Proestrus is the initial stage of the reproductive cycle and typically lasts around 9 days. During this time, female dogs may experience vaginal bleeding and attract male dogs, but they are not yet fertile.

Metestrus follows estrus and lasts for approximately 60 to 90 days. If the dog has successfully conceived, this is when implantation occurs, and pregnancy begins. Hormonal changes take place to support the growth of the embryos.

Diestrus is the stage when the dog’s body prepares for birth. It typically lasts for 50 to 60 days. The dog’s belly will visibly enlarge, and her mammary glands may start producing milk.

Anestrus is the resting phase of the reproductive cycle. It is a period of inactivity that lasts for around 4 to 5 months before the cycle starts again.
