“The cases listed by the FDA are cases that are confirmed.”
In the FDA report released on June 27th, 2019, all cases that had a diagnosis of DCM were released to the public. Here it is quoted from their article: “Brands that were named ten or more times are featured below. For a granular, case-by-case breakdown of DCM reports submitted to the FDA, see Canine Dilated Cardiomyopathy Complaints Submitted to FDA-CVM Through April 30, 2019 .”
Here are some example as to some of the descriptions submitted to the FDA in the case report.
“DCM and CHF Taurine not measured .”
This provides no helpful information and could easily have just been the veterinarian’s opinion since there is no evidence of tests that were done.
“(b)(6) (half sister; (b)(6) - (ICSR) of 2063133) diagnosed with DCM and CHF so screened by RDVM for BNP which was elevated. Evaluated at (b)(6) 2/1/19. ARVC/diet-induced DCM with ventricular arrhythmia. Diet changed to Royal Canin Early Cardiac and will re-evaluate in 3 months I have diet sample. 3 other dogs in household (1 had normal BNP, other 2 not yet evaluated) .”
This case jumps to the conclusion that it is diet-induced DCM even though it states that there is a genetic link to another dog that was reported to have DCM and the results of changing the diet were not reported.
As you can see these are not confirmed cases of diet-induced DCM. The FDA picked out 13 cases to do necropsies on, and only 10 of them actually had DCM . That gives these reports a 23% inaccuracy. You must also consider that these are most likely 13 of the most conclusive, well-documented cases. If you extrapolate the 23% misdiagnosis found in the necropsies, then 121 dogs of the 524 pets would have been misdiagnosed. That’s 121 dogs that could have potentially been treated for the disease they actually have, and this is what is troubling. In addition, only 41.7% of the blood tests submitted had low taurine.
All that the FDA requires is a diagnosis from a veterinarian or a veterinary cardiologist to be a “case.” “For the purposes of this investigation, the FDA defines a “case” as an illness reported to FDA involving a dog or cat that includes a diagnosis of DCM. … The numbers below only include reports in which the dog or cat was diagnosed with DCM by a veterinarian and/or veterinary cardiologist .” This does not say anything about the diet, or that DCM was confirmed, just diagnosed.
“Every test on these foods has shown them to be safe, you are correct. "Tests on the foods", not on what happens when the dogs' ingest the foods. Just because a food is nutritionally balanced on paper, does not mean the nutrients are bioavailable to the dogs' body.”
“The FDA did not say low taurine was the only cause of dietary DCM. They stated half of the dogs had normal taurine levels. It doesn't matter how much taurine is in the food, as a matter of fact, as you well know, dogs do not need taurine added to their food. They can synthesize their own taurine from the amino acids cysteine and methionine. Dogs need nutrients, not ingredients. Ingredients are simply the vehicles that deliver nutrients. The fact ingredients are balanced on paper, does not mean the nutrients are bioavailable to the dogs body when they are ingested. It is why board-certified veterinary nutritionists or PhD small animal nutrtionists should be formulating diets.”
132 of the cases reported to the FDA contained blood and/or plasma taurine tests . Combining this with a test of the food will give you the ratio absorbed (bioavailability). You can also do this with any other nutrients of concern.
“if there is no problem, can you tell me why these foods that are "safe", are suddenly adding taurine to their diets?”
“By the way, I wonder why Diamond Foods suddenly is advertising to hire a Vet Cardiologist, as are some other companies having a hiring frenzy?”
We can only speculate on questions like this as there’s no proof as to the mindset of the decision makers. My personal thought is that misinformation spreads fast, so it’s easiest for them to spend the couple cents to add taurine to the bag and appease as many customers as possible. There is no harm in adding the taurine, so for them it is a minor cost to appease their clientele even if it is not necessary.
“Can you cite scientific research these companies have published on why it was a good idea to almost double the fiber in some of their formulas? Or why it seemed to happen after Canada, years ago, sold their glut of peas to U.S. dog food manufacturers?”
I am not sure how to answer this because I’m not sure where you are getting your “double the fibre” information. Most of these foods contain between 4-6% fibre, which is the same as the foods with grains. For example, some grain free foods on the list: Acana Pacifica Dog has 6% fibre, Taste of the Wild Sierra Mountain has 5%, Fromm Chicken Au Fromage has 6.5%. Compare that to some foods with grains: Fromm Chicken A La Veg has 5.5% fibre, Acana Wild Coast has 5%, and Hill’s Prescription Dental Care has 10% fibre. As you can see, this statement does not appear to be true. I also don’t understand what is wrong with Canada selling its products to the USA. I personally like to support our Canadian growers. I much prefer this to these companies buying from China.
