How To Tell if your Dog is Pregnant

How to Tell if Your Dog is Pregnant

How can I tell if my female dog is pregnant? Miranda shares dog pregnancy signs to look for, both physical and behavioral:

  • The best way to diagnosis a dog pregnancy is always with abdominal ultrasound which typically involves a visit to your veterinarian. For breeders that would like to learn to do this at home we do offer a wonderful option from Pet Tech Solutions. 

  • /products/vis-scan-x-ultrasound-system

     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. I have personally had puppies on the ultrasound that are not viable. The draw back to the Relaxin Blood tests is they will still be positive until the the placentas are gone.

  • Another way you can test for Pregnancy is Relaxin Blood tests. This is most reliably tested for starting 28 days past Ovulation ( not breeding)

    We offer two different Relaxin Tests

    The first one is done at home using a lancet under their lip.


    The other is a basic relaxin blood test, however, this involves a blood draw and you will need to have a centrifuge to spin the blood down. 


BUT REMEMBER IT RELAXIN PRESENT DOES NOT INDICATE A HEALTHY PREGNANCY. It just tells you that there are potential embryos. A see a lot of people say they had false positives. And as someone that uses both relaxin and ultrasound I can honestly say I think more times than not it was a reabsorbed pregnancy unfortunately. 

  • You can  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.
  • A lot of people count on the color of the dog’s nipples. Some female dogs 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 canine pregnancy. It’s really common, but not every dog does. 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.
  • The other really reliable indicator of dog 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.
  • 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.

What Do I Do When My Dog is Pregnant

The typical dog pregnancy lasts 63 days, plus or minus 48 hours. That means she will be whelping before you know it! We recommend using our Whelping Kits and Supplies to help you feel confident that you have all the whelping supplies you will need when the time comes for her to deliver her litter.
