Ovulation Detector FAQ’s

Is the Dog Ovulation Detector difficult to use?

The detector is very simple to use. If used per the instructions manual it will provide excellent results. Keeping the detector clean and disinfected is of the utmost importance. It should be disinfected BEFORE and AFTER each use. Any mucus left on the probe will give false results.

How should readings be taken?

The readings should be done once a day when ovulation is approaching and twice a day when values start to increase. Readings should always be taken the same way; it is best if the probe reaches the cervix. You will know you have reached the cervix when after gentle insertion you meet resistance. Ensuring that the probe is always inserted to the same depth every time you test is important. Otherwise you can insert the probe and take readings in different parts of the vagina and receive random, incorrect results. We also advise to always take the readings at the same time of the day, morning is best. There are several factors which may affect the readings otherwise, but errors can be avoided by taking readings at the same time every day.

What should I do if the readings are different than the manual?

The readings do not need to be the same as in the chart. Each dog may show slightly different readings. But it is important to find the maximum peak reading and the subsequent fall in readings. If reading values start decreasing ovulation is imminent. The best moment for insemination is when the readings fall close to the initial level.

Is there a way to check/test the device to ensure it is working properly?

When you press the switch in open air “1 0″ should be displayed. b) Prepare water-saline solutions with different salt concentrations, immerse the probe in these solutions and check whether the instrument responds to the changes in the concentration of salt. After the probe, has been taken out of the solution the result should constantly show in the display and should not disappear before 30 seconds (the switch must be held, of course). c) Check the instrument with 0,05 more KCL solution in 20°C. The instrument should display about 210-220 d). Make sure while checking the instrument that the electrodes (at the end of the probe) are clean and no “LO BAT” is displayed.

The readings are very high, is the device working properly?

Dirt, or skin oil on the electrodes will result in readings too high, whereas urine on the electrodes or solutions containing salt will cause lower readings. Please clean the electrodes and check if the device is working well, by following instructions explained above. Ensure to follow cleaning instructions in the manual to avoid damage to the probe sensors.

How should I clean the device?

Before and after each measurement, the detector must be disinfected. Careful and thorough cleaning and disinfection of the instrument is very important for proper usage. We recommend wiping the probe with gauze, cotton linen or even tissue paper to clean it of mucus, feces, urine or hair, especially around the electrodes. Next, it is best to wash it under warm, never hot running water and finally immerse it in a disinfecting solution. Always use disinfectants at concentrations given by the manufacturer, as if not used properly they may cause irritation of the vaginal lining. Wiping the probe clean before use will prevent this from happening.

What should I do if my device is not functioning properly?

Please check the device as described in the question: Is there any way to check the instrument? If it is not working as expected contact us.

Does the device work by measuring temperature?

It measures electrical resistance of the vaginal mucus located near the cervix which changes as the bitch moves through her cycle.

How accurate is the device?

It is very accurate and consistent when operated correctly.

Is it possible to harm a bitch during a test?

Not unless you are very heavy handed and do not take obvious care. Compare the size of the probe (length and diameter) to the penis of the dog (even in toy breeds). Gentle insertion of the probe is important to ensure the probe is inserted at the angle of the vagina and levelled off to reach the cervix (see How do you know if the probe is in the right place?).

How do you know if the probe is in the right place?

The probe should be inserted until a slight resistance is felt, which is when the probe just reaches the cervix. At this position, the probe tip is positioned within the area containing the maximum amount of mucus to thus obtain accurate and consistent readings. This position is adjusted slightly relative to the size of the bitch. Also, some bitches can be very dilated early in the cycle with little or no resistance being felt. Larger breeds will likely require the entire length of the probe inserted, whereas toy breeds will likely require less. If you have experience performing an AI, keep in mind the length of the tube inserted to reach the cervix or alternatively, consider the length of the male penis for the breed, that is a good indication of how far the probe should be inserted.

Mimic the angle of entry of the stud dog as he enters from underneath at approximately 45 degrees and then ‘levels off’. Remember that the vaginal passage has a kink in its shape. (Thus you need to enter at approximately 45 degrees and then level off as well). Sometimes early in the season, a few bitches may be somewhat dry. Moisten the probe with water, part the lips of the vulva and gently push the probe into the vulva. If the bitch constricts, hold the unit in place and do not push anymore until she relaxes, at which time you can resume gentle pressure, and the probe will slip into the passage easily. Do not use a lubricant such as KY jelly or Vaseline as they will adversely affect the readings obtained!

