10 Signs of a Pregnant Pomeranian

Pregnancy in Pomeranians, while a natural process, involves complex physiological changes and requires attentive care from the owner. Recognizing the early signs and understanding the gestational timeline are crucial for ensuring the health of both the mother and her offspring. Here’s a deeper dive into the signs of pregnancy in Pomeranians, incorporating more technical details and timing considerations.

1. Hormonal Fluctuations and Appetite Changes

The initial stages of pregnancy in Pomeranians are marked by significant hormonal changes, primarily involving progesterone and relaxin. These hormonal shifts can lead to variations in appetite. An initial decrease in appetite due to nausea, akin to morning sickness in humans, may occur in the first few weeks post-conception. As the pregnancy progresses beyond the initial 3-4 weeks, an increase in caloric intake is usually observed, necessitating a gradual escalation in food provision to support fetal development.

2. Mammary Gland Development and Nipple Enlargement

Approximately 3-4 weeks into the pregnancy, you’ll notice mammary gland enlargement as the body prepares for lactation. This development involves both the proliferation of glandular tissue and an increase in blood flow, leading to more prominent and darker nipples. This physiological change is in preparation for milk production, which is regulated by prolactin towards the latter stages of pregnancy.

3. Abdominal Distension and Fetal Growth

By the mid-point of the gestational period, typically around the 4-5 week mark, noticeable weight gain and abdominal enlargement become evident. This abdominal distension is due to the growing uterine size as the fetuses develop. Ultrasonography can be employed around this time to confirm pregnancy and assess fetal health.

4. Nesting Behaviors: Progesterone’s Role

As the expected whelping date approaches, particularly in the last week of gestation (approximately day 56-63), a pregnant Pomeranian may exhibit nesting behaviors. This instinctual drive, influenced by the hormone progesterone, prompts the mother to seek a safe and comfortable space for birthing and rearing her puppies.

5. Decrease in Physical Activity: Energy Conservation

Pregnant Pomeranians often show a marked decrease in physical activity, particularly in the later stages of gestation. This reduction in activity is a natural response to the increased physical burden of carrying a litter and serves to conserve energy for the birthing process.

6. Behavioral and Temperament Changes: The Role of Hormones

Pregnancy can induce significant behavioral changes due to fluctuating hormone levels. Owners might observe increased affection, clinginess, or conversely, a desire for solitude. Mood swings and irritability can also manifest, reflecting the complex interplay of progesterone, estrogen, and relaxin on the central nervous system.

7. Visible Fetal Movement and Advanced Abdominal Enlargement

In the final weeks of pregnancy, the abdominal enlargement becomes pronounced, with the possibility of visible fetal movements as the puppies become more active. This stage signifies that the birth process is imminent.

8. Pre-Partum Temperature Drop

A significant sign that parturition (the act of giving birth) is near is a drop in basal body temperature, typically occurring 24 hours before labor. This temperature drop, often falling below 99°F (37.2°C), is due to a decrease in progesterone levels, signaling the body to initiate labor.

9. Pre-Labor Discharge

A clear, vaginal discharge might be observed in the days leading up to labor. This discharge represents the expulsion of the mucus plug, indicating that the cervix is preparing for the birthing process. Any deviation in the color or consistency of this discharge warrants veterinary evaluation to rule out complications like infection.

10. Enlargement and Lactation Onset in Mammary Glands

Just before labor, the mammary glands further enlarge, and colostrum, the first form of milk rich in antibodies, may be expressed. This physiological change is crucial for providing the newborn puppies with essential nutrients and immune support immediately post-birth.


Pregnancy in Pomeranians is a complex physiological process that requires vigilant care and attention from the owner. Recognizing the signs of pregnancy and understanding the underlying biological mechanisms are paramount for providing appropriate care. Regular veterinary consultations throughout the pregnancy can ensure the health and well-being of both the mother and her puppies, facilitating a smooth birthing process and postnatal period.
