When you look at the evolution of dogs, they have certainly evolved and differentiated physically quite substantially over time.
Despite physical characteristics that differentiate one breed of dog from another, dogs and wolves belong to the same genus (Canis) and share 99.9% of their DNA. These similarities can be identified in notable shared characteristics, like digging and foraging, social behaviours and ways of communicating.
How a dog’s physiology directs what they should be eating
When it comes to diet, the jaw structure of canines gives us an indication of the diet that matches their physiology and the evolution of dogs in the wild to eat and thrive. Dogs’ teeth and jaws are adapted to a carnivorous diet with teeth that are designed for capturing and dismembering prey.
The length and function of the dogs’ digestive system also indicates that they were born to eat raw meat and absorb their nutrition primarily from the body parts of their prey with a small additional component of their diet coming from plant matter which includes grasses, seeds and fruits.
The benefits of eating raw ‘prey’ for dogs
To us humans, some of the more “undesirable” parts of an animal are the most delicious and nutritious to canines! In the wild, the first things to go are the internal organs of prey which harbour the most concentrated levels of vitamins and minerals. Organs like liver, kidneys, heart and brain are concentrated sources of fat soluble vitamins like A, D, E and K.
Wolves will consume skin, fur and bones as well as muscle meat in their ancestral diet. In larger prey, the stomach contents may be shaken to remove the bulk of the contents as a natural precautionary instinct, but the lining of the digestive system which is rich in natural probiotics would be consumed.
With all of this in mind, a species appropriate diet takes into account the evolution of dogs and the evolutionary diet of canines. This is the modern version of the way our domesticated dogs would eat, if they were still in the wild.
What should a complete and balanced raw food diet include?
A species appropriate diet is broken down into is broken down into the following:
Raw Meat – Raw meat and fats derived from a variety of animals. These provide digestible sources of protein and iron and make up the largest portion of the diet. Protein is the largest source of amino acids which are used as the basic building blocks of cells in the body.
Offal – Organ meat including liver, kidney, heart, spleen and pancreas contain proteins and deliver a plethora of essential vitamins and minerals.
Bone – For concentrated levels of naturally occurring vitamins and minerals, nothing beats soft non-weight-bearing bones and cartilage for a natural source of calcium and phosphorus for teeth and bone health, zinc for immunity and omega-3 essential fatty acids to reduce inflammation.
Vegetable and fruit matter – Contain a naturally complete range of vitamins and minerals. Mostly green leafy and coloured vegetables, as well as fruits, ideally crushed and pulp to ensure better absorption. Together these supply antioxidants, phytonutrients, fibre and moisture as well as essential vitamins and minerals. Learn more about the benefits of vegetable and fruits here.
Other – In the wild this would be fur, stomach lining and organs like eyes and reproductive organs. In a modern day version of an evolutionary diet, ingredients like herbs, essential fatty acids, probiotics and prebiotics provide the nutrient profiles of some of these other components without quite so much of the “ick” factor.
Benefits of a raw food diet
- Naturally occurring nutrition in percentages and forms that nature intended in the evolution of dogs.
- None of the ingredients in raw evolutionary diets have been damaged or destroyed (also termed de-natured) or adversely affected by cooking so are at their most nutritionally dense, highest quality and therefore beneficial.
- If prepared correctly, nothing synthetic is added to a raw diet as synthetic ingredients have been associated with health problems in pets. This includes synthetic vitamins and minerals which are often required to overcompensate for the nutritional damage caused by cooking foods.
Health benefits of the evolutionary diet
- Superior joint and bone health
- Strengthened immune system
- Improved skin and softer, shinier coat – read more about that here
- Healthier teeth gums and fresher breath
- Reduced stool volume and odour
- Enhanced reproductive health
- Reduced body odour
- Increased resilience to parasites via enhanced immune function
Debunking the myths around bacteria
Some of the concerns when it comes to raw feeding are the presence of pathogens, the quality and source of the ingredients and the processing methods. These concerns are no different to the way we look at the food we eat ourselves.
The number one query when it comes to raw food is, “isn’t there higher levels of bacteria present?” and the answer is yes, absolutely. Unless raw food has been sterilised, which often reduces the nutrient levels as much as the bacterial load, there will most certainly be higher bacterial counts when compared to cooked foods. Are these bacteria bad? For our pets, no they aren’t. Read more about the benefits of bacteria here.
Why dogs can tolerate bacteria
The evolution of the dog means they have shorter digestive systems than we do, which are designed for foods to enter and exit quickly, not ferment like in a human digestive system. This reduces the time bacteria can sit in the system, replicate and thrive.
Furthermore, pets have highly acidic digestive systems with neutralise bacteria and dissolve bone, therefore more than capable of handling raw food. Even decomposing food poses little risk to our canine friends, often burying bones and food in the yard for a snack a little later on.
The time you might find your dog gets an upset stomach with a raw food diet, is if they are fed primarily a dry food diet, which makes their digestive system more alkaline, which is not natural for dogs. Read more about the impact of dry dog food here
Plus, it is important to always introduce any new diet to your dog slowly, so read more about transitioning your puppy or dog across to a new diet safely here.
Handling raw food
The handling of raw pet food is no different to the rules we should follow when prepping raw food in our own homes before cooking. It is fundamental that when handling any raw food that safe food handling practices are followed, including washing hands, kitchen tools and work-spaces following preparing raw food to ensure the risk of cross-contamination is eliminated.
