Introduction
If you suspect that your dog may be pregnant, it is important to confirm this before taking any further steps. While there are some physical signs of pregnancy in dogs, it can be difficult to tell for sure without a vet’s diagnosis. In this article, we will cover the definition of pregnancy, overview the common signs of pregnancy in dogs, and provide advice on how to tell if your pup is expecting.
Definition of Pregnancy
Pregnancy is the term used to describe the period of time between conception and birth. During this period, a female dog’s body undergoes many changes as the puppies develop. Knowing when your dog was mated can help you determine the approximate length of the pregnancy and when to expect the puppies to arrive.
Overview of Signs of Pregnancy in Dogs
The most common signs of pregnancy in dogs include morning sickness, weight gain, abdominal enlargement, changes in appetite, nesting behavior, increased aggression, and abnormal activity levels. While these signs can indicate pregnancy, only an ultrasound or x-ray from a vet can provide an accurate diagnosis.

Observe for Signs of Morning Sickness
Morning sickness is one of the earliest signs of pregnancy in dogs. This symptom usually appears two to three weeks after mating and can last up to four weeks. Common symptoms include vomiting, decreased appetite, and lethargy. It is important to monitor your dog during this time and make sure she is eating enough and staying hydrated.

Look for Weight Gain and Abdominal Enlargement
An increase in appetite is another common sign of pregnancy. As the puppies grow, your dog will need extra nutrition to support their development. You may also notice that her abdomen begins to swell as the puppies grow larger. This is normal and should not cause any discomfort for your pup.
Monitor Changes in Appetite
It is important to pay attention to your dog’s eating habits during her pregnancy. If she has been eating normally and suddenly begins to eat less or more than usual, this could be a sign of pregnancy. Additionally, if she starts to eat objects that are not food, such as toys or shoes, this could also indicate that she is expecting.

Pay Attention to Nesting Behaviors
As your dog’s due date approaches, she may begin to display nesting behaviors. This includes making a nest out of her bedding or other materials, pacing, and restlessness. These behaviors are normal and should not cause any concern. However, if they become excessive or disruptive, it is best to contact your vet.
Check for Behavioral Changes
During pregnancy, some dogs may become more aggressive or protective of their space. This is a normal reaction and should not cause any alarm. However, if the behavior becomes extreme or dangerous, it is best to contact your vet for advice. Additionally, some dogs may become more active during pregnancy, while others may become lethargic. Paying attention to any changes in your pup’s behavior can help you identify if she is pregnant.
Schedule a Vet Visit for an Ultrasound
Once you have observed the physical and behavioral signs of pregnancy in your dog, it is best to schedule a vet visit for an ultrasound. Ultrasounds are the most accurate way to confirm that your dog is pregnant and can also provide information on the number of puppies she is expecting. Additionally, your vet can provide advice on nutrition and care for your pregnant pup.
Track the Heat Cycle
Tracking your pup’s heat cycle can help you determine when she was likely mated. The average heat cycle for a female dog is 21 days, but this can vary depending on the breed. To calculate the cycle, count the first day she begins bleeding as day 1 and mark down the following dates as days 7, 14, and 21. If your pup is displaying signs of pregnancy and was mated within this timeframe, it is likely she is expecting.
Conclusion
In conclusion, there are many physical and behavioral signs of pregnancy in dogs that can help you tell if your pup is expecting. While these signs can give you an indication of pregnancy, only a vet visit and ultrasound can provide an accurate diagnosis. If you suspect that your dog is pregnant, it is important to take her to the vet for an ultrasound and follow their advice on nutrition and care during her pregnancy.
