Replied on 04/19/2011. Most dogs have their first heat cycle at about 6 to 9 months, so I assume you mean months in your question not years. Female dogs are in heat for a period of 3 to 4 weeks.
For the most part, itâs better to wait until a dog is at least two years old before allowing her breed. You want to make sure her body is fully developed and can handle the strain of giving birth to a litter of puppies. Female dogs normally go into heat twice per year, with each cycle lasting approximately 21 days. A mature female dog may go into heat every six months, although itâs common to skip some cycles. The period is characterized by a swollen vulva, a bloody discharge and mood changes. Itâs important to note here that these changes only mark the beginning of a dogâs heat period; they do not mean sheâs ready to mate.
