As a exhibitor/breeder I would never breed a girl for the first time after the age of 3 and never breed a girl at all after the age of 5. After the age of 5 there are more chances for things to go wrong; genetically with the pups as well as for the dam.
Your girls are still young....too young to think of replacing them.....spay them and neuter your male.......