“While doing your research, please research the difference between DCM and dietary DCM. DCM cannot reverse itself...ever! It can only be managed with meds. It never goes away.” “Dietary DCM exists because it is being reversed. There are many, many decades of research in genetic DCM and other forms. Please show me the research stating genetic DCM can be reversed. There are none because it can't. As a former (human) cardiology tech, I can tell you it isn't reversed in humans either.”
“Heart conditions not due to food cannot be reversed with or without (diet change) meds. I made a rather good living out of college (University of Maryland Hospital) working in the cardiology field.”
“I know the other reasons and there are many. However, DCM caused by flea meds, heartworm meds, infections, genetics, is not going to be reversed by a diet change.”
“We are not talking about DCM caused by other factors as you have listed many you believe contribute. We are talking about dietary DCM. DCM that is reversed by, in some cases, by diet change ALONE. You have not replied to how that can possibly happen.”
This is simply incorrect. Dietary DCM as of yet has no confirmed mode of action, only theories relating to taurine and phytic acid. This means it is impossible to compare the differences between it and other causes of DCM. As stated by Dr. Weigner (MD, FACC) and Dr. Morgan (MD, PhD), “Dilated cardiomyopathy (DCM) can be caused by a variety of disorders. In more than 50 percent of cases, however, no cause can be found, and the cardiomyopathy is called "idiopathic." Some causes of DCM are reversible and the condition improves once the cause is treated or eliminated or the condition subsides. Other causes of DCM produce irreversible damage .” In a paper called Cardiogenetics, Quarta et al. stated in their paper “Dilated cardiomyopathy (DCM) is a genetic or acquired heart muscle disorder characterized by dilation and impaired contraction of one or both ventricles. In the acquired forms of the disease, if the pathogenic agent is persistent, undiagnosed or untreated, permanent ultrastructural and morphological changes may lead to irreversible dysfunction. Conversely, when DCM is promptly recognized and treated, the heart may show an extraordinary ability to recover from left ventricular(LV) systolic dysfunction .” In a study by Khochtali et al., they reported reversing DCM with hormone therapy caused by hypothyroidism and concluded that DCM cases should make sure to test thyroid function in order to rule out hypothyroidism as a cause . DCM is also talked about in a book titled Laboratory Diagnosis of Viral Infections, in which they talk about how DCM caused by viral infections can be reversed depending on the severity of the infection .
“It is NOT ingredients, it is about formulation. Please tell me what doubling the amount of fiber in dog food does to bioavailability?”
As we stated earlier, not really sure where the “doubling fibre” claim comes from. Please refer to our example above. In addition, a formulation is a combination of ingredients, especially since the list from the FDA contains brands with a wide range of meat to peas/lentils/potatoes ratios. Also, some of the brands mentioned have foods where the peas and lentils don’t come up until the twentieth ingredient with percentages listed on the ingredients, so the argument of there being too much of them in the formulation is false.
“Some of these companies list a meat source and then the next 8 ingredients include, green peas, yellow peas, chickpeas, potatoes, garbanzo beans, red lentils. Their is no scientfic research on that much fiber in dog food.”
“Corn does not usually show up in an ingredients list a half dozen times under different names (yellow corn, white corn, red corn, etc.).”

We do not recommend all these brands but are trying to point out that there is a vast difference in quality across grain free foods. We are not saying they are all good, but if you are making the point that all grain free foods are primarily peas and lentils it must be consistent across all of them. Otherwise it’s just a basic nutritional argument about food quality that has nothing to do with grains or not.

The argument that if you combine all of the different forms of lentils they would be higher up in the ingredients list doesn’t equate to the same as foods that already have corn and wheat as the first ingredient. This is because one is a hypothetical and one is definitive. Also, you can see that many of these foods ingredient split as well across either multiple grains or multiple forms of the same grain.
“Look up the affects of lectins and phytic acid (phytate) on vitamins and nutrients in the body. Research a daily legume, lentil, tuber, diet on a body.”
