I think each female has to be looked at individually. Some females can safely have 4 to 5 litters in a life time and others might have difficulty having one. I think whelping is much harder on the smaller bitches (5 lbs and under). If a female requires a c-section then that females probably should not be bred again, depending on the reason for the c-section. Once a female has had two c-sections then I definitely feel she should not be bred again. The safety and well being of the female should always come first.
Most females are retired at age 5. |
