Is grain-free dog food bad? – American Kennel Club (2023)

It was a routine vet visit for Oliver, Julie Carter's three-and-a-half-year-old son.Golden Retriever. At least until the vet heard Oliver's heart and uttered the phrase that would change his life: "He has oneheart murmur.“

It was February 2018 and Carter also brought up an interesting article on the Morris Animal Foundation website noting a worrying increase in the number of Goldens diagnosedDilatative Kardiomyopathie (DCM). These dogs had two things in common: they were deficient in taurine, an amino acid, in their blood, and they were fed small-company dog ​​food, often with unusual ingredient lists, grain-free or high in legumes. Oliver ate this diet. He had low taurine levels. And he had DCM.

Oliver, who is now in the care of a veterinary cardiologist, was immediately placed on a grain-based diet and received taurine supplements and heart medication. He remained symptom-free until one day, without warning, he suffered a fatal arrhythmia while walking across the kitchen floor. It was August 2018, six months after her diagnosis and just five days after she celebrated her 4th birthday.

DCM is a serious heart muscle disease that can be fatal. Occurs more frequently inlarge breeds, and in some breeds it is thought to have a genetic component. It is also common in middle-aged to older dogs. Goldens are not generally considered a risk breed for DCM, but they are at risk of taurine deficiency.

taurine and heart disease

Taurine, an amino acid abundant in meat, has been linked to cases of feline TMD for the past 30 years. It turned out that commercial cat food did not contain enough taurine. When taurine was added to the diet, DCM in cats basically disappeared.

Taurine was immediately suspected in canine DCM, but relatively few cases of taurine-deficient DCM have been identified in dogs. However, certain diets, particularly those high in lamb, rice bran, or fiber (especially beet pulp) and very low-protein diets, have been linked to taurine deficiency in dogs.

Fast forward to 2018. Veterinary cardiologists have started noticing a higher than average number of dogs with TMD. At Tufts University, Lisa Freeman, DVM, Ph.D., DACVIM, a board-certified animal nutritionist specializing in research into the nutritional effects of heart disease, reported that an alarming number of these dogs ate what they BEG (boutique, exotic ingredients, or grain-free ).

Boutique diets are made by small businesses with no nutritional testing facilities. Diets with exotic ingredients use unusual sources like kangaroo or duck that have not been extensively tested, more common sources like chicken or beef. Grain-free diets replace grains like rice and corn with potatoes orLegumes (beans, peas and lentils)as a carbohydrate source. No study has ever shown that a grain-free diet is superior to a grain-containing diet.

The FDA gets involved

Freeman worked with several veterinary cardiologists and alerted the Food and Drug Administration (FDA). In July 2018, the FDA announced it had found enough evidence to investigate. In November 2018, Freeman and his collaborators published an op-ed in the Journal of the American Veterinary Medical Association. It would become one of the most downloaded articles in the history of this publication.

The FDA hassince the release of several updates. From January 2018 to April 2019, the FDA received reports of 553 dogs with DCM, ranging from zero to three dogs, compared to previous years. These included 95 Goldens, 62 Crossbreeds, 47 Labrador Retrievers, 25 Great Danes, and over 50 other breeds with more than one report.

The FDA report lists 16 dog food companies that have had 10 or more cases of DCM related to their food, but many other foods are implicated. The brands themselves are probably not the important part of the report, but what these foods have in common.

When examining the diet, no protein source stood out as being over-represented. In fact, the most common proteins were chicken, lamb, and fish, although some included uncommon proteins like kangaroo, bison, or duck. More than 90% of the diets were grain-free and 93% ofDiets included peas or lentils. A much smaller proportion contained potatoes. When these foods were tested, they contained, on average, the same percentages of protein, fat, taurine, and taurine precursors as grain-based products.

Joshua Stern, DVM, Ph.D., DACVIM, was one of the first veterinary cardiologists to notice the increase in DCM cases in golden retrievers. Since then, Stern of the University of California, Davis School of Veterinary Medicine, has been studying Goldens with DCM and taurine deficiency. In an unpublished study of 24 Goldens with confirmed DCM and low taurine, all but one dog showed significant cardiac improvement after changing their diet and adding extra taurine. All dogs were on a BEG diet at the time of DCM diagnosis.

And now?

Although many dogs eating a BEG diet do not appear to develop TMD, veterinary cardiologists recommend dog foods from established manufacturers. They conduct feeding tests and use standard ingredients like chicken, beef, rice, corn, and wheat. They point to five American manufacturers: Purina, Hills, Royal Canin, Iams and Eukanuba.

Critics claim that the number of dogs reported compared to the number eating these diets hardly represents an epidemic and that there are no controlled feeding trials comparing DCM rates on BEG and non-BEG diets. However, most cases of DCM are still unreported and smaller BEG companies do not carry out feeding tests.

At least one study is ongoing. Researchers at the University of Florida College of Veterinary Medicine have begun a study funded by the AKC Canine Health Foundation to determine if diet type affects echocardiographic, taurine, or blood biomarker levels in apparently healthy dogs. Dogs with abnormalities are given a change of diet and are then re-examined for a year. Two "endangered" breeds (Golden &Dobermann pinscher) and two “no risk” breeds (WhippetseMiniature Schnauzer) will participate.

"We are working hard to answer this question as quickly as possible," says lead researcher Darcy Adin, DVM, DACVIM. This study will not answer all questions, but is expected to address whether diet-associated DCM is real, if so, what types of foods are associated with it, whether taurine deficiency plays a role, whether cardiac biomarkers in the blood are useful can be used to identify and whether improvement can be observed after a nutritional intervention.

Meanwhile, dog owners remain concerned. Excellent resources are available thanks to dedicated vets and dedicated dog owners. Several Facebook pages are dedicated to the topic; The best known, Taurine Deficiency Dilated Cardiomyopathy (Nutritional), has over 100,000 members. Other groups include Taurine Deficiency in Golden Retrievers and the DCM Canine Nutritional Support Group, a support group dedicated to owners who have an affected dog or have lost their dog to DCM. There's one toowebsite.

Over a year after Oliver's death, Carter is dealing with his loss by helping others deal with their loss and by making the issue public. This has prompted many owners to have their dog's heart checked by a veterinary cardiologist.

But Oliver isn't her only concern. Riley, Carter's 9-year-old Golden, was diagnosed with the same condition. "Although their cases share several similarities, the most striking fact is that Oliver and Riley ate the exact same food for several years. ...a grain-free diet with limited ingredients that's enriched with legumes," says Carter. Carter also has "an adorable 1-year-old Golden named Finn who has never eaten a BEG diet and never will."

Oliver is arguably the best-known victim of DCM. "The decision to be proactive and educate others about this life-threatening disease was a quick and easy decision," Carter recalls. “When Oliver was diagnosed in February 2018, there was very little publicly available information about DCM in canine diets. Shortly after Oliver's diagnosis, I dubbed him the "face of dilated cardiomyopathy" in the hope that putting a face to this terrible disease would draw dog owners' attention and make it easier for them to shed light on it.

"While Oliver is often considered the face of DCM, he's not alone," says Carter. “There are hundreds of other dogs that are suffering and dying from this preventable disease. ... I've seen firsthand how many of these heartbroken families are collapsing under the emotional, physical and financial toll that comes with this diagnosis."
