General Information from Dr. Hess
Progesterone low rise (<2 ng/ml) occurs with the LH surge. This happens 2 days before ovulation. Ovulation is indicated by progesterone level 4.0 5.0 ng/ml. The eggs remain fertile 2 3 days after ovulation. Breeding should begin 2 days after low rise; confirmed by progesterone rise above 4.0.

Notes from Julie's reproductive vet:
Every dog is different.
Ovulate from 4 - 10 ng/ml
Interpretive Comment from Chandra's
progesterone test
Ovulation Timing - Predicting the day of ovulation is best achieved by combining
serial progesterone levels and vaginal cytology samples. The time of the LH
surge can be estimated as the day that the progesterone concentration first
exceeds 2 ng/ml, as long as the progesterone concentration continues to rise
thereafter. Dogs will ovulate within 36 - 48 hours of the LH surge. The best
times for breeding are days 3 through 6 after the LH surge.

would be an added unnecessary cost she either has or wont ovulate
ultrasound is next step could run progesterone then.)

March 26, 2007 considered too far past ovulation to breed. Due to the weekend,
two days passed before these results were back. I attempted to AI in the
evening, but the collection was bloody (due to my own inexperience, Im sure). I
examined under microscope; found only blood cells.
March 29, 2007 AIed with fresh semen (Dorje) Collection and insemination went
well.
No puppies.

June 16 - 18, 2008 is her due date, according to Dr. Hess.
This is based on the ovulation date, determined by the progesteron rise above 5
ng/ml
on April 16th. Due date is 61 - 63 days after ovulation.
Chandra had colitis about one week after returning home from breeding. Knowing
about her possible pregnancy, her veterinarian gave her an injection
of ampicillian and Rx: amoxicillian, which were later okayed by Dr. Hess.
