Why do vets not recommend grain free dog food

The Truth About Grain-Free Dog Food: Insights from a Nutrition Expert

The phrase grain-free has become one of the most confusing and debated in the world of dog food in recent years. It was and is often seen as a positive many nutritionists warn against high levels of grains in dog food.

However, in recent years, a growing concern has emerged regarding the potential connection between canine dilated cardiomyopathy (DCM) and dogs diets with grain-free foods framed by some as the problem.

As a result, pet parents, believing they are offering their furry companions the best nutrition, find themselves troubled by the notion that their diet could be linked to such a serious disease.

While DCM has various causes, including genetics, medications, and infections, its crucial to note theres no scientific evidence definitively linking grain-free or grain-inclusive diets to DCM.

This, however, has not eased the concern or confusion among many pet parents. Not least because people confuse food advertised as grain-free which often has grain substitutes with food that simply has no grains in it, such as raw dog food.To address the uncertainties around foods labelled grain-free, we spoke Dr. Richard Patton, a seasoned Ph.D. animal nutritionist with over 40 years of experience and expertise in formulating canine diets, more than 25 scientific publications to his name, and who has authored a book on pet nutrition. Hes a nutritional consultant for the raw food community.

(Please note that these are Dr. Pattons expert opinions, not those of Dog Food Advisor.)

In the popular language of the pet food industry, grain-free trade signifies the absence of ingredients like corn, oats, wheat, soybeans, and the like. This labelling suggests the replacement of these perceived problematic grains with supposedly more benign options such as potatoes, sweet potatoes, or other non-grain alternatives.

However, the crux of the issue isnt the specific grains name but rather the quantity of soluble carbohydrates it contains essentially, starch and sugar. Potatoes, often deemed virtuous replacements for grains, can be just as carbohydrate-rich and, therefore, pose similar concerns as grains like corn. Similarly, a diet featuring lower levels of soluble carbohydrates can still be highly nutritious, even if it includes moderate amounts of grains.

How do I know if my dog should be grain-free?

Your dog should generally be fed a diet that is low in starch and sugar. Their diet should be low in soluble carbohydrates its usually easiest to feed your dog complete and balanced meat-based dog food.

Apart from honey, there are very few natural sources of food that are high in carbohydrates. If we were to survive in the wild, we would find many things to eat, but very few carbohydrates. Mankind made them easy to find, but a high-carb diet is ill-suited for our genetic machinery.

Should pet parents avoid grain-free food?

The thing to avoid is a high-carb diet. The pet food industry is dominated by brands that make crunchy kibble on a machine called an extruder. To properly run an extruder requires a fair measure of starch due to its inherent qualities. It expands when heated with water; it stays expanded when cooled and dried.

The pet food industry is a behemoth, with a dog or cat for every other person in the country. Big kibble has coerced the market into thinking kibble is the way to go. In fact, a pet parents buying decision is guided by three things: cost, convenience, and correct nutrition. Its hard to have all three. Big kibble trades on its strength in cost and convenience.

Are there different types of grain-free dog food?

There are different ingredients one can replace corn, oats, wheat, etc. with. However, if its a crunchy kibble, it will contain excess carbohydrates.

What are the benefits of grain-free dog food?

Given that both with grain and grain-free can be equally dubious due to high starch content, the benefits are confined to economics and convenience.

What are the disadvantages of grain-free dog food?

A grain-free kibble will be high in starch and deliver excess carbohydrates, the same as regular grain kibble. Everyone thinks fat causes obesity. This is incorrect. Excess carbohydrates cause obesity.

Does grain-free dog food cause heart disease (DCM, enlarged heart or dilated cardiomyopathy)?

There is no credible scientific evidence for this, let alone proof. If there is a link between diet and DCM in dogs, it is far more likely to be a matter of protein quality, amount and specific amino acid amount.

Is grain good for dogs?

Grain can be fed to dogs if fed in moderation. A primordial diet is 5-7% carbohydrate, and this is the dietary level mammals are genetically evolved to consume, and thrive on best.

Is grain-free food the same as gluten-free/wheat-free dog food?

If grain-free means the diet is free of wheat, rye, barley and oats, then the diet can be considered gluten-free. There are pet food kibbles in the market that snub these specific cereal grains.

If you or your pet has a gluten intolerance, you readily grasp the relevance of this issue. Gluten intolerance is a genetic inability to digest the gliadin fraction of the wheat protein gluten. Gluten is also found in the protein of rye and to a smaller extent in barley and oats. So no, grain-free does not speak to gluten-free specifically, but often a grain-free diet can be gluten-free as well.

Can puppies eat grain-free food?

Talking about grain-free dry kibble, yes, of course, they can eat it, and given that puppies chew on anything, they will appear to relish it. The excess carbohydrates in some foods are just as bad for puppies as adults. Puppy food should derive its calories from protein and fat, not from carbohydrates.

What is the best grain-free dog food?

The question should be what is the best type of food? Regarding grain-free kibble, one can assume the various competing products all comply with AAFCOs recommended guidelines for nutrient content.

In this regard, it is not easy to identify one superior brand among dry kibbles. However, pending AAFCO changes will call for labels to state not just total calories but what percentage of these total calories derives from protein, fat and carbs. This will greatly inform pet parents buying decisions and advance awareness that low-carb diets are best.

