I agree with Bruce, no matter how healthy the bitch may appear by just "looking" at her, you have no idea of the condition of her uterus. We will only breed our bitches up to the age of 7, never after that. 9 is definitely way too late to be breeding her, risking her life and also that of the potential puppies.
Does the person who owns her belong to a COE club? If so, they should know better! They should be ashamed of themselves for even considering a breeding at this age.
