Today, dog owners have a huge variety to choose from when it comes to what to feed their canine companions. While we all want our pups to live long, healthy lives, it is important to be informed about what we feed them. Unfortunately, there are a number of ‘trendy’ and ‘fad’ diets, and a great deal of inaccurate information online. One can easily become confused or even misled by slick marketers or uninformed influencers when it comes to your pet’s health and well being.

When it comes to dog food diet fads and trends, raw food has attracted attention and is widely available in pet stores. But does eating raw really benefit your dog’s health? Could a traditional kibble diet made correctly with premium ingredients, actually provide better nutrition and overall health at a fraction of the cost? In this article, we will dive into the raw vs. kibble debate by defining each way of feeding your dog and showing you why one is clearly the better option if done properly.

If you spend much time at all in pet stores or researching natural pet food options for your precious pup, chances are you have stumbled upon the phrase ‘raw food diet’. Raw food proponents theorize that since the diet of wild canines (like hyenas and wolves) consisted mainly of raw meat and bones, that today’s domesticated dogs should be on that same kind of diet. (Even though our dogs descended and evolved greatly over the past 12,000 years.)

If you are not convinced that your dog is not the same as a wolf, consider these indisputable scientific facts:

  • There are 36 parts of the genome (DNA) that differ between dogs and wolves, 10 of which play a critical role in starch digestion and fat metabolism. (A genome is an organism’s complete set of DNA, including all of its genes).
  • These genetic differences in the genome between dogs and wolves include the ability of dogs to digest carbohydrates and fat (for energy), which was a crucial step in the early domestication of dogs and enabled dogs to obtain energy efficiently from food. (Raw diets generally ignore carbohydrates, which means your dog’s body has to work harder to obtain the necessary energy the brain and organs need to survive. That also means the organs are getting taxed by working to derive energy from meats.)

Typically, a raw food diet consists of raw meat and bones supplemented with fresh fruit or vegetables. There are two main types of raw food diets: commercial and home-prepared. The former tends to come in patty or nugget form and includes mostly raw meat, with some kind of raw fruits and vegetables mixed in.

Home-prepared raw food diets for dogs vary from one household to the next. Households who choose to feed their pup a home-prepared raw meal must be prepared to set aside the time to put together multiple meals per day consisting of raw meat, bones, and supplemental ingredients. While this method of feeding dogs attempts to mimic the diets of wild canines over 12,000 years ago, it is time-consuming, extremely expensive, and difficult to be consistent – among an array of other potential health and safety issues. It is worth mentioning here that while it is trendy for marketers to tell you that “your dog is a wolf, so feed it like one” the fact is today’s dogs have been domesticated for well over 12,000 years or so and as such, have dramatically different lifestyles, differences in how they procure food, and also have different energy requirements. In the wild, dogs would travel in packs, sometimes not eat for days in between hunts, and were extremely active. They also had much shorter lifespans from living outdoors and being subjected to the elements, pests, and predators. Therefore how and what they ate then is very different from the lifestyle and nutritional requirements of domesticated dogs today.

Kibble was first invented 50-60 years ago, with the intent to provide a consistent method to feed dogs and cats, and since that time, it has become the most popular choice of giving our pets the nutrients they require. While dry kibble as a meal may not seem to be particularly appetizing to the human palate, understanding the process of how kibble is made can help us realize why kibble dog food and kibble cat food is the best diet choice for our pets.

Like most things in life, there can be huge differences in the quality of products, and pet food is no exception. Several factors can affect the quality of pet food, including: 1) Experience of the nutritionist who developed the diet, 2) Quality of the raw ingredients used and 3) The integrity of manufacturer and the methods they follow to blend, cook, and prepare the kibble.

In order for any pet food to be sold in the US, it must state on the label if it is complete and balanced, and also whether it adheres to the AAFCO (Association of American Feed Control Officials) guidelines for the species. The formula should be developed by an experienced nutritionist who understands how various ingredients work together in combination to provide the nutrient requirements. Kibble provides convenience to pet parents to feed their pet each day, and peace of mind that their pet can be healthy by consuming the diet. When a nutritionist creates a kibble formula, they first take into account the needs of the animal, the nutrient values of the raw ingredients, and how cooking those ingredients will affect the final product. Experienced nutritionists take into account cooking temperatures, storage conditions and shelf-life timelines that retailers and consumers require for pet foods. So the formula itself, and the production process anticipate various conditions from the raw materials all the way to the end of the shelf life to ensure that your pet will have the guaranteed level of nutrition required, regardless of when the kibble is consumed within the shelf-life timeline.

