The oestrus cycle or heat cycle is monitored with progesterone testing. It is a blood test that helps us determine when ovulation occurs and the most optimal time for insemination. In house progesterone testing can be performed any day of the week and usually takes 60 – 90 minutes for a result (Note: Different hospitals may use different machines and careful interpretation is required).

Sometimes, the results are not consistent and your veterinarian may recommend additional procedures such as a vaginal smear or vaginal scope to assess for signs of oestrus/heat.
