For many of us, our dogs are our best friends in life, but we don’t always know how and what we should feed them. With the vast variety of dog food currently available, it can be a daunting task to choose which is best suited for your canine friend.

Factors such as breed, age, activity levels, and sensitivities or allergies can and should have an impact on your choice of dog food. Let’s dive into the world of dog food and break it down into manageable and understand steps so you can make more informed decisions.


Dog Nutrition

Dogs and humans are both omnivores, and so they share nutritional similarities. An omnivores diet should consist of a mix of the three core nutrients: protein, carbohydrate, and fat.  A healthy balance of these three core nutrients is critical to your dog’s health. Let’s go through them one by one and find out why they are essential.

Protein for Dogs

Protein should be at the core of a dogs nutrition and is required for all aspects of growth, repair, and maintenance. Protein also plays an important role in the maintenance of a dogs immune system.

The quantity of protein required in a dogs diet can vary significantly. The biggest factor is the activity of a dog. The more active they are, the protein they will require to effectively maintain their muscles and cells. 

The opposite is also true. Inactive dogs require lower levels of protein as there are minimal repair and maintenance occurring.

It is important to note that excess protein can be burned as calories immediately or it can be theoretically converted into fat for storage. However, extremely high proportions of protein are likely to lead to waste as some of this protein will be excreted through urine.

Carbohydrates for Dogs

Carbohydrates are not required within a dogs diet, but that doesn’t mean they are a negative addition. They can provide a source of energy and dietary fiber which can play a critical role within a dogs health.

As dogs were domesticated from Wolves, they adapted to a lack of regular meat and fish by being able to consume large volumes of plant-based material. This adaption is what allows dogs to effectively digest carbohydrates.

The key to carbohydrates is choosing high-quality ingredient to provide them. Whole vegetables and some grains should are ideal. Examples include Sweet Potatoes, Pumpkin, Chickpeas, and Oatmeal.

Most grain-free dog food tends to use legumes such as Peas, Chickpeas, and Lentils. 

Lower-quality carbohydrate ingredients tend to be by-products, processed ingredients or extremely dense sources. Examples could be grain or legume flours such as Pea Flour and Rye Flour or starches such as Potato Starch.

Unfortunately, low-cost dog food brands tend to use very large proportions of carbohydrates in their dog food. The primary driver behind this is that they are low cost, abundant and can allow for the dog food to be stored for a prelonged period of time.

Fat for Dogs

Ideally, fat should be your dog’s primary source of energy as it is over twice as concentrated a source of energy when compared to protein or carbohydrates. 

However, fat’s aren’t just used for energy and are also crucial for development and the maintenance of your dog’s cells, muscles, and tissues.

The volume of fat in a dogs diet should vary depending on their lifestyle in a similar fashion to protein. Active dogs should have a higher proportion of fat as they will require an energy source and will be able to easily expend the energy.

However, less active dogs may want a lower proportion of fat in their diet. This is as if they overconsume a high fat diet they may suffer from weight gain or obesity.

The best type of dietary fat for dogs is animal or fish fat. This  is a dog’s natural source of fat for which their digestive system is designed to digest.

Fat from fish ingredients is especially beneficial as it contains high levels of the Omega 3 and 6 fatty acids. These fatty acids are known to provide a range of health benefits including improved cognitive function, a healthier skin and coat, and a reduced risk of heart disease.

Guaranteed Analysis

Dog food has come along way over the last few decades, and all dog food brands (in North America and Europe) should have a Guaranteed Analysis displayed on their packaging. You can use this analysis to see the nutritional breakdown of the dog food in question. The nutritional values that must be displayed on dog food include the following.

  • Protein (Min) %
  • Fat (Min) %
  • Fiber (Max) %
  • Moisture (Max) %

Some dog foods may also show additional information such as the content of certain vitamins and minerals. Examples of this include:

  • Phosphorus (Min) %
  • Calcium (Min) %
  • Omega 3 Fatty Acids (Min) %
  • Omega 6 Fatty Acids (Min) %

It is very important to note that these values are a mixture of Minimum and Maximum percentages. For the case of protein and fat, it is to say that the dog food formula will contain at least this proportion. However, it is likely to contain more as manufacturers have to list a figure that is always correct no matter the variance.

For the values that are labeled as Maximum, such as fiber and moisture, the actual values are likely to be lower. Despite this, these minimum figures are likely very close to reality as it would not be financially wise to heavily reduce either of these.

At Pet Food Reviewer, we base our nutritional analysis on these crude minimum figures as this is the only figure that we can use with certainty.

