has probably told him his place in the pack making it hard for him to overcome ...always buy your male first...females second. He may not ever breed her or if he does it will be difficult. However, to help with this...separate them when she first comes into heat and do not put them together until she is standing...about 10/13th day. Do not leave together long..and control your bitch by holding her head so she cannot give him eye contact...if he cannot get the job done within a few minutes, take him away again and repeat. sometimes bringing in another male will tease the first male into being strong.
