Dog Pregnancy Week by Week: A Comprehensive Guide to Your Pet's Gestation

Welcoming a new furry bundle of joy into your family is an exciting and rewarding experience. Understanding the stages of your dog's pregnancy will help you provide her with the best care and support throughout this special time. This comprehensive guide will take you through each week of dog pregnancy, highlighting important milestones and providing essential tips for a healthy gestation.

Week 1: The Ovulation Phase

The first week of pregnancy is known as the ovulation phase, during which the female dog's eggs are released from the ovaries. The fertile period typically lasts for 5-7 days, with ovulation occurring near the end of this period.

Week 2: Fertilization and Implantation

During week 2, sperm cells travel through the female's reproductive tract and fertilize the eggs. The fertilized eggs then travel to the uterus and implant in the uterine lining.

Week 3: Cell Division and Early Pregnancy Symptoms

In week 3, the fertilized eggs begin to divide rapidly. Early pregnancy symptoms, such as swollen mammary glands and nausea, may become noticeable.

Week 4: Embryo Formation and Heartbeat Detection

The developing embryos begin to take shape and form distinct body parts. The heartbeat can be detected using an ultrasound scan.

Week 5: Rapid Fetal Growth and Appetite Increase

During week 5, the fetuses grow rapidly and their organs begin to develop. The female dog's appetite will increase to support the growing litter.

Week 6: Fetal Skeletons Form and Gender Determination

The fetal skeletons begin to form, and their gender can be determined through ultrasound.

Week 7: Weight Gain and Fetal Activity

The female dog's weight will start to increase as the fetuses grow. Fetal movement may become visible as the puppies kick and move inside the womb.

Week 8: Fetal Development Completion and Nesting Behavior

By week 8, the fetuses have fully developed their major organs and body systems. The female dog may start to exhibit nesting behavior, such as gathering blankets and pillows.

Week 9: Preparing for Birth and Ultrasound Confirmation

The female dog's cervix begins to soften and dilate in preparation for birth. An ultrasound scan can confirm the number of puppies in the litter and their estimated due date.

Week 10: Labor and Delivery

Labor typically lasts for 6-12 hours and involves three stages: contractions, expulsion of the puppies, and expulsion of the placenta.
