Why Chicken Hearts Are One of the Best Natural Sources
If you've been reading about dog nutrition over the last few years, you've probably come across the word taurine.
Veterinarians and researchers have been talking about taurine because it plays an important role in a dog's overall health—especially heart health.
So what exactly is taurine? Why is it important? And which foods naturally contain it?
Let's take a closer look.
What Is Taurine?
Taurine is an amino acid that helps support several important functions in your dog's body, including:
-
Normal heart function
-
Healthy eyes and vision
-
Muscle function
-
Nervous system function
Most healthy dogs naturally produce the taurine they need when they're eating a complete and balanced diet. However, some dogs may have lower taurine levels because of genetics, certain health conditions, or dietary factors.
Why Did Taurine Become Such a Big Topic?
Taurine became front-page news in the veterinary world several years ago when researchers began investigating a possible connection between certain diets, low taurine levels, and dilated cardiomyopathy (DCM)—a serious disease that weakens the heart muscle.
Golden Retrievers received particular attention because veterinarians began seeing an unexpected number of cases involving taurine deficiency. That research led to additional studies involving many breeds and helped increase awareness about the importance of balanced nutrition.
If you'd like to learn more about the research, these are two excellent resources:
Why Are Chicken Hearts Such a Great Source of Taurine?

Because they're packed with nutrition and have a strong aroma that dogs love, chicken hearts have become a favorite among trainers looking for high-value rewards.

Should Dogs Take Taurine Supplements?
For most healthy dogs, no.
Dogs eating a complete and balanced diet generally produce the taurine they need naturally.
If your veterinarian suspects a taurine deficiency or another medical condition, they may recommend blood testing, dietary changes, or supplementation based on your dog's individual needs. Never begin supplementation without consulting your veterinarian.
