Tests for Pregnancy in Dogs
There are a few different ways you can test your dog for pregnancy. Some people prefer to purchase online test kits and perform the tests at home, but these do take practice. Most times, especially for a first-time breeder, a veterinarian will be able to help with dog pregnancy tests.
That being said, the most accurate way to tell if your dog is pregnant is to have a veterinarian perform a blood test or an X-ray. A blood test checks the hormone (called relaxin) level in the plasma. This can be both expensive and difficult for dog owners.
An X-ray will be able to not only tell if your dog is pregnant, but how far along she is. It is important to note that you must wait 3 1/2 weeks before the vet can perform any sort of pregnancy test, or else the results will not be accurate.
It is also important to note that a human pregnancy test will not work on a dog. The hormones are different and the test will not read an accurate description.
Dog Pregnancy Test Kits
Although some people will argue that there is no specific test for dog pregnancy, you can purchase relaxin pregnancy test kits, which require blood samples done yourself. These kits can sometimes determine a real pregnancy from a false one. They work by measuring the level of relaxin developing in the placenta.
The only tricky part about the pregnancy kits is some require a blood draw and spin. Many people are uncomfortable with this, or do not know how to do it properly, therefor the test may be inaccurate or useless.
Costs Involved with Dog Pregnancy Tests
The cost to have a pregnancy test performed on your dog may vary depending on size and other considerations. A blood test usually ranged from $50-90$, but they do need to be performed more than once (up to 5 times).
Pregnancy kits may cost between $100-$200, depending on the quality of the kit. You can talk to your veterinarian about kit options and there are many reviews online to help choose the best kit for you and your dog.
