Americans Spend Billions Because Our Pets Are Important to Us

Actually, they’re not just pets, they’re members of the family. 70% of U.S. households own a pet, which equates to 90.5 million homes. So much so that pet owners in the United States spent $50 billion on pet food in 2020 alone according to the American Pet Products Association. And that’s just food!

Overall, we spent a massive $103.6 billion on our pets over the course of a year. Surprisingly, very little is known about pet food ingredients and accompanying laws, but there’s a wave of awakened pet owners who are eager to become informed on the matter.

Mamavation is about to cover these topics to help you make better & safer consumer choices in terms of dog food. We will focus on product contamination, ingredient quality, and a shocking lack of oversight by the Feds. Then at the end of this investigation, we will share our rankings of all the most popular dog food brands.

Dangerous Contaminants and Adulterated Ingredients in Pet Food

There are many examples of recalled pet food due to ingredient contamination. In a recent case brought by Purina, the United States District Court in St. Louis handed down a verdict on Wilbur-Ellis Feed and Diversified Ingredients ordering them to pay a whopping $7 million for their involvement in selling poultry feathers, heads, bones, feet, and entrails as high-quality poultry meal to Blue Buffalo and other pet food manufacturers.

There’s a problem with toxic chemical contamination as well. According to research conducted by Cornell University, glyphosate (the active ingredient in RoundUp) is pervasive in the pet food industry. Scientists tested 18 different commercial cat and dog foods, and ALL of them contained detectable glyphosate. Their findings also connected the presence of glyphosate to the fiber content of the food which suggests a plant-based origin. This is not surprising because we already know that crops are often sprayed heavily from beginning growth to end harvesting, and this is just more proof that this toxic, persistent herbicide remains in the final product.

Surprisingly, the concentration of glyphosate in pet foods could very well result in exposures up to 12x higher than that of humans! Scientists also noted the limited available information about the effects on glyphosate on cats and dogs which means we really have no idea how bad this is affecting them. Unfortunately, the brands that were tested have not been released. Don’t worry, we made sure to ensure all our “best” brands use only organic legumes.

In addition, there are other dangerous contaminants like pentobarbital, the drug used to euthanize animals. In fact, the FDA put out a report that says, “There appear to be associations between rendered or hydrolyzed ingredients and the presence of pentobarbital in dog food. The ingredients Meat and Bone Meal, Beef and Bone Meal, Animal Fat, and Animal Digest are rendered or hydrolyzed from animal sources that could include euthanized animals.” This led us to an automatic demotion of any brand with products that contained any of these ingredients.

Dog Food Ingredients to Avoid

These are ingredients commonly found in dog foods across the board. Many of them are principal ingredients and originate from unknown sources which makes them inherently dangerous for consumption. The truth is dogs have sensitive stomachs and digestion and depending on what nutrients you feed them or whether they have food allergies or sensitivities, you can make them pretty miserable. Pay close attention to the breed of your dog and what types of health conditions they suffer from to give them the best food.

Here are some basic principles to guide you when you are looking for wet dog food, dry kibble, or whatever else you need for your dog. Please talk to your veterinarian about your dog’s diet before making any changes.