We agree that they should not have a high phytic acid diet. However, here are the phytic acid levels of different ingredients: Corn 0.7-2.2%, Lentils 0.3-1.5%, Peas 0.2-1.2%, Rice 0.1-1.1%, Wheat 0.4-1.4%, Soybeans 1-2.2% . Those are all in dry matter. That means if you were to apply them to a wet ingredient you would have to factor in moisture content. As you can see by these numbers, two different foods, one with corn and one with the same amount in lentils and peas, the one with corn would be higher in phytic acid. If the food has corn as the first ingredient it will be exponentially higher in phytic acid than a food with peas and lentils as mid to late ingredients.
“I think Dr. Greg Aldrich, PhD, president of Pet Food Ingredient and Technology Inc., and research professor and pet food coordinator at Kansas State said it best. "Some of the novel ingredients in diets involved and lack of publicly available research on their use in pets, compared to the relatively much larger amount of research in corn, wheat and soy (50 years of research) has given formulators a lot of understanding about them." His best line was, "marketing has outpaced science."”
People and animals have been eating and digesting meat for tens of thousands of years. There are many studies into how meat is digested and the nutrient content of meats. Most people eat meat every day, it is a major staple of our diet.
“I understand not every company has the money to hire over 500 full time scientists like Purina. Or not every company, like Royal Canin, can spend more money than any other company in research. They can't afford feeding trials that last longer than a year like big companies, they are expensive. But, some of these companies do not have "one" qualified person, not one.”
“Formulate with non-qualifed formulators. Chemical engineers, industrial engineers, degrees in equine nutrition and the list goes on and on?”
“Their company should have been placing our dogs before marketing and $$$$ and been using qualified formulators and doing research!”
I’m not sure where to start here… saying that these companies don’t have qualified employees is irrational. I’m not saying every single pet food company has the best and brightest, but clearly you can’t accuse every food of being made up entirely of unqualified people. Manufacturers employ full-time nutritionists . As for marketing dollars, the therapeutic diets spend the most money on marketing by sponsoring the veterinary colleges. Some of the foods listed do extensive marketing, but many of them do little to none.
“I have two friends that own two different independent stores in my town. We don't talk about it anymore because they are in total denial, even though I bought my dog's food from them. I'm mad for them also. They got sucked down the same rabbit hole we all did and went all in on BEG diets. What are they supposed to do? This is their livelihood?”
Don’t be fooled. A pet food store can easily change their grain free products over to those with grains. In many cases the foods containing grains would even buy out the grain free foods from the store, making it cost them nothing. It would literally be easier for a store to lean into the DCM scare. You should commend your friends for standing up for what they believe is right rather than condemning them thinking they are just trying to make money.
“More importantly, [corn] contains cysteine and methionine the two amino acids needed for dogs to synthesize their own taurine.”
“Peas are deficient in methionine so why add so many in the bag? There is a huge difference.”
This is getting back to the issue of taurine. Here are some cysteine (Cys) and methionine (Met) levels in various ingredients m(g/100g):
Corn: Cys 26, Met 67 
Peas: Cys 32, Met 82 
Lentils: Cys 118, Met 77 
Ground Chicken: Cys 188, Met 446 
Ground Turkey: Cys 179, Met 500 
Ground Lamb: Cys 198, Met 425 
“Taurine should not have to be added to dog food. It's added to cat food because they can't synthesize taurine.”
Yes, this we can agree with. As you can see above, as long as there is enough meat in the food, and the pet does not have a condition that prevents them from absorbing or synthesizing taurine from cysteine and methionine, then they should not need added taurine.
“I didn't come up with these ridiculous degrees formulating, the companies formulating did. I suggested the other day you start calling them. Have you made any calls? A master's degree is not qualified to formulate food. Someone that goes to Veterinary school and has 8 years of education, needs another 3 to 4 years to become a Veterinary Nutritionist. That's six more years of education compared to a masters degree.”
“Facts to me are what gets reported by scientists that have a much higher pay grade than I ever had, especially when those scientists are published and respected in their field. Facts are peer-reviewed published research. Facts are the FDA releasing the names of confirmed cases, not the unconfirmed cases.”
A thing that is known or proved to be true .
“For those of you worrying about the companies contributing to research through Universities and WSAVA, please contact your company and ask them why they are not contributing.”
That’s like asking why a family owned company doesn’t come in and spend as much as Tylenol. These pet food companies would have to spend the billions that Royal Canin, Hills, and Purina does in order o get their voice heard. If they did that then they would have to increase their cost because they would be taking money away from ingredient quality. Some of these companies do spend a lot of money on their advertising, but not all of them.
