Review Summary

Nutri Source РSeafood Select is a high-quality dry dog food. Its nutrient profile is above average, and it provides an above average proportion of protein and fat. This nutrient profile is unsatisfactory for the majority of dogs as the carbohydrate proportion is far too high. It has a range of high-quality fish ingredients such as Salmon. These ingredients do not provide a very satisfactory proportion of the Omega Fatty Acids. Also, the formula contains a Peas and Pea by-products. These contribute high-quality carbohydrates and dietary fiber. The limited number of ingredients present including fish and Peas could mean that this dog food formula is suitable for dogs with severe dietary allergies or sensitivities. However, for those without such issues, this is a reasonable dog food.

Nutritional Analysis

The ideal nutrition for a dog is entirely dependant on their unique circumstances. However, a high proportion of protein and fat combined with a lower proportion of carbohydrates is most appropriate nutrition profile for the vast majority of dogs. Dog’s are very capable of consuming a high proportion of carbohydrates, but a diet high in protein and fat is more appropriate and a better reflection of their natural ancestral diet.

Nutri Source Seafood Select Calorie Breakdown Chart

Carbohydrate Content Analysis

Dogs use carbohydrates as a simple energy source. Dogs do not require significant carbohydrates in their diet and they are commonly added to reduce cost and increase shelf life. As the chart above displays, a maximum of 42% of Nutri Source – Seafood Select calories are derived from carbohydrates. Please note that this is the maximum amount of carbohydrates as calculated by the guaranteed analysis. In reality, this value of carbohydrates is likely to be a lot lower. This is average for a Dry Dog Food.

The carbohydrates present in this formula are from ingredients such as Peas and Pea By-products. Whole Legumes such as these are considered high-quality sources of carbohydrates however the by-product are considered low-quality sources. This proportion of carbohydrates is not low and it is above what we would consider ideal. A lower proportion of carbohydrates would better mimic a dog’s natural diet.

Protein Content Analysis

Dogs use Protein for growth, development, and maintenance. Excess protein can be burned as calories. As the chart above displays, a minimum of 25% of Nutri Source – Seafood Select calories are derived from protein. Please note that this is the minimum amount of protein as calculated by the guaranteed analysis. In reality, this value of protein is likely to be higher. This is above average for a Dry Dog Food.

The protein is sourced from fish ingredients such as Salmon and Menhaden Fish. Fish-based proteins such as Salmon are the preferred source and can provide complete amino acid coverage. This protein content will be sufficient for the average dog. However, more active dogs may require additional protein. Some of this protein is from the legumes present. Plant-based protein such as this is considered inferior to animal-based proteins.

Fat Content Analysis

Dogs use fat as a concentrated energy source. In addition, fats also play a role in development and maintenance. As the chart above displays, a minimum of 33% of Nutri Source – Seafood Select calories are derived from fat. Please note that this is the minimum amount of fat as calculated by the guaranteed analysis. In reality, this value of fat is likely to be a lot higher. This is above average for a Dry Dog Food.

The fat present appears to be from the fish ingredients such as Salmon and Menhaden Fish. Meat and fish-based fats are the natural sources of fat in a dog’s diet. This level of fat is sufficient to satisfy the energy needs of the vast majority of dogs. Unfortunately, fish meal such as Menhaden Fish Meal has had most of its beneficial oils removed. Despite this, the overall level of the Omega Fatty Acids is satisfactory.

Calorie Density

Calorie Density is essential to understand as it determines the portion size of food your dog will require per day or meal. Calorie Density is commonly measured in calories per kg or per cup.
Dog food formulas with high-calorie densities can be more cost efficient to purchase while recipes with lower calorie density can be advantageous to dogs attempting weight loss or who are relatively inactive.

Overall Nutri Source – Seafood Select contains an average of 3890 kcal/kg or 451 kcal/cup

Disclaimer

Once again please note that the values in this section are calculated using the products guaranteed analysis. The guaranteed analysis only lists the minimum and maximum values and as a consequence, these can sometimes be an inaccurate representation. As a rule of thumb, most dog foods will contain slightly more protein and considerably more fat than their guaranteed analysis. This will have the knock-on effect of reducing the relative amount of carbohydrates present. However also note that every dog food is different and some will be considerably closer to the guaranteed analysis than others.

