Everyone wants what’s best for their dog. We consider them to be part of our families, after all. So it makes sense that you want to feed your dog the most nutritious diet possible.

In recent years, tons of grain free dog food products have hit the market as brands seek to capitalize on health-conscious pet owners.

But is a grain free diet really the best choice for your dog? The FDA says it could do more damage than good – but not 100% of the time.

It’s important to educate yourself about the diet your dog really needs so you can keep him healthy for many years to come.

Grain Free Dog Food And Heart Disease

In July of 2018, the Food and Drug Administration (FDA) put out a warning for all dog owners about grain free dog food and heart disease – or rather heart failure.

According to the FDA, they noticed an uncomfortable link between grain free diets and a somewhat rare condition called dilated cardiomyopathy (DCM).

Deputy Director of the FDA’s Center for Veterinary Medicine’s Office of Surveillance and Compliance, Martine Hartogensis, D.V.M., said that this occurrence was particularly unusual because DCM started appearing in dogs who weren’t genetically prone to the condition.

If the dogs weren’t prone to the condition, that means something in their environment is likely triggering the condition. The FDA dug a little deeper and noticed that these dogs seemed to have something in common: peas, lentils, legumes, and potatoes made up the bulk of their diets.

In other words, certain types of grain free dog food are weakening and enlarging heart muscles in dogs leading to congestive heart failure. It’s unclear if consuming lentils and legumes contributes to DCM or if a doggy diet lacking whole grains is the culprit.

The FDA said that the dogs with DCM had particularly low levels of the amino acid taurine which is found in meat and dairy like dark meat chicken, eggs, beef. Ironically enough, the FDA also said that legumes, peas, and lentils constituted a large portion of these dogs’ diets which likely means their grain free food contained more of these ingredients than meat.


What Can You Do To Protect Your Dog From Grain Free Dog Food And Heart Disease?

If your dog has an allergy or you’re dead-set on a grain free diet, there are a few steps you can take to make sure your dog stays safe and healthy.

  • Predisposition: Large breeds like Boxers, Great Danes, and Saint Bernards are naturally at risk for DCM. The condition does not often occur in small and medium breeds with the exception of Cocker Spaniels. Avoid a grain-free diet if your dog falls into one of these categories.
  • Read Ingredients: Don’t rely on lentils, peas, chickpeas, beans, or potatoes as a protein source for your dog because they don’t contain much taurine. If you want to feed him a grain free diet, look for foods with chicken or beef as the first ingredient so your dog receives adequate levels of taurine. Lamb is a bad source of taurine as well.
  • Mind Your Dog’s Macros: A high-fiber diet can negatively affect taurine absorption. Keep this in mind.

Keep in mind that a lot of grain free varieties contain exotic meats like kangaroo, bison, lamb, or venison. Stick with proteins that you know contain good taurine levels like chicken and beef. Exotic meats are okay occasionally, but they shouldn’t make up the bulk of your dog’s diet.

In some cases, DCM occurred in dogs without low taurine levels so we can’t be sure what’s behind the grain free DCM epidemic just yet.

What Does Your Dog Need In His Diet?

We know taurine is important for heart health but what else does he need to ward off aging and illness?

Dogs are mammals and require a lot of the same nutrients people need to stay healthy. Unlike cats, dogs are not strict carnivores: they can (and should) consume a balanced diet of fruits, veggies, grains, and carbohydrates as well as meat.

At the same time, dogs are a little different than humans so his diet shouldn’t be identical to yours. So, what’s the best diet for your dog?

It depends.

You should take a few things into consideration when choosing a diet for your dog such as his size, breed, and age. Talk to his vet about choosing the right type of food for your dog’s life stage, size, and breed.

You should only seek a grain free diet for your dog if your vet informs you of a food allergy to gains (which is very uncommon). Grain free foods and legumes probably aren’t dangerous in moderation, but treat them as a special meal rather than diet staples.

“Complete And Balanced”

Most standard and grain free dog food brands contain a label that says “complete and balanced.” This isn’t just some hip marketing lingo that doesn't carry weight like “healthy” – it actually means the food you’re about to purchase for your dog is complete and balanced.

This term means that the food contains “complete” nutrition from protein, fat, and carbohydrates in a “balanced” ratio. It’s really that simple. You just need to figure out what “complete and balanced” means for your particular pooch. Your vet can help.

How We Chose Our Rankings

We wanted to make sure your dog will get adequate levels of taurine. Although some dogs with normal levels of taurine in their system still came down with DCM, many of the dogs suffering DCM had very low levels of taurine.

We tried to find grain free dog food products that contained meats with high levels of taurine like chicken and beef. These are the varieties that won a five-star rating.

Four-star rankings might have legumes or peas. Feed these to your dog in moderation to avoid lowering your dog’s taurine count to dangerous levels – and always check with a vet.

Our three-star rankings don’t contain taurine-rich proteins like beef, turkey, or chicken. These rely on other sources of protein like salmon or exotic meats. You should treat these foods as a special occasion food and talk to your vet about proper diet.

Your Guide To Choosing The Best Grain Free Dog Food

You want to feed your dog the most nutritious food possible, right? Well, in order to do that you need to do some research. The truth is, a grain free diet might not be the best choice for your dog, in fact, it could possibly do more harm than good.

Here’s some tips for making the most educated decision possible.

Understand Wording

Dog food brands like to use a lot of buzzwords to make their food sound healthier than it really is. Sometimes it seems like a constant game of cat and mouse as consumers try to figure out the tricky terms and companies switch up their tactics.

Look at the product names – they can tell you quite a bit.

In terms of meat, anything listed as “beef” or “chicken” in the product name must contain at least 70% of that meat. If you see the term “chicken platter” or “beef dinner,” this means that the protein constitutes just 25% of that food.

If you find anything that says “with chicken” or the like, this indicates that only 3% of the product contains that meat. Avoid anything that says beef or chicken “flavor” or lists ambiguous “meat” as an ingredient.

Moderation Is Key

It may not be safe to feed your dog an entirely grain free diet unless your vet tells you he has an allergy. In the cases of dogs with DCM, these pups were relying on legumes, peas, potatoes, or lentils for the bulk of their diet.

This certainly doesn’t mean that your dog should avoid grain free dog food at all costs but rather that these ingredients should not be diet staples – especially above animal protein sources.

Consider A Supplement

If a grain free diet is an absolute must for your dog, consider adding a reputable supplement to his diet to ensure he’s getting all of the proper nutrients.

Talk to your vet about the consequences of a grain free diet in dogs and what you can do to minimize the risks with supplements. Your doctor can also give you suggestions on supplement brands.

Remember That Your Dog’s Health Comes First

Boutique foods and diets are certainly tempting – especially if you stick to a certain diet yourself – but they may not give your dogs and cats the nutrition they need.

Cats, for instance, should absolutely never be fed a vegan (or even vegetarian) diet. Their bodies just can’t handle it.

Likewise, dogs’ bodies require a certain diet to function properly. Stick with reputable brands and traditional meat ingredients for the bulk of your dog’s diet. Exotic ingredients and legumes are okay every once in a while, but you should not rely on them as a base for your dog’s nutrition.

The FDA and Association of American Feed Control Officials (AAFCO) have guidelines in place for a reason: they work.

As always, go over diet and nutrition with your vet – he or she knows best.
