What tests diagnose liver shunt in a tiny puppy? How long for results?

Updated On September 23rd, 2025

Pet's info: Dog | Pomeranian | Male | unneutered | 2 months and 27 days old | 1lb

My Pomeranian puppy is now 12 weeks old. He was born a week premature. He weighs 1 pound 7 oz. The vet believes due to his small size he may have a liver shunt so he's been monitoring him Although, he hasn't shown any signs of having it besides him being tiny . They want to hold him longer to make sure he doesn't have one. What tests should I make sure to ask the vet about to make sure he doesn't have one . Would also love to know how long it would take to find out results if he has one or not.

Congratulations on your new baby! He is adorable! The most common tests we start with to evaluate for liver shunts are baseline labwork (which includes a full chemistry, complete blood count and urinalysis) as well as a pre and post prandial bile acid profile. The bile acid profile is to specifically look at the liver function. Any of those tests results are available within a couple of days. Unfortunately, sometimes those test results are inconclusive, and we have to do additional testing. I have included a link below with more information about liver shunts. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=2533 Good luck! I hope that was helpful! Thanks for using PetCoach.