How often should readings be taken?

It is best to take readings daily at the same time of the day. When the figures start to rise, it is wise to take 2 readings a day to more accurately pinpoint the peak number and thereby determine the best time to breed. We suggest once every 12 hours, and be consistent, commit to every 12 hours, for instance 8 am and 8 pm. When readings start to rise, testing every 12 hours is helpful in pinpointing the peak reading and decline. It is suggested to not test more often as readings can fluctuate during the day, which can make graph interpretation more challenging. Stick to twice a day, at the same time each day to make result interpretation easier. Never repeat a test immediately following a test. By performing a test, you have discharged the mucous and another test too soon, will provide inaccurate results.

When should I start taking readings?

Take regular readings from the very first moment that you notice your bitch coming into season. Be consistent, sticking as close to the same time each day, makes for better interpretation of results.

For how long should the probe be inserted for?

After the reading stabilize on the detector LCD (takes approximately 2 seconds) the probe may be taken out of the bitch.

All the readings are low (no reading surpasses 200), what should I do?

Usually it is because the probe is not inserted far enough into the bitch and does not reach the actual mucus which is what the unit is looking to measure. Also, salt from the urine can depress the readings.

I am getting high readings randomly, why?

Usually it is because the probe is inserted too far. (the whole length of the probe is inserted up to the body of the instrument). Thus, going past the cervix and producing random high readings.

How can I tell the difference between a ‘false peak’ and a real peak?

The false peak can be just a small rise and fall or the rise can be quite significant. Regardless of the value though, it typically occurs around day 3/4/5 of the season.

My bitch still has some red discharge; however, the device indicates to breed, what should I do?

It is indicating what is happening with your bitch as opposed to the external signs, trust the device.

What is the probe made of? Will it break off?

The probe is made of a high-quality special polyamide plastic which is very durable.

Will the bitch mind the procedure?

All bitches are different, some accept the probe instantly without any problems the first time it is used, some are puzzled and some are uneasy, much in the same way as the reaction of a bitch to a stud dog when mating.

What should the maximum/peak reading be?

Some bitches peak reading may be 400, whereas others may be well more than 1000. The key point to remember is that you are looking for the profile (peak and drop) as opposed to the actual value of the reading.

My bitch did not peak at 600, I kept waiting and missed it!

The Manual explains that the peak value may be higher or lower than the example shown in the manual of a 600-peak figure. (Look for the peak followed by the decline in results). Each bitch will have her own unique results; the key is to pinpoint the highest/maximum reading and the decline in results.

When is the best time to mate?

Manufacturers state that the optimum time to breed is 24 hours after the peak.

Can lubricant be used on the probe?

Lubricant will adversely affect the value of the readings obtained.

Should I take the battery out when not in use?

No, the battery is only removed and replaced when it is exhausted.

How do you rotate the device while pressing the button?

You rotate the unit first and after a full rotation ~ THEN the button is pressed.

What happens with the readings once the bitch has ovulated?

The peak figure indicates when the luteinizing hormone is released, triggering ovulation to occur. After which time the value of the readings decrease steadily in a relatively short time and finally reach an approximate plateau figure at which they remain.

Can a bitch go through heat and not ovulate?

Yes, bitches can display ‘standard expected behavioral signs’ but not have what could be considered a ‘normal’ ovulatory season.

How will I know when the peak has been reached?

By taking readings regularly. Once readings start to rapidly rise, it is possible to take more readings in the day, however, ensure they are spaced out by at least 4 hours in between. When the values increase 2, 3 or 4 times a day a maximum peak figure is obtained.

Does diet affect the readings?

The manufacturer is currently researching this issue and believes that diet does affect the readings. However, once again it is not the actual value of the readings what is important but the profile that is obtained, to determine the peak figure.

Why do I get different readings when I push the button without moving the probe?

Because the electrical potential of the mucus initially tested has been discharged.

How will I know when the battery is low?

