Breeding dogs is an exciting and rewarding process, but it can also be complicated and challenging, particularly when it comes to determining the right time for mating. Fortunately, technology has made it easier for breeders to predict the best time for mating through the use of progesterone machines

In this article, we will discuss how you can use a progesterone machine to enhance your dog breeding program, from understanding the basics of progesterone testing to the benefits of using this technology.

Understanding Progesterone Testing

Progesterone testing is a method used to monitor the levels of progesterone, a hormone produced by the ovaries, in a dog's blood. The levels of progesterone increase during a dog's estrus cycle, indicating when the dog is most fertile and ready for breeding.

Traditionally, breeders have used behavioral and physical cues to determine when a dog is in heat and ready for breeding. However, these methods are not always accurate and can lead to missed opportunities for mating. With progesterone testing, breeders can accurately determine the optimal time for mating, increasing the chances of a successful pregnancy.

The Benefits of Using a Progesterone Machine

Progesterone machines are designed to measure the levels of progesterone in a dog's blood accurately. These machines use advanced technology to provide breeders with precise information about a dog's estrus cycle, allowing for a more targeted and successful breeding program. Here are some of the benefits of using a progesterone machine in your dog breeding program:

Improved Accuracy

Using a progesterone machine for testing the levels of progesterone in a dog's blood provides a more accurate measure of a dog's estrus cycle than behavioral and physical cues. This helps to ensure that breeders know precisely when to breed their dogs, maximizing the chances of a successful pregnancy.

Increased Efficiency

Progesterone testing with a machine is a quicker and more efficient method of determining the best time for breeding. This reduces the risk of missing the optimal time for mating and helps breeders to make the most of each breeding cycle.


Using a progesterone machine may seem like an expensive investment at first. However, in the long run, it can save breeders money by reducing the risk of missed opportunities for mating, increasing the chances of a successful pregnancy, and avoiding the costs of additional veterinary visits.

How to Use a Progesterone Machine

Using a progesterone machine is a straightforward process. Here are the steps involved in using a progesterone machine for progesterone testing:

Step 1: Collect Blood Sample

The first step in progesterone testing is to collect a blood sample from the dog. This is usually done by a veterinarian or a trained breeder.

Step 2: Run the Test

The collected blood sample is then placed in the progesterone machine, and the test is run. The machine will measure the level of progesterone in the blood sample.

Step 3: Interpret the Results

The results of the progesterone test will be displayed on the machine. The breeder or veterinarian can then use this information to determine the best time for mating.

Frequently Asked Questions About Progesterone Machine

How much does a progesterone machine cost?

Progesterone machines can range in price from a few hundred to a few thousand dollars. The cost will depend on the brand, model, and features of the machine.

Can I use a progesterone machine at home?

Progesterone machines are usually used in veterinary clinics or laboratories. However, some models are designed for home use. If you are considering using a progesterone machine at home, it is essential

What is the ideal progesterone level for breeding dogs?

The ideal progesterone level for breeding dogs varies depending on the breed and individual dog. Typically, a level of 5 ng/mL or higher is considered the optimal time for mating.

How often should progesterone testing be done?

Progesterone testing should be done regularly during a dog's estrus cycle to monitor the changes in progesterone levels. The frequency of testing will depend on the breed, age, and health of the dog, as well as the breeder's breeding goals.

Can progesterone testing help diagnose health issues in dogs?

Progesterone testing is primarily used for determining the optimal time for breeding. However, abnormal progesterone levels can sometimes indicate underlying health issues in dogs. If you have concerns about your dog's health, it is best to consult with a veterinarian.

In summary, using a progesterone machine is an excellent way to enhance your dog breeding program by improving accuracy, increasing efficiency, and reducing costs. Progesterone testing provides breeders with a more precise measure of a dog's estrus cycle, allowing for a more targeted and successful breeding program.

While the cost of a progesterone machine may seem like a significant investment, the benefits of using this technology can result in significant cost savings in the long run.