  • All types of meat by-products, by-product meals, meat meals, and meat and bones meals can be sourced from any number of places including diseased animals, non-slaughtered dead animals, euthanized animals, or decomposing animals, which means they may also be contaminated with the euthanasia drug, pentobarbital. By and large, the source of the meat is a mystery and high-quality dog food will never include this.
  • Poultry and animal fat, animal digest, and porcine/pork plasma have unknown origins and can be sourced from diseased animals, non-slaughtered dead animals, euthanized animals, or decomposing animals, which means they may also be contaminated with the euthanasia drug, pentobarbital, and the porcine epidemic diarrhea (PED) virus. High fat diets can also cause pancreatitis in dogs.
  • BHA and BHT are toxic preservatives and endocrine disruptors and are reasonably anticipated to be carcinogenic as stated by the NIH National Toxicology Program.
  • Natural flavors is an umbrella term that legally hides an alarming variety of ingredients (some chemically distilled) through laws designed to protect trade secrets. By definition, it’s any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional. That can include a LOT of different substances.
  • Carrageenan is irritating to the digestive system and can cause diarrhea
  • Garlic & Onions can be poisonous & toxic to your pup in larger quantities. Onions & garlic contain disulfides and sulfoxides (thiosulphate), both of which can damage red blood cells and cause anemia in your dog. Signs may include weakness, vomiting, and trouble breathing.
  • Yeast can cause digestive discomfort to dogs with lots of gas and farting. In severe cases, too much yeast can lead to rupturing the stomach and intestines.
  • Artificial colors and flavors should be avoided because they’re synthetic ingredients that can come from anything that is inedible (even petroleum) and is processed to create chemicals of flavorings and colors.
  • Too Much Liver or other organ meats can be problematic too. You can give a little bit to your pup, but liver contains quite a bit of vitamin A, which can adversely affect your dog’s joints and cause gastrointestinal problems. Unfortunately, this was too common in dog food to avoid, so we suggest you vary flavors when you feed your pup.
  • Too Much Pea Ingredients and other legumes can have other ingredients that interfere with glucose regulation and lead to intestinal irritation if eaten in large quantities over long period. Because of the “grain-free” dog food movement, this is impossible to avoid, so we again suggest you vary flavors. Also, make sure if you see legume-based ingredients, they are using an organic ingredient because glyphosate is high in legumes.

Lack of Oversight in Pet Food Manufacturing

Can you believe the FDA has actually admitted that they don’t actively enforce the law with pet food? The United States law, Title 21, Chapter 9, Subchapter IV, Section 342 states that food (including animal/pet food) is considered adulterated if it is sourced from a non-slaughtered animal.

But in 2016, the FDA openly stated they will continue to “…allow animals that have died other than by slaughter that are further processed; we will allow those ingredients in pet food [because] processed pet food, including pet food consisting of material from diseased animals or animals which have died otherwise than by slaughter, goes through a kill step, such as heat processing, which is designed to kill harmful bacteria.” Nasty.

Any pet food containing one of the following ingredients could contain diseased animal material, non-slaughtered dead animal material, euthanized animal material, and/or decomposing animal material, and there’s no source requirement: chicken by-products, chicken by-product meal, turkey by-products, turkey by-product meal, meat meal, beef meal, lamb meal, venison meal, meat and bone meal, animal fat and animal digest.

Another problem is regulations do not require pet food to disclose what percentage of the total pet food is present. That information is considered a ‘recipe’ and would be proprietary. What they do mandate is that pet food ingredients be listed in order of pre-cooking weight, with the heaviest ingredient first.

What do “natural” and “organic” Labeling Terms Mean on Dog Food Labels?

According to the Association of American Feed Control Officials (AAFCO), the definition of “natural” means the following:

“a feed or feed ingredient derived solely from plant, animal or mined sources, either in its unprocessed state or having been subject to physical processing, heat processing, rendering, purification, extraction, hydrolysis, enzymolysis or fermentation, but not having been produced by or subject to a chemically synthetic process and not containing any additives or processing aids that are chemically synthetic except in amounts as might occur in good manufacturing practices.”

Typically this really means the product is “free-from” corn, wheat, soy, food processing byproducts, and artificial colors. But because this marketing term is not regulated, it could really mean anything, so make sure to read the ingredients to be sure you understand what you are buying.

Organic to the rescue! In terms of “organic,” there are very specific definitions and terms regulated by the USDA. AAFCO explains that to be labeled “organic,” animal foods must meet the U.S. Department of Agriculture’s production and handling standards for organic foods. This is primarily concerned with human-grade food, but in terms of dog food is the same.

USDA organic products must contain at least 95% organic ingredients to receive the organic seal. These ingredients must be grown without certain pesticides, artificial fertilizers, genetic modification, irradiation, or sewage sludge. Organic animal ingredients, including meat & eggs, must come from animals raised on organic feed, given access to the outdoors, and not treated with antibiotics or hormones.