The LCD screen on the unit will show the message: LO BAT.

Will I need an assistant to help me when taking a reading?

No, but just as with breeding an assistant is helpful in reassuring and steadying the bitch.

How long will the device last?

With proper maintenance, it can last a lifetime.

How should I clean the instrument?

Disinfect the detector before and after each measurement. Careful and thorough cleaning and disinfection of the instrument are the most important conditions for its proper usage. Always use disinfectants at concentrations given by the manufacturer, as otherwise they may cause irritation of the vaginal lining. Clean the instrument before each use to prevent this. The solution of the disinfecting agent should be prepared directly before the next use of the detector. The best disinfectant agent is Hibiscrub, Dettox or Savlon solutions, or any other agent indicated for veterinary use. Wipe the surface of the probe with the solution, then rinse thoroughly with warm water (never hot water as it could damage the probe sensors), dry and store in its case.

Can I use the device when a bitch has problems?

Obviously, this instrument will not solve the reproduction problems of a bitch. It will not change an infertile bitch into a fertile one. However, it is another instrument to facilitate managing reproduction programs. This instrument can be used at home. It will reduce the number of visits to the vet as well as the number of more expensive and invasive tests. It will help to determine false heat because in such a case a value of the reading will not increase. Also in the case of quiet heat the peak of climax can be determined precisely.

Is it safe to test/use the probe after mating?

Yes, it should not have any adverse effects, however t is recommended to wait 24 hours after mating to use the device.

“I am very happy with both the Draminski Dog Ovulation Detector and the Draminski Pregnancy Detector. I have a very pregnant Calleigh and no huge vet bill! The money spent will pay for itself very quickly and they are so easy to use.”

Evelyn Chisholm, Kasamar Kennels, Ontario, Canada

“I have been breeding Bulldogs for over 25 years. I used all of the latest testing methods and did my own breeding slides. Since we also offer stud services I had a bitch who came to us and had a breeding problem. She had been bred twice before with a stud from another kennel. She even had an implanted surgical procedure done as the 3rd. attempt to get her pregnant with one of our studs. She was now 4 1/2 years old and never had a litter. I used the Draminski Ovulation Detector and my same stud, she conceived 8 puppies. I found that using the detector was easy but one must have patience when waiting for the correct time to breed. “
Carol Urban – Bulldog, Almont, Michigan, USA

“I must write to thank you for the ovulation tester, it is a real success. Normally technical things put me right off but this is so easy to use. I have had success with my bulldogs and also my Westies. So once again thanks for the wonderful aid to breeding.”

Dorothy Stephenson – Waldor Bulldogs & WHWT’s, Great Britain

“I think the ovulation detector is the best thing ever made. Before I purchased this unit, we had tried mating 2 bitches and every time they didn’t catch. I wasted nearly 2 years in keeping trying to mate them. So when I purchased the unit we found they were not ovulating properly due to fertility problems. Since then, my other two bitches have been tested and mated as indicated. One bitch produced 11 puppies and the other one 5 puppies. I would recommend the ovulation detector to anybody. It was well worth the money spent.”

Rickards – Jaggerhof, Rottweillers, USA

“I missed two previous seasons with my 5-year-old Bulldog both with apparently good matings. This time I used the Draminski Ovulation Detector and got 6 puppies. Thank you!”
R.D. Johns – Shin Tzu, Bulldogs & French Bulldogs, Great Britain

“It took a while for confidence to insert detector far enough into the vagina. Once over initial fear it was quick and easy to use and showed obvious peaks.”

Grace Brown – Sussex Spaniel, Great Britain

“We purchased the Ovulation Detector about a year ago and have used it on our mini Dachshunds with success. We recommend it.”

Sheila & Terry Raphael – Pennemma Miniature Long-Haired Dachshunds, USA

“Annie did not ovulate till real late into her season… if it was not for the ovulation detector I may have missed out on this breeding. I missed out on her last season because I did not know that she ovulated late… but I thank God I have this device now… I kept record of Annie’s ovulation every day and if I did not do that I would had missed out and if I had relied on a vet it would cost me a lot of money to have them to test her for ovulation… this device works and it is reliable.”

