Why Choose Fish-Based Dog Food?

  • Protein-rich- fish is a lean source of high-quality protein necessary for all bodily activities. As such, it can help your pooch maintain healthy body weight and lean muscle mass.
  • Rich source of omega-3 fatty acids- different types of fish especially salmon are a natural source of omega 3 fatty acids such as EPA and DHA. These fatty acids are said to be great for your pet’s joints, coat, and skin.
  • Amino acids- fish-based dog food provides all the essential amino acids your pooch needs in his diet. These amino acids are required for regulating hormones and building cartilage.
  • Low mercury- if you choose a salmon based dog food, then you can rest assured that it is very low in mercury. Therefore, you don’t have to worry about your canine companion ingesting unhealthy levels of mercury.
  • High in vitamins and minerals- fish-based dog food contains various vitamins and minerals including Vitamin B12, Vitamin D, magnesium, zinc, potassium, and among others.

What to Consider When Buying the Best Fish-Based Dog Food

Fish is the preferred protein source for dogs especially those allergic to meat. However, in most cases, fish is used in combination with other protein sources. As such, there are a couple of things you may need to look out for when buying fish-based dog food. These include:


The fish-based dog food should not contain any fillers, colors, artificial preservatives or flavors. Such fillers may trigger allergies and even cause digestive problems in some pets. Instead, consider foods that make use of ascorbate or tocopherol as preservatives because they’re naturally found in foods.

Complete nutrition

The fish-based dog food you choose should be wholesome and complete. It should have a balanced mix of vitamins, minerals, proteins, carbohydrates, and essential fats. However, the first ingredient should always be real fish.

Real Fish

You need to check the label of the food to confirm that the food is made from real fish and not fish flavoring. Artificial fish flavoring will not have any health benefits to your doggie. Some of the best types of fish include salmon and whitefish.


Grain-free dog food may not always be the best option for all dogs. However, it can often be beneficial for doggies with allergies. Besides, it can help with a ton of digestive problems.

Luckily, most of the fish-based dog foods in this review happen to be grain-free. Such foods don’t contain soy, corn, or wheat.

Dog age

You need to choose a fish-based dog food that is according to your dog’s age and energy needs. Most dog food brands are usually labeled with “small breed”, “puppy breed” or “adult breed”. This is to indicate the stage the whitefish dog food is suited for.

However, there are also those brands that are designed for use by all breeds throughout their entire life stages.
