Cytology Swab Testing

Vaginal cytology is a procedure performed on female dogs during their estrus cycle, the stage when the female is on heat. It is a quick painless process for your dam. All care is taken and the welfare of your dog is always a priority. A swab is taken of the cells lining the vagina and analysed under a high tech, specialised microscope.

Progesterone testing

In order for me to carry out Progesterone or Reverse Progesterone tests on your dog you must provide a blood sample taken by a qualified vet, I can also arrange this service through my own vet. The sample can be brought to the clinic in person or by post.

This is a blood test which measures progesterone levels, a progesterone level of 16.00nmol + triggers the release of eggs (ovulation) the eggs are only fertile for four days. Progesterone is vital in sustaining a pregnancy to the full 63 day term. If levels drop below 10ng during term the pregnancy will fail unless supplemented. At around 63 days from the point of ovulation progesterone levels drop to below 2ng which is when labour begins.

Reverse progesterone test

Once pregnancy is confirmed by ultrasound scanning you will be counting down the days. Until the due date depending on the breed a c-section may be required, this test is vital in determining when this is, as if done too early before the lungs have developed enough could be fatal, once levels have dropped below 3ng it is safe. You can expect early signs of labour to begin once below 2ng. Under 1.40ng and you could expect birth within 12 hours.