Kathy Wells – Servant’s Labradors, USA

“We are very pleased with the Dog Ovulation Detector. We have used it about twelve times (already !!!) with pleasure and success. At the first time we used it in the same time as another method (progesterone level test). The Dog Ovulation Detector confirmed each time the same ovulation day. We recommend to use this detector to the other breeders we know. The new version of our website, will show the Draminski Dog Ovulation Detector to present it as an appliance we use with good results in our kennel.”

Françoise and Claude Janzac – Cavalier King Charles Spaniels, Le Parangon du Roy, France

“I am very pleased with your product, thanks, I had missed twice before with one of my girls by getting the wrong day, but I just had it confirmed last night by scan that she is expecting at least 4 puppies! Your product worked fantastic for me, it was the first time I had used it.”

Carla Z. Martins – Cavalier King Charles Spaniels, Great Britain

“I recently purchased the ovulation detector after using a friends with excellent results. We’d bred three times before using the vets’ slides and absolutely NOTHING. One time with your detector and my English Bulldog had 10 puppies. So, I was hooked and purchased one.”

Karen Storrs – English Bulldog, USA

“I ordered your Dog Ovulation Detector for my griffons. I want to thank you a lot for this great instrument. I used it on my bitch Elinor that had no signs of estrous the day that was indicated as mating moment with your tester. The result – she conceived 5 puppies. Thank you again.”

Natalia Tabuyeva – Griffons, Tallin, Esthonia

“A friend has got one of these and he says they are fantastic. He said 21 days after mating he can even detect pregnancy using this instrument.”

Sean, South Yorkshire, Great Britain

I purchased both the Draminski Ovulation Detector & The Pregnancy Detector early last year 2015.
Both these tools have been of great value to my Breeding Kennels. Each bitch is tested daily that is in estrus and one bitch I would have missed who ovulated at day 6!!! Another never peaked until late in her cycle and if bred on the norm of day 12 then she would have been missed. It’s also been great to know when to travel to the stud dog at the right time. Having small dogs, it is easy to put them onto my grooming table and I reward them with a treat each time. They are very smart dogs and have it all worked out of the produce by day 3 and turn themselves around whilst I do the reading. The product has more than paid itself off already. I’m pleased to say I wouldn’t have some of the lovely puppies on the ground now if I didn’t have the Ovulation Detector.

The pregnancy Detector has also been great to use. And I use it on both my dogs and sheep. It’s helped with knowing if my bitches are in whelp prior to export or just for knowing if we are expecting puppies or not.

Anita-kaye Malby, Jacknthebox Kennels + Barrakee” Dorper Stud – Australia

We have used the ovulation detector once and as we also have a very experienced stud dog it was interesting to see how he related in his reaction to the data we were getting from the meter. The detector and the stud dog were completely in sync, as we were taking the bitch to a dog outside our yard this allowed us to time the mating very accurately and got 5 pups from the single tie. I have and will continue to recommend the detector to breeders and will be assisting a few breeders with some bitches that have in the past been very difficult to time their matings.

Ken Cox, Cadarnan Staffords – Australia

User Manual
Best Practices

Best Practices

Summary of best-practices using the Draminski Dog Ovulation Detector:
1. For the first couple of heat cycles, corroborate the Ovulation Detector results with progesterone tests or other tests which you’ve found to be reliable.
2. When taking daily measurements, ensure that you test at the same time of day for each reading.
3. The probe on the detector has been designed for use with all breed types and sizes. For safe and comfortable use, it is essential to read the User Manual, specifically pages 6 to 8, regarding the following:

a. Find the proper depth to insert the probe up to the cervical mucous (the area where you will find slight resistance inserting the probe).

b. Insert the probe at a comfortable angle, being approximately the 11 o’clock direction on a clock face (imagine the male entering the bitch coming up to her from underneath at an angle).

c. Take readings in the same position in the vagina for each test. This is essential for reliable results.
4. Record and get familiar with the unique readings for each bitch to observe the trend and note the highest peak reading. We suggest doing this for a few ovulation cycles to understand the range of values.
5. Clean and disinfect the probe before and after each use. Residue on the probe sensor, including urine or oil from your skin, leads to inaccurate results.

Identifying forthcoming ovulation using this proven method is effective and produces successful outcomes when applied correctly.
