484 – Five Ps in Passport to Successful Reproduction
Five Ps in Passport to Successful Reproduction Dr. Marty Greer, DVM, joins host Laura Reeves to discuss the five Ps in the passport to successful dog breeding. Progesterone “We need to start progesterone testing early enough and repeating the testing often enough and long enough to make sure that she's ovulate plus one test beyond that. So ovulation in most people's labs is going to be between four and eight nanograms per mil. “Be sure you start early enough and you go long enough that you've got one progesterone past five. If you stop at 4.7 and then she doesn't get pregnant, we don't know if she actually did or not (ovulate)… It's not only to get the breeding done successfully, it's also so that you can time when she's doing to whelp. “I cannot overemphasize the importance of progesterone timing. If nothing else, you're going to have the vet clinic on your side when you call, (instead of) saying, ‘Well, really I have no idea when she’s actually due.’ I don't know if you're overstating the crisis that you're in, if you're underestimating the crisis you're in, but without that data we really, as a veterinary community, don't have the information we need to start initiating early care to save your bitch to save your litter. Prenatal Care “We know from the human side how important good prenatal care is. There's a reason that women that are pregnant go to the doctor frequently. We need to monitor the bitch during prenatal care but even before she gets pregnant, we need to start folic acid 6 to 8 weeks before she comes into heat. We need to have her in an ideal body condition. We need to make sure she's on an appropriate diet that doesn't contain legumes, peas and beans. And we need to make sure she's on a diet that's got the macro and micro nutrients that she's going to need to be pregnant and sustain a pregnancy. “We want to make sure vaccines are up to date, because you can't vaccinate during pregnancy and if she comes due during the time she's pregnant, we cannot vaccinate. We want to make sure she's an appropriate heartworm and flea and tick preventives that are safe for breeding dogs. “We want to make sure that we've brucellosis tested her well enough in advance that if she comes back positive we can do the confirmatory test, because up to 10% of the brucellosis test will come back positive, and that can be a false positive. Now, that being said, it's easy to say ‘Oh yeah, brucellosis doesn't happen in the United states anymore.’ And guess what that's not true. Puppy Count X-ray “Take the X-ray somewhere between day 55 and a 60 of her pregnancy. “People say, ‘oh I'm not going to do that… it's not safe or it's not accurate…’ I'm going to give you some tips that can make it accurate. If you are taking X rays with a digital machine … it's very safe. The exposure to X-rays is very, very low. In fact if you live in Denver, where the altitude is high, you have the equivalent from sun exposure and radiation of five to 10 chest X-rays a year, just living in that environment. “Go to a vet that has a digital X-ray machine. Take your bitch fasting. She needs to not have breakfast the morning you take her in for the X-ray. (Make sure she has a bowel movement) before you go in, so her hair colon is empty because the more food and the more stool in the colon the harder it is for us to see the puppies on the X-ray. “We take two lateral X-rays, meaning that they lay on their side. We put them on the right side down and we put them on the left side down. I don't care what order you do it in, but I don't take them on their back. What's really cool about it is, many times you'll see seven puppies on first X-ray and you roll them over and an eighth puppy appears. (Most likely) they were perfectly aligned in the uterus and...