Guaranteed Analysis – Nutri Source – Seafood Select

Pet foods in the United States are legally required by the AAFCO to have a guaranteed analysis on their packaging. A guaranteed analysis must display certain nutritional information. This is similar to how nutritional values are now commonly displayed on food for human consumption. The information that must be displayed includes Crude Protein, Crude Fat, Crude Fiber, and Moisture. Some guaranteed analysis will contain additional information. The guaranteed analysis for this product is listed below.

  • Crude Protein (Min) – 25.00%
  • Crude Fat (Min) – 15.00%
  • Crude Fiber (Max) – 7.00%
  • Moisture (Max) – 10.00%
  • Omega 6 Fatty Acids (Min) – 2.0%
  • Omega 3 Fatty Acids (Min) – 0.4%

 

Ingredient Analysis

The ingredients of pet food are disclosed on the packaging of the product as a list in descending order. Therefore the ingredients at the start of the list make up the bulk of the pet foods content. As a consequence, the quality of these primary ingredients is the most significant factor in determining the quality of pet food.

However, ingredients listed further down the ingredient list should not be ignored, especially if they could have adverse or harmful effects on a pet.

In-Depth Meat/Fish Ingredient Review

The meat and fish ingredients of dog food are without a doubt the most important. They are critical as they provide the majority of the protein and fat that dogs desperately need. Also, these ingredients would have made up the bulk of dogs ancestors diet. Therefore, the quality of a dog food formulas meat and fish ingredients is crucial. Nutri Source – Seafood Select contains two sources of meat or fish.

The primary fish source present is Salmon. Salmon is considered a high-quality source of protein. Salmons most abundant minerals are Vitamin B12 and Selenium. Just like other fish, Salmon contains a large quantity of the Omega 3 Fatty Acids. Unfortunately just as with meat, Salmon contains a high concentration of water. Much of this water is evaporated during the cooking process leaving a lesser proportion of Salmon. However given that Salmon is the first listed ingredient, its quantity after cooking is likely to be relatively high.

Another fish source present is Menhaden Fish Meal. Menhaden Fish Meal is considered an average-quality source of fish. Menhaden Fish are small oily fish that are not fit for human consumption. The oil is removed from these fish and the leftover flesh is turned into fish meal. This fish meal is high in protein. Unfortunately, as most of the oil has been removed Menhaden Fish Meal is not high in the beneficial Omega Fatty Acids like other fish.

In-Depth None-Meat Ingredient Review

Peas are a member of the legume family of vegetables. Legumes are famous for having a relatively high amount of protein for a vegetable. Legumes also contain a high amount of fiber, which is important for healthy digestion. Pet foods often use legumes as a replacement for in grain-free pet food. Protein from vegetables such as legumes should not be a replacement for protein from meat. Instead, it should act as an additional protein source.

Pea Flour is a by-product of Peas. Pea Flour is considered a low-quality ingredient. Pea Flour is similar to Pea Protein but also contains a considerable proportion of carbohydrates. Pea Flour is often used as a cheap filler and the carbohydrates and plant-based protein it provides are inferior to the nutrition other whole ingredients can provide. Pea Flour is an ingredient commonly used in a technique called Ingredient Splitting.

Alfalfa is a flowering plant that is closely related to Peas and other legumes. Alfalfa has a long history of use in livestock feed and as a supplement for humans. It has a similar proportion of protein to other legumes which means it can contribute to a minor sum if there is a sufficient quantity used. Alfalfa’s greatest strength is the vast range of vitamins and minerals it provides including Vitamin K, Vitamin C, Beta Carotene, Potassium, and Calcium.

Flaxseed is a beneficial ingredient that is commonplace in higher quality dog food. Flaxseed contains high levels of the Omega 3 and 6 Fatty Acids which provide a range of health benefits such as healthier skin and fur and improved cognitive function. Also, Flaxseed contains high levels of protein for a plant-based ingredient. Finally, Flaxseed provides Lignans which can help reduce inflammation and cholesterol.

A noteworthy ingredient present in this formula is Tomato Pomace. Tomato Pomace is made up of tomato skin, seeds, and pulp. Its most beneficial feature is that it contains very high levels of soluble fiber which can aid and regulate digestion. Those high levels of fiber are the primary motivation behind this ingredients inclusion in most formulas as Tomato Pomace has little nutritional value.

Sunflower Oil is one of a number of oils commonly added to pet food. Sunflower Oil contains high amounts of Omega 6 Fatty Acids. However, it does not provide any of the Omega 3 Fatty Acids which are often considered the more beneficial of the two. For that reason, Sunflower Oil is considered by many to be a less desirable addition than other oils such as Salmon and Canola Oil.
