No Additional Trips to the Vet: Save Time and Money with at-Home Dog Pregnancy Tests for Dogs 

Our pregnancy test for dogs is fast, efficient, and easy to use. Most importantly, it can be used to test at home, freeing you to take your dog to the vet to test for pregnancy. This form of canine pregnancy testing measures a hormone in the blood known as relaxin, a hormone produced by the developing placenta and the ovaries of a female dog during pregnancy. Relaxin, as its name might suggest, relaxes the ligaments in the pelvis in order to prepare the female for labor. It is a reliable indicator of pregnancy.

Keep stress levels low on your dog, and save time and money by performing your own dog pregnancy tests at home with this special kit that will deliver you results in as few as 10 minutes. This extremely easy-to-use kit comes with blood-drawing needles, does not require refrigeration, and has a 12-month shelf life so you don’t need to use it immediately. These accurate tests can also detect whether or not a dog is pregnant by the 25th day after breeding - nearly as early as three weeks afterward.

Don’t “wait” for weight gain associated with developing puppies! Simpler and more affordable than an abdominal ultrasound and reliable, as results are easy to read. The clearer the line on the test, the higher the levels of relaxin in the blood. The test kit also comes with easy-to-use instructions for detecting pregnancy via a blood sample. 

How do these simple tests work?

The Relaxin test detects pregnancy as early as day 25 post-breeding! Very nice! Use just a few drops of serum. So Easy and Fast! 

Relaxin is a hormone produced only in pregnant females, which makes it an ideal pregnancy test! The more relaxin present in the serum sample, the clearer the line. 

Beat ultrasound diagnosis with this simpler, but effective and accurate test.

Excellent Customer Service

We recently found CanineP4 after a terrible experience with a Wondfo Rep in Florida.
We were worried about trusting another company but after speaking to them learned that they actually are very knowledgeable.
We will continue to purchase all of our Breeding & Repro Supplies from them.
Thank You CanineP4
