Introduction
The Draminski DOD2 Deluxe Dog Ovulation Detector is designed to assist breeders in identifying the optimal mating time for bitches. This device measures changes in the electrical resistance of vaginal mucus, which correlates with the estrous cycle. This method helps detect ovarian cycle disorders and determine the best breeding window, even when external symptoms are not clearly visible. The measurement process is straightforward and safe for the animal.
Key benefits include:
- Accurate detection of the optimal mating time.
- Reduction in the need for repeated mating attempts.
- Assistance in identifying 'silent heat' and ovarian cycle irregularities.
- Potential reduction in veterinary visits for cycle monitoring.
- Minimization of stress associated with unsuccessful mating attempts.
- Reduction of travel costs related to re-mating.

Setup
1. Battery Installation
- Locate the battery compartment on the device.
- Open the compartment cover.
- Insert the 4 AA-type 1.5 V (LR6) batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
2. Initial Power On
Press and hold the OK button or the ESC on/off button (as indicated on the device) to power on the unit. The display should illuminate, showing the current date and time, and allowing selection of operating modes (Basic or Advanced).

Below the screen are 'OK' and 'ESC on/off' buttons, along with navigation arrows. A long, white probe extends from the top of the unit, ending in a metallic tip. The brand name 'DRAMIŃSKI' is visible on the device body and a lanyard at the bottom.
Operating Instructions
1. Preparation for Measurement
- Ensure the device is clean and the probe is thoroughly disinfected before each use.
- It is recommended to conduct measurements at consistent times each day, ideally once or twice daily.
- Ensure the animal is calm and restrained appropriately for safe measurement.
2. Performing a Measurement
- Gently insert the probe into the animal's vagina. Ensure proper depth for accurate readings.
- Once inserted, perform a measurement cycle as per the device's on-screen instructions (e.g., press the OK button).
- The device will display a numerical reading representing the electrical resistance of the mucus.
- Record the readings daily to observe patterns and identify the peak ovulation period.
3. Interpreting Results
The device detects changes in electrical resistance. A significant drop in resistance followed by a rise typically indicates the optimal breeding window. It is crucial to monitor the trend of readings over several days rather than relying on a single measurement.
- Consistent Measurement: Take readings at the same time daily for accurate trend analysis.
- Graph Pattern: For some breeds, especially smaller ones, the absolute numerical values might differ from general guidelines. Focus on the pattern of the graph (if using the computer software) or the trend of numbers rather than specific high values.
- Silent Heat: The device is particularly useful for detecting 'silent heats' where external signs of estrus are minimal.
Maintenance
1. Cleaning and Disinfection
- After each use, thoroughly clean and disinfect the probe. Use an appropriate disinfectant solution or alcohol.
- Ensure no moisture enters the main unit.
2. Storage
- Store the device in its transport case with the foam insert to protect it from damage.
- Keep the device in a dry place, away from extreme temperatures and direct sunlight.
- Remove batteries if the device will not be used for an extended period to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly inserted batteries. | Check battery polarity. Replace with fresh AA batteries. |
| Inconsistent or erratic readings. | Improper probe insertion, insufficient disinfection, or inconsistent measurement times. | Ensure the probe is inserted to the correct depth. Thoroughly disinfect the probe before each use. Take measurements at consistent times daily. |
| Readings do not match expected ovulation levels. | Individual animal variation, breed-specific differences, or misinterpretation of data. | Focus on the trend of readings over several days rather than absolute values. Consult the detailed manual or manufacturer's guidelines for specific breed considerations. Consider combining with other ovulation detection methods (e.g., progesterone testing) if uncertainty persists. |
| Difficulty navigating menus. | Unfamiliarity with the user interface. | Refer to the detailed instruction manual for specific navigation steps. Practice using the OK, ESC, and arrow buttons. |
