>I thought prog testing was super reliable? These comments are a bit worrying
Dogs don't read the books. And there are a few problems. First - The problem is that the test can only tell you where the dog is at on the day the test is taken. And you will get that result not immediately. For me, it was the afternoon of the next day. But I couldn't get a test done on Saturday because then Sunday was the next day and there was no point waiting till Monday to get a result. And I of course couldn't get a test done on Sunday either because the vet was closed. So really I could only test Monday to Friday. And bank holidays really mess things up.
Second, the test result will come with some kind of "advice". Like test again in 3 days or something. That is based on the average dog. Dogs don't read the books and they can progress much faster than this.
Our dog was tested on day 5 at 1.1nmol - that was a Tuesday which was really low. The advice given was to test again on Monday. So we did. But as that was day 11, I was nervous not to travel to the stud by then. So we decided to just get ourselves near him. So we did the test on Monday, day 11 as advised but then immediately travelled and got a mating the next day, day 12, Tuesday - with a 20min tie, easily.
Then we went back to our accommodation and got the result from the day before's progesterone - which was (from Larry at Idexx):
"Progesterone result is 4.9 nmol/l.
So she hasn’t ovulated, and resampling on Thursday indicated."
So you can imagine my distress, feeling that I just did a breeding for no reason because we were too early. We were now away from home and rather than take her to an unfamiliar vet for the progesterone, we decided just to wing it. We put the 2nd mating as late as we could before we had to return home - which was day 15 - Friday. The stud owner thought she was less into it and was about to go over, but we got another 20min tie.
When she whelped, I counted back the number of days to the start of anestrus ('going over') - which is v reliable - and found that she went into anestrus on either that Friday or (latest) the Saturday.
If we had tested on Thursday as told to by Larry, we would not have got the result until Friday afternoon - and we wouldn't have been able to arrange to rush to the stud instantly that afternoon. We probably wouldn't have made it there before Saturday, when she would have gone over. And if we had stayed home with our familiar vet to continue progesterone testing on Thursday, then there's no way we could have gotten to the stud in time.
I've run this past a few people and there's absolutely no way she can have gone from 4.9nmol on Monday to anestrus on Friday or Saturday, so the only conclusion is that somehow the progesterone was wrong. Whether that was IDexx which screwed up, or something my vet did with the bloods, I've no idea.
I'm just glad I didn't rely on it.
Next breeding, I didn't do progesterone and we just bred day 12 and 14, got 2 ties and 6 pups. My preferred approach really is just to hang out near the stud and try every 48hrs right through from day 10 on. But not many stud owners want to be doing that these days because it's quite time consuming. I realise some dogs ovulate really early or really late, but the vast majority are in the middle on most cycles.
PS I should add that on the 2nd progesterone test we did, the vet had to stab her about 20 times or something to find her vein and she ended up with a haematoma. It was all quite stressful. They had to take her away round the back to put pressure on it so it would stop bleeding. And it took forever for the hair there to grow back...
