STUD INQUIRING

We've found that using this IDEXX chart is the BEST way in which we go by for breeding.    

Many breedings are done guessing when is the right time and is done far too early and result in misses. Investing in progesterone testing minimizes misses based on timing. Chances are greater in getting a successful litter, we will not agree on a breeding without doing so.  Please follow this chart and give to your veterinarian when planning for a breeding. 

You can usually wait to do the first progesterone number on the 8th day, if caught early.

Do not stop testing until you've reached a number over 5. 

 

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 if vaginal smear is OK and bitch is still receptive. This is considered LATE if you still have to ship semen. Hope for the best. 

Not much can be determined by the numbers after 5, but you should not determine a breeding date until you get a number 5 or over.