For example, a grain-free dry kibble with 30% carbohydrate calories is better than one that is 40 or 50%. Under current label rules, this way of evaluating and ranking is not possible. When it does become the norm, it will show that natural and natural raw diets at 5-10% calories from carbohydrates are the best.

Is grain-free food better for allergies?

If a pet is indeed allergic to one of the grains shunned in grain-free formulas (viz., corn, oats, wheat, soy, barley, rice) a grain-free kibble could lessen symptoms. There was an all-meat-type pet food producer who guaranteed his meat-based product would clear any skin problem or your money back. In 30 years he never refunded a cent. Often, a dogs food sensitivity is not to a specific ingredient but to a diets overall carbohydrate analysis. Lowering starch and sugar in a diet often lessens allergic symptoms.

Guide to Grain-Free Dog Food

Updated on January 4, 2020

Grain-free and gluten-free products have gained much popularity among people in recent years, and pet food manufacturers are following this trend, too. But is grain-free dog food the best choice for your dog?

What are the benefits of grain-free vs. grain dog food? Heres a guide to grain-free dog diets and how they compare to grain dog food.

What Is Grain-Free Dog Food?

Before we talk about grain-free dog food, you need to know which grains are commonly used in dog foods. These include:

• Wheat

• Corn

• Rice

• Oats

• Barley

• Rye

• Soy

Are Grain-Free Dog Diets Free of Carbohydrates?

While grain-free dog foods do not have grains, they do substitute other carbohydrate sources, such as potatoes, sweet potatoes, lentils, peas, or quinoa. Therefore, grain-free foods are not carb-free. In some cases, a grain-free food may be equal to or higher in carbs than dog foods with grains.

Is Grain-Free Dog Food Also Gluten-Free?

Grain-free and gluten-free are not synonymous terms.

Gluten-free foods do not have gluten-containing grains such as wheat, barley, and rye, but they may still contain other grains. And grain-free diets may be gluten-free unless they contain ingredients that are hidden sources of gluten.

In addition, studies have shown that commercial dog foods often have cross-contamination during the manufacturing process, and therefore, may not be totally free of the ingredients they claim.

Grain-Free vs. Grain Dog Food

Whole grains provide an important nutritional resource for your dog, including B vitamins, iron, magnesium, selenium, carbohydrates for energy, and fiber to aid in digestion.

You may have heard that grain-free dog food has more meat because it makes up for the lack of grains. Grain-free diets are not all meat, although they may have a higher proportion of meat in them. As weve learned, they also substitute some of those grains with other carbohydrates.

You may also think that grain-free dog diets include only high-quality ingredients, but this isnt necessarily true any more so than with grain dog food.

In certain situations, your veterinarian may recommend a grain-free diet instead of grain dog food. For example, in dogs suspected of having food allergies (also known as an adverse food reaction), a grain-free diet might be recommended on a trial basis to see if symptoms improve.

It is important to recognize, however, that very few dogs have allergies to the grains in dog foods. The vast majority of food allergies are to the protein source (meat) in the food.

Does Grain-Free Dog Food Cause Heart Disease?

There have been recent concerns regarding the safety of grain-free foods and heart disease in dogs. The Food and Drug Administration (FDA) has opened an investigation into the development of dilated cardiomyopathy in dogs that are fed grain-free diets.

Dilated cardiomyopathy is a heart condition resulting in an enlarged heart and thinning of the heart muscle. This weakens the heart and can lead to heart failure and death.

The FDA opened this investigation due to the rising incidence of dilated cardiomyopathy. They have found that with the 1100+ dogs studied, 90% of the products fed were labeled as grain-free diets.

The most recent update came from a virtual scientific forum where scientific experts from academia, industry, and veterinary medicine collaborated and discussed their research on DCM. Dr. Steven Solomon, Director of the Center for Veterinary Medicine (CVM) for the FDA, emphasized that this was not an investigative update, and stated the following in his opening remarks:

I believe that our approach to date speaks to the fact that, based off the adverse event reports we have received, we have observed an association between certain diets and DCM. However, it has been nothing that would trigger a recall or market withdrawal, because the DCM issue seems to involve more factors than the food itself.

In the ongoing investigation, he stated that the FDA hopes to:

...explore additional avenues about ingredient levels, nutrient bioavailability, ingredient sourcing, and diet processing to determine if there are any common factors. We have asked pet food manufacturers to share diet formulation information, which could substantially benefit our understanding of the role of diet.

His advice to pet parents was that the best thing that you can do is to talk to your veterinarian about your dogs dietary needs based on their health and medical history.

Should You Switch Your Dog to or From a Grain-Free Diet?

Your veterinarian should be consulted regarding the best dietary choices for your dog.

There have not been any recommendations issued by the FDA advising whether you should or should not feed your dog a grain-free diet, as their study is ongoing.

The most important consideration in choosing a dog food is that it provides complete and balanced nutrition.

If you are thinking of switching your dog to a grain-free diet, discuss the risks and benefits of feeding a grain-free diet with your veterinarian first.

If your dog is already on a grain-free diet, and you want to know if you should switch to a dog food that has grains, ask your veterinarian what the best dog food option would be for your particular dog.
