Pregnancy Detectors for Dogs FAQ

How does the Pregnancy Detector work?

Tester detects the presence of amniotic fluid inside the uterus. Amniotic fluid indicates pregnancy.

How early can a pregnancy be confirmed?

The fetus presence can be confirmed even on 21st day after mating / insemination. The optimal time window is 25-28th day.

The tests can be done from 3 weeks until approximately 40 days after mating or insemination.The most accurate results are achieved between days 25 and 28.

If a test is carried out early, we advise that the test is conducted again between the optimum test period of 25 to 28 days.

Normal scanning time is 15 to 20 seconds or a little longer, but with practice, accurate test results can be achieved in a few seconds.

How do you use the Pregnancy Detector?

Place the probe to the right groin, direct it 40-45° head direction. Be aware of the urine bladder located towards the tail, giving identical signal as the amniotic fluid surrounding fetus.

How do you interpret the results?

The light and sound signal pulsating slowly (1/s) indicates proper probe contact with the skin. The light together with sound signal pulsating faster (up to 5/s) indicates pregnancy.

When is it ideal to begin testing for accurate results?

Testing can be performed from 3 weeks after mating. However the
optimal time for accurate diagnosis is between days 25 & 28, because of
the enlargement of the uterus at this time and its movement slightly
downward, closer to the peritoneum. Testing prior to day 25 is possible, but accuracy decreases due to insufficient amniotic fluid being present to reflect the ultrasonic waves.

Are there different settings depending on the size of the bitch?

Setting the potentiometer (gain control) correctly, is a very important factor, which influences the validity of the results obtained by testing.

Bitches vary in regards of weight and size for different breeds and thus the gain must be set to the particular position relevant to the size of the bitch that is being tested.

For ease the potentiometer has been calibrated to show:

  • S – for small bitches (Yorkshire Terrier, Chihuahua, Pekingese,Toy Poodle Dachshund, Papillon
  • M – for medium size bitches (West Highland, White Terrier, Border Terrier, Norwich, Norfolk Terrier, Fox Terrier, Shih Tzu, Corgi, Whippet, Cocker Spaniel, Lhasa Apso)
  • L – for larger bitches – (GermanShepherd, Border Collie, Rottweiler, Labrador / Retriever, AfghanHound, Standard Poodle, Doberman, Boxer, Dalmatian)
  • G – for the giant bitches – (Bloodhound, Old English Sheepdog, St.Bernard, Newfoundland, Bernese Mountain Dog, Irish Wolfhound)

With usage, familiarity and experience, the gain control can be adjusted to suit the particular bitch, both in terms of breed type and actual size, so that an optimum setting is achieved to ascertain accurate results.

Testing can be performed from 3 weeks after mating. However the optimal time for accurate diagnosis is between days 25 & 28, because of the enlargement of the uterus at this time and its movement slightly downward, closer to the peritoneum. Testing prior to day 25 is possible, but accuracy decreases due to insufficient amniotic fluid being present to reflect the ultrasonic waves.
