What You'll Learn
Dogs are omnivores, not carnivores
Dogs produce amylase, an enzyme that allows them to digest starches, in much greater quantities than wolves. This enables them to digest foods other than meat, such as grains and other vegetation. In fact, dogs have three genes related to starch and glucose digestion, which means they are well-adapted to eating grains and plant matter.
The intestinal length of dogs also supports their classification as omnivores. Carnivores have shorter intestines because meat is relatively easy to digest, whereas herbivores have longer intestines to break down plant material. Dogs have intestinal lengths that fall somewhere in between, which is a characteristic of omnivores.
Furthermore, while dogs do have long canine teeth designed for ripping and tearing meat, they also have different nutritional requirements that cannot be met by a meat-only diet. Dogs require a variety of vitamins, minerals, and fibre, many of which are found in fruits and vegetables. A meat-only diet can lead to calcium deficiency and other nutritional deficiencies, negatively impacting their health and wellbeing.
It is worth noting that some sources and experts argue that dogs are carnivores, despite their ability to consume and benefit from non-meat foods. This debate highlights the complexity of canine nutrition and the need for further research and understanding.

Meat-only diets can cause nutrient deficiencies
While meat-based diets for dogs might be rich in many nutrients and minerals, they are poor in digestible carbohydrates and fiber. A lack of carbohydrates can cause gastrointestinal problems and diarrhea. Meat-only diets can also cause hypovitaminosis A and D, which can lead to skeletal diseases and even chronic kidney disease.
In addition, a meat-only diet can result in protein deficiency, as the body is forced to use protein in the gluconeogenesis process to produce glucose. This can have various side effects, including a weakened digestive system and diarrhea.
Dogs require a variety of vitamins and minerals to stay healthy, and while meat provides many of these, it does not provide them all. For example, a meat-only diet can induce calcium deficiency and secondary hyperparathyroidism.
Dogs are omnivores by nature, and while they may enjoy and benefit from meat-rich diets, their nutrition should also include a range of fruits and vegetables. These provide additional vitamins and minerals, as well as fiber, which is crucial for maintaining a healthy digestive system.
If you are considering a homemade diet for your dog, it is important to work with a veterinarian or veterinary nutritionist to ensure that your dog's nutritional needs are being met. They can help you create a comprehensive recipe that includes all the necessary nutrients and can recommend a diet that suits your dog's specific needs, including their size, age, breed, and activity level.

A balanced diet includes meat and plant foods
Dogs are direct descendants of the gray wolf, which is a carnivore or meat-eater. However, as dogs became domesticated, they developed different traits of digestion and metabolism that cause many scientists to classify them as omnivores. Omnivores eat both plant and animal matter, and dogs can produce amylase, an enzyme that allows them to digest a diet rich in starches, which wolves cannot do.
A balanced diet for dogs should include meat and plant foods, with high-quality ingredients and the necessary proteins and fats. Meat provides essential amino acids, but a diet consisting solely of meat will not meet all of a dog's dietary requirements. Dogs can thrive without meat, but only if they are fed a properly balanced vegetarian diet. A plant-based diet can provide all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health and is often higher in fiber and phytonutrients. However, some vitamins, such as B12, may need to be supplemented.
For humans, a plant-based diet is flexible and can include vegetarian, Mediterranean, flexitarian, or semi-vegetarian diets, or simply limiting meat intake in favor of plant-based foods. A plant-based or plant-forward diet focuses on foods primarily from plants, including fruits, vegetables, nuts, seeds, oils, whole grains, legumes, and beans, while still including moderate amounts of meat, fish, eggs, and dairy. A flexitarian diet, for example, includes mostly vegetarian choices with some carefully chosen animal products mixed in.
There are several benefits to eating less meat. A plant-based diet is healthier than one heavy on meat, as it means consuming less saturated fat, which is linked to an increased risk of heart disease. It can also drastically increase your intake of fiber, which helps to lower blood pressure, reduce inflammation, and prevent cancer. Additionally, animal agriculture is a leading cause of methane gases in the atmosphere, which contribute to climate change.

Dogs need vitamins, minerals and fibre
Dogs, like humans, need vitamins, minerals and fibre to stay healthy. While dogs are direct descendants of the grey wolf, Canis lupus, a carnivore, they have since evolved into omnivores, capable of eating and benefiting from a more complex diet.
A dog's diet should include meat and plant foods, with the necessary proteins and fats. A meat-only diet will not meet all of your dog's dietary requirements. Dogs require certain essential amino acids in their diets, and while meat provides these, many plant proteins do not. Dogs can thrive without meat, but only if they are fed a properly balanced vegetarian diet.
Vitamins and minerals are crucial for the proper development and function of a dog's body. They are needed for the formation of bone and cartilage, nerve and muscle function, fluid balance regulation, the transportation of oxygen in the bloodstream and hormone production. Specific minerals must be present in the right amounts to provide optimal health. For example, magnesium aids muscle and bone development and is necessary to allow the dog's body to absorb calcium.
Fibre isn't an essential nutrient for dogs, but it is beneficial. It helps dogs have regular bowel movements and firmer stools. It can also help prevent constipation. However, there is little research on how much fibre a dog needs to maintain a healthy digestive tract, and this may vary from dog to dog.

Consult a vet before changing your dog's diet
Dogs are direct descendants of the gray wolf, which is a carnivore or meat-eater. However, as dogs became domesticated, they developed different traits of digestion and metabolism that cause many scientists to classify them as omnivores. This means that dogs can eat plant and animal matter.
Dogs produce amylase, an enzyme that allows them to digest a diet rich in starches, which wolves cannot do. On the other hand, dogs have long canine teeth designed to rip and tear meat, and shorter gastrointestinal tracts compared to other omnivores and herbivores.
Some people believe that dogs should eat meat because it is a more natural diet, with minimal processing and ingredients that are easier to understand. However, it is important to consult a vet before changing your dog's diet to include more meat or switching to an all-meat diet.
A balanced diet that meets the nutritional requirements of a dog includes meat and plant foods, provided the diet is made up of high-quality ingredients and includes the necessary proteins and fats. Meat provides essential amino acids, but a diet consisting solely of meat will not meet all of your dog's dietary requirements. Dogs can thrive without meat, but only if they are fed a properly balanced vegetarian diet.
If you are considering a raw meat-based diet for your dog, it is important to consult a veterinarian to ensure that the diet is complete and balanced, including calcium, vitamins, minerals, and taurine. Commercial raw frozen, freeze-dried, or dehydrated meat diets that are not complete and balanced require the addition of bones, a vitamin and mineral mix, vegetables, and fruit.
Some disadvantages of feeding a raw meat, complete and balanced diet to dogs include concerns over whether the diet is truly complete and balanced, especially with small companies that use only whole food ingredients and avoid synthetic nutrient supplements. There is also no good objective evidence that these diets improve the quality of dogs' lives or reduce the incidence of health problems.
Therefore, it is important to consult a vet before changing your dog's diet to include more meat or switching to an all-meat diet. A veterinarian can recommend a diet that best suits your dog's size, age, breed, and activity level, and help you transition your dog to a new diet while monitoring their health.
