Shelley: Time for a Vet Minute with Revival’s Director of Veterinary Services Dr. Marty Greer. Dr. Greer the question is how can I tell if my female dog is pregnant? What are some of the signs to look for, both physical and behavioral?

Dr. Greer: I hate to say this but the best way to diagnosis a pregnancy is always with abdominal ultrasound which typically involves a visit to your veterinarian. There are some blood tests on the market, but I’m not a fan of those. The reason I like ultrasound the best is I can get an estimation of not only the size of the litter, but how strong the puppies look and if it looks like there are any abnormal puppies in the litter. But people want to try this at home, so some people will palpate or feel the dog’s abdomen. And if you choose to do that, you want to palpate or feel it very carefully because rough or too aggressive palpation can actually interfere with the placental attachments. We don’t want to in anyway jeopardize the pregnancy by manipulating the female too much. The one thing that everybody tends to overlook is the fact that all female dogs whether pregnant or not pregnant have a high progesterone. Every dog either goes through a pregnancy or a false pregnancy after she ovulates. So sometimes it can be hard to tell the difference because progesterone is one of the hormones that dictates the changes in the behaviors we see. So every female as soon as she ovulates, her progesterone rises and continues to rise and will stay high for 60 to 63 days, to the point that I’ve even seen some dogs go into false labor. It’s not common, but they’re so convinced they are pregnant that it can happen. So the important things to note are progesterone is always high, regardless of ovulation or not and every dog has a false pregnancy or a real pregnancy. A lot of people count on the color of their nipples. Some females will have a change in their nipple color. They will become a little big more prominent and more pink than they would be when she’s not pregnant. Sometimes they will even have sort of a candy corn stripe to them so you can notice the changes. I don’t typically see color changes in the vulva or skin around the vagina, but some people do describe that.

A lot of female dogs experience, and in fact it’s considered the most reliable change is a decrease in appetite between the third and fifth week of pregnancy. It’s really common, but not every dog does. I’ll have people come in frequently for ultrasound and I’ll say, so what do you think? And they’ll say “oh, she’s been eating like a champ!” And I’ll say, “ooh, that may not be good,” because I typically expect to see the appetite drop off maybe it’s just for one meal if it’s a Labrador, maybe if it’s a Cavalier King Charles Spaniel she’ll miss three or four meals before she starts to feel well enough to eat. And it may not always be in the morning. It might be morning, it might be evening, so we can’t always quite call it morning sickness. And then the other really reliable indicator of pregnancy is a clear vaginal discharge at the time that they’re more than three weeks pregnant. And we can see that up until the time they deliver. So a clear vaginal discharge is fine, if you see color to the vaginal discharge, red, green, brown, any kind of color that doesn’t look like it’s clear then that’s reason for concern and reason for veterinary intervention. So at that point, it’s important to go into the veterinary clinic, get a progesterone, get an ultrasound and see if the pregnancy is going appropriately or not. But like I said, every female has a false pregnancy so it can be sometimes hard sometimes will over interpret that information when we’re so excited that we hope that she’s pregnant.