“the large pet food companies that so far appear to not cause increased risk of DCM, have spent decades with nutritional specialists researching balanced diets. I'm afraid they have my confidence, Julia with a biology degree does not.”
In fact, these therapeutic diets are not all balanced and do not all meet the minimum requirements of AAFCO. “Another concern with making therapeutic diets freely available to the public is that some do not meet the recommended nutrient standards for healthy pets. Depending on the disease they are designed to manage, they may contain unusually high or unusually low levels of protein, amino acids, sodium, or other nutrients .” Let’s take a quick look at a couple of pet foods.
Orijen Original: Fresh chicken meat (13%), fresh turkey meat (7%), fresh cage-free eggs (7%), fresh chicken liver (6%), fresh whole herring (6%), fresh whole flounder (5%), fresh turkey liver (5%), fresh chicken necks (4%), fresh chicken heart (4%), fresh turkey heart (4%), chicken (dehydrated, 4%), turkey (dehydrated, 4%), whole mackerel (dehydrated, 4%), whole sardine (dehydrated, 4%), whole herring (dehydrated, 4%), whole red lentils, whole green lentils, whole green peas, lentil fibre, whole chickpeas, whole yellow peas, whole pinto beans, whole navy beans, herring oil (1%), chicken fat (1%), chicken cartilage (1%), chicken liver (freeze-dried), turkey liver (freeze-dried), fresh whole pumpkin, fresh whole butternut squash, fresh whole zucchini, fresh whole parsnips, fresh carrots, fresh whole Red Delicious apples, fresh whole Bartlett pears, fresh kale, fresh spinach, fresh beet greens, fresh turnip greens, brown kelp, whole cranberries, whole blueberries, whole Saskatoon berries, chicory root, turmeric root, milk thistle, burdock root, lavender, marshmallow root, rosehips, enterococcus faecium. ADDITIVES (per kg): Nutritional additives: Zinc chelate: 100 mg
Hill’s Prescription Weight Management: Whole Grain Wheat, Whole Grain Corn, Powdered Cellulose, Chicken Meal, Corn Gluten Meal, Whole Grain Sorghum, Soybean Mill Run, Chicken Liver Flavor, Pork Fat, Soybean Oil, Pork Liver Flavor, Lactic Acid, Caramel color, Potassium Chloride, Choline Chloride, L-Lysine, vitamins (Vitamin E Supplement, L-Ascorbyl-2-Polyphosphate (source of Vitamin C), Niacin Supplement, Thiamine Mononitrate, Calcium Pantothenate, Pyridoxine Hydrochloride, Vitamin A Supplement, Vitamin B12 Supplement, Riboflavin Supplement, Biotin, Folic Acid, Vitamin D3 Supplement), Iodized Salt, minerals (Ferrous Sulfate, Zinc Oxide, Copper Sulfate, Manganous Oxide, Calcium Iodate, Sodium Selenite), Taurine, L-Carnitine, Calcium Sulfate, DL-Methionine, L-Threonine, L-Tryptophan, Mixed Tocopherols for freshness, Natural Flavors, Beta-Carotene
The recommended feeding guide for a 60lbs dog on Orijen is about 2 cups, while the Hill’s Prescription food is 5.5 cups of food. Note that the Orijen is so nutrient dense compared to Hill’s that you feed nearly 1/3 the amount to get the same amount of nutrients as dictated by AAFCO.
“I'm not even getting into the topic of the urban legend that is "grain-free". A myth that consumers bought into, and many dog food companies happily reaped the rewards.”
I’m not really sure how to answer this. Grain free foods aren’t a myth, roughly 30% of pet foods are grain free. If you’re talking about why they’re grain free the main reason is because of a scare in 2007 when wheat from China was infected with melamine and killed approximately 8500 pets. In an overcorrection people just decided to avoid all grains. I don’t believe grains are bad in general, only the ones with low nutrient density, the main culprits of allergies, or foods that use them in excess.
“some of those foods do contain prescription medications. The prescription food that I feed has tryptophan in it. In Canada, that is a prescription only medication (for humans too!), that treats mood disorders.”
This one isn’t all that relevant to DCM in particular. However, I did want to mention that, no, therapeutic diets do not contain prescription medications. They are “prescription” because some of them don’t meet AAFCO guidelines, and therefore are not supposed to be fed long term. Tryptophan is an essential amino acid found in meet and is especially high in turkey, the one that makes you sleepy.
