Confirming
By a Pom's behavior (nesting, mood changes), slight popping of nipples and a firmer stomach, you will start to have suspicions by Week Two. 15 to 30 days after conception, her stomach will be visibly swollen enough for you to know that she is carrying pups.
There are 4 methods for confirming that a dog is pregnant:
• A blood test that checks for a hormone called hormone called relaxin. This can be accurate as early as Day 22; however you may want to wait until Day 27 when results are more dependable.
• An ultrasound can confirm pregnancy as early as Day 28
• Palpation (the vet feels the abdomen) can also confirm pregnancy as early as Day 28
• An x-ray can confirm pregnancy as early as Day 42 it takes this long for bones to calcify enough to be shown), however it is suggested to wait until Day 55 for an accurate reading of how many puppies to expect.
