How to understand a dog's pregnancy? - briefly
To understand a dog's pregnancy, observe changes in her behavior and physical appearance. Signs include decreased activity, increased appetite, and swelling of the abdomen. Additionally, a veterinarian can confirm pregnancy through palpation or ultrasound after day 28.
How to understand a dog's pregnancy? - in detail
Understanding a dog's pregnancy involves recognizing various signs and stages, from initial symptoms to the final delivery. Here is a comprehensive guide:
The gestation period for dogs typically lasts about 63 days, though it can vary slightly depending on the breed. During this time, several physical and behavioral changes may occur, indicating that your dog is pregnant.
Early Signs of Pregnancy (Days 15-20):
One of the earliest signs of pregnancy in dogs is a decrease in appetite or a change in eating habits. This can be accompanied by mild vomiting or nausea, similar to what humans experience during early pregnancy. Another notable sign is a change in your dog's nipples. They may become larger and more prominent, a process known as "pinking up."
Behavioral Changes:
Pregnant dogs often exhibit behavioral changes that can help you recognize their condition. These include increased nesting instincts, where the dog will start to prepare a comfortable place for her puppies by moving blankets or towels around. She may also become more affectionate and seek out more attention from you. Some dogs might display mood swings, being more irritable one moment and highly affectionate the next.
Physical Changes:
As the pregnancy progresses, physical changes will become more apparent. Around day 30, a veterinarian can usually detect fetal movement by gently palpating your dog's abdomen. By day 45, an ultrasound or X-ray can confirm the pregnancy and provide an estimate of the litter size.
Weight Gain:
A pregnant dog will gain weight gradually throughout her pregnancy. The amount of weight gained depends on the number of puppies she is carrying and her initial body condition. On average, a pregnant dog may gain 15-20% of her pre-pregnancy weight. It's important to monitor this weight gain and ensure your dog maintains a balanced diet tailored for pregnancy.
Preparing for Delivery:
Towards the end of the pregnancy, around day 58, you may notice a slight discharge from your dog's vulva. This is a sign that her body is preparing for delivery. You should also observe your dog's behavior closely during this time. If she starts to dig or scratch at the floor, it could be an indication that labor is about to begin.
Monitoring Temperature:
One of the most reliable indicators of impending labor in dogs is a drop in body temperature. A normal dog's body temperature is around 100-102°F (37.8-38.9°C). When your dog's temperature drops to about 97-99°F (36.1-37.2°C), it means labor could start within the next 24 hours.
Stages of Labor:
Labor in dogs is divided into three stages:
-
First Stage: This stage can last from 6 to 12 hours and involves contractions that help to dilate the cervix. Your dog may appear restless, pant heavily, and have a decreased appetite.
-
Second Stage: During this stage, which can take up to 12 hours, your dog will actively push out the puppies. This is the most critical time, as complications can arise, such as prolonged labor or puppy malposition.
-
Third Stage: This final stage involves the delivery of the placenta, usually within 10-15 minutes after each puppy is born. It's essential to ensure all placentas are delivered to prevent infection.
Post-Delivery Care:
After delivering her puppies, your dog will need plenty of rest and proper nutrition to support lactation. Regular veterinary check-ups are crucial to monitor both the mother and the newborns for any health issues.
By being attentive to these signs and stages, you can better understand and care for a pregnant dog, ensuring a smooth and healthy pregnancy for both her and her future puppies.