“Just like human doctors doing research are sponsored by drug companies, animal doctors studies are sponsored by Dog Food companies. Therefore these studies are often biased.”
Yes, this is why it’s very hard to assess reports from vets about DCM and why we typically refer to human cardiology research as they aren’t influenced by any pet food companies. They would have no bias as far as grain versus grain free pet foods goes, and much of the research predates this argument.
“I had my dogs on one type of food and was told it was really bad for them so I switched and one of them got diabetes from eating the prescription food, because it was full of complex carbohydrates. In other words soya, corn and wheat.”
Diabetes is directly linked to causing cardiomyopathy . Hill’s Prescription Multi-Benefit w/d, which is recommended for use with diabetic pets, is 45% carbohydrates, 16% of which is fibre. That means 29% of it is starch and sugars. Orijen Original is 19% carbohyrates, with 5% being from fibre. That means there is twice as much starch and sugar in the Hill’s food than Orijen. Also consider that Hill’s recommends feeding 430g of food to a 60lbs dog, and Orijen recommends feeding 240g to a 66lbs dog. Therefore, a 60lbs dog on Hill’s is getting 125g of starch and sugar, whereas on Orijen they would be getting only 34g of starch and sugar.
“Larger companies also do research for bioavailability and digestibilty. Using Royal Canin as an example, this is what RC does beyond AAFCO trials. They do palability trials, digestibillity trials, blood parameters, relative supersaturation trials, stool confirmation, amino acid anaylsis, fatty acid analysis, toxicology and stability studies, clinical trials for efficacy in conjunction with veterinarians and pet owners. They also have peer-review research published. They can have 800 dogs in trials at any one time. Do you realize some of these companies do none of these things? Zero.”
There is no basis to say that other companies do not do this kind of testing. It is an accusation with no evidence. We have personally received blood tests from companies in the past and all of these tests are readily available from third party testing facilities, which offer a more reliable outcome since they aren’t employees of the company.
“You said the FDA is looking into genetics. Could you explain to me how Golden Retrievers, not prone to genetic DCM, suddenly a few years ago became prone overnight? Or why the University of Illinois is now studying cases being diagnosed in small dogs (Pomeranians, Boston Terriers and Schnauzers), also not predisposed to genetic DCM?”
No, we cannot, because that is why it is being research. However, the way genetics and breeding works is that even if one dog has a genetic predisposition for DCM it can be passed on very quickly. One male dog could have hundreds of offspring in its lifetime, and those puppies could have exponentially more. It is something that required sufficient research to assess.
“I'm so glad you brought up lamb and rice. An issue that occurred years ago when formulating with lamb. Lamb is a lower taurine meat, therefore harder to formulate. Companies doing research are now formulating successfully with lamb.”
What basis is there that every company that makes a lamb and rice formula is formulating a more balanced pet food then every brand that makes grain free food? Here is an example of a Purina food with grains, lamb, and no added taurine, methionine, or cysteine, or anything that would contain high levels of them:
Purina ONE® SmartBlend® Lamb & Rice: Lamb (source of glucosamine), rice flour, whole grain corn, whole grain wheat, chicken by-product meal (source of glucosamine), corn gluten meal, soybean meal, beef fat naturally preserved with mixed-tocopherols, mono and dicalcium phosphate, glycerin, calcium carbonate, liver flavour, salt, caramel colour, potassium chloride, dried carrots, dried peas, Vitamins [Vitamin E supplement, niacin (Vitamin B-3), Vitamin A supplement, calcium pantothenate (Vitamin B-5), thiamine mononitrate (Vitamin B-1), Vitamin B-12 supplement, riboflavin supplement (Vitamin B-2), pyridoxine hydrochloride (Vitamin B-6), folic acid (Vitamin B-9), menadione sodium bisulfite complex (Vitamin K), Vitamin D-3 supplement, biotin (Vitamin B-7)], Minerals [zinc sulphate, ferrous sulphate, manganese sulphate, copper sulphate, calcium iodate, sodium selenite], choline chloride, L-lysine monohydrochloride, sulphur.
There’s nothing to insinuate that the formula has been changed to adapt to the studies proving a link between lamb and rice and DCM.
“Since you did bring up the subject, the FDA also did not say just grain free. They included exotic meat. While you do not consider kangaroo, rabbit, bison,venison, etc.exotic, those meats do not have decades of research behind them.”