FDA Has Concerns About “Grain-Free” and “Exotic” Dog Foods

There may be a problem with all this “grain-free” dog food. The FDA is looking into a possible link between DCM (dilated cardiomyopathy) in dogs and the ingredients in certain boutique and grain-free pet foods.

In a 2018 article in the Journal of the American Veterinary Medical Association, they explained the issue is not just grain-free diets, but rather, “BEG” diets (boutique companies, exotic ingredients, or grain-free diets). It’s an entire movement of new ingredients.

“The apparent link between BEG diets and DCM may be due to ingredients used to replace grains in grain-free diets, such as lentils or chickpeas, but also may be due to other common ingredients commonly found in BEG diets, such as exotic meats, vegetables, and fruits,” Freeman wrote.

Canine DCM is a heart disease in which the chambers of the heart become dilated and later the heart muscle becomes weakened and leading to heart attacks. Typically, this was only a genetic disease that was seen in Boxers, Great Dane, Newfoundlands, Irish Wolfhounds, Saint Bernards, and Doberman Pinschers, but now that isn’t the case.

Grain-free diets are full of legumes, which are also known to have higher levels of glyphosate, an herbicide also used for the desiccation of crops. Therefore, do not change your dog’s diet without a recommendation from your veterinarian.

Wanna Try DIY Dog Food?

Have you ever considered making your dog’s food? You’ll need to consider how many vitamins, like vitamin e or vitamin a, niacin, calcium, minerals, fatty acids, omega-3s, & calories they are eating. You’ll also need to involve your veterinarian for additional monitoring and advice. However, when you make the dog food yourself, you won’t need to worry about fillers or pesticides (if you are using USDA organic food). You’ll be able to use some of the best ingredients like barley, brown rice, organic chickpeas, bison, lentils, and free-range chicken.

Maintenance Energy Requirement

The first thing to do is to confirm how many kilocalories your dog requires to be fed on a daily basis. This is referred to as the Daily Energy Requirement or DER. You then take the total calorie requirement and divide it by the number of meals (usually 2 plus snacks) fed to your dog daily. Make sure to include all treats and snacks in the total.

It is always recommended that before making changes to a dog’s current diet you discuss this plan with your veterinarian.

Dog’s Activity Level

Most pet foods come with feeding guidelines that are located on the packaging. It usually provides a large range of weight from “30 to 50 lbs.” Other dog food companies ask about activity levels like “average or highly active” but what is the most important part of the scenario is not really all this, but two things:

    • How much your dog weighs.
    • Body Condition Score (scores from 1 severely underfed to 9 severely 0bese): The body condition score is a hands-on assessment of weight and the dog’s physique. It’s based on a dog’s frame as opposed to body mass.

Obviously, a dog having a higher body condition score will not need as much food. Purina has a body condition score chart and scores the dogs in three groups of underweight, overweight, and ideal weight.

  • 1-3 is considered underweight or too thin.
  • 4-5 is considered ideal.
  • 6-9 is considered overweight or too heavy.

Monitoring Dog While DIY Feeding to Ensure They Get Proper Nutrition

It’s important to monitor your dog if you decide to DIY feed them. You’ll need to stay in close contact with your veterinarian regarding changes you’ve noticed about your pup, good or bad. Here are some of what you will need to do:

  • Weigh your dog once per week
  • Give your dog a body condition score every week
  • Monitor closely for vomiting or diarrhea, which could mean your dog is sensitive to an ingredient. Contact the office with news about changes.

However, don’t sweat it. If you are committed to this change, you’ll work it out. But we do not recommend something like this unless you involve your veterinarian.

Basic Nutrition for Dogs — Dog Food 101

Just like us, dogs need certain types of nutrients each day to thrive. Human needs are very different than dog needs, so it’s important for your dog to get his own food. Feeding an incomplete or imbalanced diet can lead to vitamin and nutrient deficiencies.

Each dog needs enough calories to meet its energy requirements. A dog’s daily caloric need depends on the dog’s life stage and activity level.1 Your veterinarian can help you determine how many calories your dog needs each day.

