How do I monitor my dog’s temperature to predict labor?

Monitoring your dog’s temperature is a reliable way to predict when labor is imminent. A dog’s normal body temperature ranges between 101 and 102.5 degrees Fahrenheit. As labor approaches, her temperature will drop significantly, usually to around 98 to 99 degrees Fahrenheit, indicating that whelping will likely begin within the next 24 hours. Here’s a detailed guide on how to monitor your dog’s temperature effectively and what to expect during this process.

1. Understanding the Temperature Drop
The drop in temperature occurs due to hormonal changes that prepare the body for labor. Progesterone levels decrease, which triggers a drop in body temperature and signals the onset of labor. This temperature drop is a natural and predictable part of the process, making it a useful tool for anticipating when your dog will give birth.

2. How to Take Your Dog’s Temperature
To monitor your dog’s temperature, you will need a digital rectal thermometer designed for pets. Lubricate the thermometer with a pet-safe lubricant or petroleum jelly to ensure comfort and ease of insertion. Gently lift your dog’s tail and insert the thermometer about one inch into the rectum. Hold it in place until it beeps, indicating the reading is complete. Record the temperature each time you take it to track any changes.

3. Frequency of Monitoring
Start monitoring your dog’s temperature about a week before her expected due date. Take her temperature at the same time each day, ideally in the morning and evening, to establish a baseline. As you get closer to the due date, you may want to increase the frequency to every 4-6 hours to catch the temperature drop as soon as it happens.

4. What to Expect During Labor
Once the temperature drops, labor typically begins within 24 hours. The first stage of labor involves uterine contractions and may last 6-12 hours. Your dog may appear restless, pant, or seek a quiet, comfortable place to nest. The second stage involves active pushing and the delivery of puppies. Each puppy is usually born within 30-60 minutes of active labor, though there may be breaks between puppies.

5. Potential Risks and Concerns
While monitoring your dog’s temperature is generally safe, there are a few risks to be aware of. Inserting the thermometer too forcefully or without lubrication can cause discomfort or injury. Additionally, if your dog’s temperature drops but labor does not begin within 24 hours, this could indicate a problem such as dystocia (difficulty giving birth). In such cases, contact your veterinarian immediately.

6. When to Seek Professional Help
If your dog’s temperature drops but she does not go into labor within 24 hours, or if she shows signs of distress such as prolonged straining without delivering a puppy, seek veterinary assistance. Other red flags include a foul-smelling discharge, lethargy, or a temperature that rises above 103 degrees Fahrenheit after the initial drop.

7. Long-Term Care and Prevention
After your dog gives birth, monitor her and the puppies closely for the first few weeks. Ensure she has a clean, warm, and quiet space to nurse and care for her puppies. Provide her with a high-quality diet to support milk production and recovery. Regular veterinary check-ups for both the mother and puppies are essential to ensure their health and well-being.

8. Additional Tips
Keep a whelping kit ready with supplies such as clean towels, a heating pad, and a scale to weigh the puppies. Familiarize yourself with the signs of labor and have your veterinarian’s contact information readily available. If this is your dog’s first litter, consider consulting with a veterinarian or experienced breeder for guidance.

By carefully monitoring your dog’s temperature and understanding the signs of labor, you can be well-prepared for the arrival of her puppies. This proactive approach helps ensure a smooth and safe delivery for both your dog and her newborns.
