Progesterone Testing will tell us when the optimal dates for breeding your bitch.  It will also tell us exactly what day your bitch will deliver her puppies (63 days from ovulation or 5.0 ng/ml).

Many times breedings do not take because it was done too early or too late. We minimize failed breedings or "misses" based on timing.

Use the chart below and be sure to give it to your veterinarian when planning for a breeding.

We reccommend doing your first progesterone number on the 8th day of your bitches heat cycle (this is 8 days after the first day she begins to bleed. Continue to testing until you've reached a number of 5 or higher.

Below 1.0 ng/ml - no ovarian activity
ACTION: Test every 3 or 4 days

1.0 to 2.0 ng/ml - rise indicates active ovary
ACTION: test in 2 to 3 days\

2.0 to 4.9 ng/ml - active ovary 
ACTION - Test every 24 hours until you determine 5.0

5.0 ng/ml OVULATION

5 to 6 ng/ml - ACTION - Breed in 2 to 3 days

6 to 11 ng/ml - ACTION - BREED in 1 to 2 days

11 to 19 ng/ml - ACTION - BREED TODAY

OVER 19 ng/ml - ACTION - BREED IMMEDIATELY!
This is considered LATE if you still have to ship semen. Hope for the best.

Bottom Line is that your bitch will ovulate at 5 ng/ml and needs 48 hours for the eggs to mature.  You then have about a 72 hour window of opportunity to get her eggs furtilized.
