Is A Grain Free Diet Really Bad For A Golden Retriever Heart?
Is A Grain Free Diet Really Bad For A Golden Retriever Heart? You adore your Golden Retriever and would give them the world you want the very best, which means feeding them in the right way. For the last couple of years, there has been growing concern regarding whether grain-free dog food is bad for Golden Retrievers, and the answer is quite complex, but there is now thought to be a connection which needs taking into account.
The Heart of the Matter: DCM and Golden Retrievers
DCM Dilated Cardiomyopathy: The condition associated with grain-free foods and heart conditions is called dilated cardiomyopathy (DCM). It is an often fatal disease of the heart muscle in which the heart enlarges and loses the ability to pump blood. Congestive heart failure is a possible outcome of DCM.
Although genetics can play a role in the development of DCM, especially in some giant and large dog breeds, a non-hereditary cause has been developed, which correlates strongly with certain dog foods. Golden Retrievers seem to be exceptionally susceptible to DCM along with Labrador Retrievers and Doberman Pinschers.

The FDA Investigation
The concern then burst into public focus in 2018 with the opening of an FDA investigation of the potential relationship between grain-free dog foods and DCM. Many of these foods tend to contain high amounts of legume-(like peas, lentils and chickpeas) and potato-based ingredients in place of grains.
What the FDA did not find: The probe, which concluded in December of 2022, did not prove a cause-and-effect relationship (in other words, it didn’t firmly establish these foods actually contribute to the onset of DCM). That is far from being a settled matter.
The Scientific Evidence: What Do Studies Show?
While a cause-and-effect has yet to be definitively established, the scientific literature now contains an expanding collection of peer-reviewed studies revealing these troubling patterns:
- Possible heart muscle damage: In 2021, a study published in the Journal of Veterinary Internal Medicine determined that healthy dogs on grain-free diets and/or diets containing FDA ingredients of concern showed increased blood levels of high-sensitivity cardiac troponin I (hs-cTnI), which may signal minimal damage to heart muscle cells.
- Metabolic disruption: In 2022, research in BMC Veterinary Research found that otherwise-healthy Labrador Retrievers placed on a legume-heavy, grain-free diet for just 30 days had markedly decreased red blood cell counts and increased levels of plasma phosphate characteristics similar to those found in dogs suspected of having DCM. This suggests rapid dietary influences can result in physiological changes.
- Taurine metabolism: Taurine is a vital nutrient for cardiac health.
- Despite findings: by some groups that taurine blood concentrations for dogs fed grain-free foods was neither deficient nor, in some cases, elevated, other researchers suggested there might be a less obvious problem related to body function uptake, use, or elimination of taurine. A study by 2022 found that in dogs eating a grain-free diet, the ratio of urinary taurine to urinary creatinine was significantly decreased (77-78%).
Why Golden Retrievers May Be at Higher Risk
The scientific community has known since the 1980s that low taurine levels can cause DCM in Dogs. This has given rise to the ‘taurine deficiency hypothesis’. According to this hypothesis, the components in a certain grain-free food have the ability to:- inhibit the dog’s capacity to take up taurine.- impair taurine synthesis within the dog from other amino acids. Goldens, are believed to be a breed at increased risk for taurine deficiency secondary to DCM due to the species specific synthesis pattern of taurine .

What This Means for You and Your Golden?
It’s certainly a bit of information that could be intimidating to the Golden Retriever owner. Here’s a view from a veterinary perspective: While it’s not a certainty, it’s real and frequent enough that it warrants attention. The FDA hasn’t banned grain-free food, but the signals are too strong to turn a blind eye to.
Frequently Asked Questions (FAQs)
Is it me, is my Golden’s grain-free diet to blame?
I admit, it did briefly enter my mind whether my Golden’s grain-free diet could be contributing to DCM risk. Not all grain-free diets are a problem. The biggest problem dog food is of concern currently are those labeled “BEG” or boutique exotic and grain-free diets high in potatoes and legumes.
Am I concerned about any ingredients that grain-free food includes?
Yes. Dogs should be weary of diets where ingredients such as peas, lentils, chickpeas, beans or potatoes make up the top 10 listed ingredients. These are added to enhance protein and carbohydrate content in grain-free diets.
Does the FDA acknowledge grain-free foods causing DCM?
Nope. The investigation found that there is an association between a portion of these diets and DCM, but there is no causal link proven, nor does the FDA mention there will be an update in the future. There have been no studies, reports or information that suggests these diets can cause DCM; therefore the investigation has since ended as of December 2022.
What is my Golden Retriever’s DCM risk?
They have a higher genetic predisposition to a taurine deficiency which plays a part in diet-related DCM.
Do you know the symptoms?
DCM in dogs usually develops very gradually and can be missed easily. Lethargy, loss of energy and desire to play, weak pulses, decreased heart rate, difficulty breathing, shallow and fast breathing, coughing (especially a dry cough), collapse and swelling in the abdomen (due to fluid accumulation). My Golden is diagnosed with a true grain allergy.
Is a grain inclusive diet a better option?
Veterinary cardiologists recommend that you stick with food containing grains and buying from a company that is reputable and conducted adequate feeding trials on their food. If your dog does have a true grain allergy that you and your veterinarian have verified, your vet can provide guidance on grain-free options that won’t be problematic.
Do I need to change her diet now?
Do not make abrupt changes to a diet, your veterinarian is the best person to talk to regarding what is recommended. Switching diet gradually will help to reduce stomach upset.
Is it the absence of grain, or the replacement of grain, causing the problem?
Many believe the issue lies with the ingredients substituted for grains namely the use of high proportions of legumes and potatoes which affect taurine and potentially other physiological processes.
How should I choose the right diet for my Golden?
Look for foods formulated by well-regarded companies with a proven history and following the World Small Animal Veterinary Association’s Global Nutrition Guidelines. Among these recommendations: The company employs a full-time qualified veterinary nutritionist, conducts feeding trials and follows strict quality controls. You and your veterinarian can decide what’s best.
Conclusion
As for the answer to whether grain-free is “really bad” for a Golden Retriever’s heart…it’s not quite so straightforward as just yes or no. We cannot scientifically declare every grain-free diet bad. Yet, we have clear, evidence-based reasons to be wary. A breed predisposition plus concerning biomarkers and altered metabolism in combination equal risk. For your treasured Golden, you will do best if you base decisions on solid science and a discussion with your veterinarian.
