thanks a lot.

Answer
A bitch can become pregnant whenever she comes in season... no matter what her age is. In reality, they should not be bred before 18-24 months of age, and most good breeders retire their bitches around 5-6 years of age as the odds for having problems increases dramatically after that.

The oldest bitch I am aware of is one that came to me as a rescue so that I could help raise her puppies; she was 13 years old. And any bitch can most certainly become pregnant during her first season.