However, some dog food brands have chosen to provide additional and more detailed nutritional information. This may include the average nutrition provided or the nutrition provided on a dry matter basis.

Dog Food Ingredients

Commercial dog food should contain an exact breakdown of its ingredients in descending order. This means that the most abundant ingredients will be towards the top of the list and the least abundant towards the bottom.

This ingredient list should allow you to quickly analyze what is present in dog food and better understand its quality. You should take the opportunity to attempt to spot or highlight any questionable or harmful ingredients that could have a detrimental effect on your dog’s health.

Categorizing dog food ingredients into high-quality or low-quality is no easy feat. There will always be a fierce debate, especially from manufacturers about is suitable for a dogs diet.

At Pet Food Reviewer, we are building a comprehensive group of posts that analyze specific ingredients, breaking down their positive and negatives features.

A few examples of these posts to date include;

In addition to these articles, we have listed a selection of ingredients that are considered by many to be high-quality, low-quality and potentially dangerous or harmful.

High-Quality Ingredients

  • Chicken
  • Turkey
  • Salmon
  • Mackerel
  • Trout
  • Beef
  • Lamb
  • Sweet Potatoes
  • Pumpkin

Low-Quality Ingredients

  • Meat By-Products
  • Corn
  • Rye
  • Pea Protein
  • Potato Starch
  • Artificial Flavours

Dangerous / Harmful Ingredients

  • BHA
  • BHT
  • Ethoxyquin
  • Artificial Dyes

Almost all whole meat and fish ingredients would be considered to be high-quality additions to dog food. Meat and Fish Meals are also regular additions and while many consumers are put off by these, they are in fact still high-quality.

In short, Meat Meal has had its moisture removed which allows it to be a far denser source of protein and fat than whole meat.

Grain and Vegetable By-products are considered by most to be low-quality ingredients. Examples including those listed above are Pea Protein, Pea Flour, Potato Starch, Tapioca Starch, and Rye Flour.

Allergies or Sensitivities

Dietary allergies, sensitivities, and intolerances are becoming increasingly common in pets such as dogs. However, the dog food market is adapting to help combat this by providing dog food designed for dogs with allergies.

We have a range of articles that explain in detail how to approach feeding a hypoallergenic dog and what foods are available that do not contain common allergens.

A few examples include:

Novel Meats are uncommon or unique meat ingredients that are often used in Hypoallergenic Dog Food. The logic behind this is that because a dog may not have been exposed to them before, they are less likely to be allergic.

We’ve written a number of articles discussing common Novel Meats.

Examples include:

One of the great benefits of the modern dog food market is its huge variety. Whether it be at a grocery store, an independent pet store or a large commercial pet store there is always aisles of choices.

Dry Dog Food

Dry dog food is the most widespread and common form of dog food and can also be known by the name of kibble. Its most significant advantage of dry dog food is that it can be safely stored for long periods of time and comes in a very large array of flavors and varieties.

Most dry dog foods are balanced to provide your dog with complete nutrition without the need for any supplementary food.

However, the most common disadvantage of dry dog food is that it often contains processed ingredients or fillers which are not ideal or suitable for your dog’s diet.

This is why it is of vital importance to choose a high-quality dry dog food that combines high-quality ingredients with balanced nutrition.

Canned/Wet Dog Food

Wet dog food is commonly stored within a can and contains a much higher percentage of moisture than dry dog food.

Just like Dry Dog food, most wet dog food is designed to provide complete nutrition for your dog without the need for any additional supplementation.

One benefit of wet dog food is that they tend to contain fewer fillers or processed ingredients with some recipes containing none at all. However, always check the packaging to ensure this as some wet foods will still contain fillers and processed ingredients.

Puppy Food

Puppies need a diet with a different nutritional profile compared to adult dogs. This different balance of nutrition is critical to ensure that your puppy grows and matures into a healthy adult dog.

Examples of this differing nutrition include a careful balance of Phosphorous and Calcium for large breed puppies and a larger proportion of protein for all puppies.

Both dry and wet puppy food is widely available, and they share many traits of adult dog food.

Some varieties of dry dog food for puppies are smaller in size than traditional dry dog food to allow for ease of consumption.

Senior Dog Food

As dog’s age, they can benefit from a different balance of nutrition. Senior dog food recipes can provide them with this unique balance of nutrients that are more suited to elderly dogs than traditional adult dog food.

Also, senior dog food formulas can contain ingredients that can maintain aging dogs joints, bones, and the digestive system. This can include nutrients such as the Omega Fatty Acids.

However, many the majority of older dogs will still fare well on their existing adult recipe.

Dry and wet varieties of senior dog food are commonly available from a variety of brands.