  • 10% protein, such as chicken, turkey, fish, lean beef, salmon, bison, venison, or other such meat.
  • Up to 50% carbohydrates, such as rice, certain types of pasta, potatoes, sweet potatoes, and pumpkin. This also provides some fiber
  • About 2.5-4.5% fiber, which can come from vegetables like organic peas, green beans, carrots, spinach, squash, or other veggies. It’s important to ensure the legumes are organic to avoid high levels of glyphosate.
  • Vitamins and mineral supplements are important to ensure dogs are getting everything they need. If this is not included, talk to your vet about what is needed to supplement.

If you are ready to get started cooking for your dog, the first step is to talk to your veterinarian. Your vet may have recipes for you to try. We’ve also collected some books for you here on how to get started.

Supplementation for Dogs

Dog may need additional supplementation when their dog food does not include it. Make sure to talk to your vet about what your specific breed needs. Some common supplements include:

  • Calcium
  • Vitamin E
  • Sardines in water or fish oil capsules daily

Overweight Dogs–Weight Management Tips

When dogs become overweight, they suffer from some of the following health conditions:

  • Diabetes – Carrying extra weight leads to insulin resistance, which is when the body doesn’t normally respond to insulin.
  • Arthritis – Being overweight puts unnecessary stress on joints and discs in the spine, which can lead to joint degeneration.
  • Respiratory Issues – It becomes harder to breathe when our dogs have extra fat around their airways and chest. They have to work harder to breathe.

Obviously, no one wants their dog to suffer. There are simple tips and tricks to helping your dog maintain a more healthy weight.

  • Increase their activity level.
  • Measure their food on a kitchen scale.
  • Try to find additional ways you can treat your pup that don’t include treats. Perhaps a long walk?
  • Instead of packaged treats, try substituting them with some real foods.
  • Stay clear of salt
  • Make sure the entire family is on board and isn’t sneaking them treats.

Mamavation’s Investigation of Dog Food Brands

Now we get to the nitty-gritty. We looked at over 260 different products and each one is assigned to one category: “not our favorite,” Better, Best — according to ingredient content. Note that we looked at 1-3 samples of each brand’s adult dog food formulas, both wet and dry when possible, however, there are other formulas offered by each company. Please note that some brands found products in several categories so please pay attention to products and ingredients.

Not Our Favorite Dog Foods

The massive list. This is the category for products that contain the worst ingredients. Every one of them has multiple ingredients from unknown and/or potentially contaminated sources including animal fat, animal digest, flavors, by-products and meat meals, toxic preservatives, added sugar, carrageen, and possible GMO ingredients including corn, soy, and canola. We found that many dry dog foods contain mysterious meat meals which automatically knocked them down to the bad category. Unfortunately, this list includes the most affordable brands that you find in common pet and grocery stores around the country. Also interestingly, a convincing label that has phrases like ‘all-natural,’ ‘ultra-premium,’ and ‘complete nutrition’ had little to do with the quality of ingredients. Please note that some brands have products in each category, so pay attention.

Better Dog Food

The Better category contains products that have very few questionable ingredients. These foods aren’t perfect, but they’re far better for dogs than those listed in the “not our favorite” category and are nutritionally acceptable. Here’s where we start seeing a sharp uptick in wet vs dry dog food. It’s clear that wet foods have better quality ingredients, fewer additives and would seem to be overall healthier with the added water content. Please note that some brands had products in each category so please pay attention.

non-toxic dog food investigation

Best Dog Food

As usual, our Best category is the shortest list. These dog foods make the cut because they have more quality, whole food ingredients, no additives, and are meat-based. Some of them also contain organic meat and vegetables, but you’ll not find meals or by-products. All legumes here are organic in order to avoid high levels of glyphosate contamination. You’ll notice that there are no conventional dry foods in this section. We also wanted to warn you that most of these brands do not include additional vitamins & minerals. Some of them do, but not all of them. Please contact your Veterinarian to see if supplementation of additional vitamins and minerals are needed.

    Have you done any testing on vegan dog food? I have a dog with crazy allergies and have her on veggie diet. In my search for dog food that was truly veggie, I only found a vegan brand called v-dog.
