If Your Bitch is Ready for Breeding
Females will have reached adult emotional development by the second or third heat cycle.
If your bitch is ready for breeding, your vet will examine her for good health and freedom from known inherited disorders.
Remember, do not breed from your dog simply "to satisfy nature." Pregnancy is riskier than not being pregnant- Helping to raise a young litter is a time-consuming and messy business.
It may be more difficult than you think to find homes for the resulting pups.