Much like making a cake in your home, to produce kibble, manufacturers first start by blending and mixing together the various raw ingredients. Depending on the specific formula, these ingredients might include a variety of specific meats, fish, poultry, fiber sources, carbohydrates, vegetables, fats/oils, and supplemental vitamins/minerals. The mixture is put through an extruder or oven, which cooks the blended ingredients and shapes the pet food into bite-size pieces. After cooking, the moist kibble will move slowly along a conveyor with heated air dryers to slowly reduce moisture to create the dry kibble that we are familiar with purchasing from the pet store. During production, the extruder has computer-automated sensors that monitor the key requirements such as protein, fat, fiber, moisture and the “percent cook” of the blend. This ensures that the kibble produced meets the specifications set by the nutritionist. If there are variations, the operator will stop the extruder, make adjustments, and then remove any production that was below the specifications.

While understanding the manufacturing process behind making kibble is interesting, it also helps us to understand that dry kibble as a food source is not so unusual after all. In fact, if a diet was made specifically for humans, we could also be completely capable of living a healthy life eating only kibble (If it was formulated to meet human nutrient requirements which are different from those of dogs and cats). This realization can help us understand the next important truth about kibble pet food: Not all kibble is created equal.

Kibble has been scientifically proven to be more efficient when it comes to providing your pup with the proper nutrition in every bite. Now, let’s take a look at why the risks of the raw food diet make it an unsafe choice.

Risks and Downfalls of the Raw Food Diet

Safety Risks

Simply put, a raw diet is unsafe for dogs, cats and humans according to the FDA, noted scientists and many veterinarians. Studies show that raw dog and cat foods have been found to contain an array of harmful bacteria including Salmonella, E. Coli, Campylobacter, Clostridium botulinum, and Staphylococcus aureus. All of these are known to be human, feline, and canine pathogens. Your pup can shed these bacteria in his stool, which can be transferred to areas around the house as your pet moves about.

The bacteria can be picked up by human members of the household, making them very sick. These bacteria can pose a very serious health risk to children, the elderly, and anyone who is immunocompromised. Additionally, bacteria like Neospora caninum, Nanophyetus salmincola, and Trichinella spiralis are frequently found in raw meats and are capable of making the dogs themselves very sick. All of these bacteria are potentially life-threatening for your dog. In particular, if your home has children, infants, elderly, a pregnant woman, or anyone with a weakened or compromised immune system, raw pet food is especially unsafe and risky.

Case report studies of animals eating raw diets showed contamination with Salmonella, E. coli, Campylobacter jejuni or Toxoplasma gondii and increased numbers of infections attributable to Echinococcus multilocularis. These bacteria and pathogens also negatively affect the microbiome of the dog or cat by altering the balance of bacteria in the gut, and in turn, negatively affect gut health. Scientific published studies that document this include: Śmielewska-Los et al., 2002, Dubey et al., 2005, Lopes et al., 2008 Lenz et al., 2009, Taylor et al., 2009, Antolova et al., 2009.

Over the years, some raw food brands have implemented either irradiation treatment or high-pressure pasteurization (HPP) to their products before shipping as a kill step for any pathogens. Due to the nature of raw uncooked meats, once raw food diets are defrosted in your home, there is a significant risk of dangerous bacteria and pathogens developing very quickly. This is why raw food marketers direct customers to use the defrosted food quickly and not leave the raw defrosted food in your pet’s bowl longer than the immediate feeding time. Raw food serving also requires that you clean and disinfect working surfaces and utensils. Your pet’s food bowl must be thoroughly washed and disinfected after they finish each meal to prevent the growth and spread of harmful bacteria.

While there are plenty of personal opinions either way, among pet store owners, veterinarians, and bloggers, the facts speak for themselves regarding risks and nutritional deficiencies of feeding raw dog and cat foods. The FDA has issued numerous warnings regarding the risks of feeding raw pet food diets, such as this arti
