Review Summary

Zignature Catfish Formula is a high-quality dry dog food. Its nutrient profile is above average and it provides significantly above average quantities of protein. Despite being above average, we consider the carbohydrate proportion of this dog food to be above ideal and if lowered would better reflect a dog’s natural diet.

The formula contains high-quality ingredients and limits its fish ingredients to Catfish. It also contains a range of Legumes, such as Peas and Chickpeas, which are considered a high-quality source of carbohydrates. In addition, they provide fiber for healthy digestion. However, it also contains Pea Flour which is a by-product and a low-quality ingredient.

Zignature’s Catfish Formula contains a small range of vegetables and makes use of a single source of fish. This means it may be suitable for dogs that suffer from severe meat allergies or sensitivities.

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.

Zignature Catfish Formula 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 36% of Zignature Catfish Formula 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 below average for a Dry Dog Food.

The majority of this carbohydrate content appears to be from the vegetable ingredients of this dog food formula. Vegetables such as Peas and Chickpeas are considered high-quality sources of carbohydrates. These will be discussed in more detail later on. This is above what we would consider the ideal proportion of carbohydrates. Despite the carbohydrates being from a reasonably high-quality source and the percentage being an overestimate we would like to see this carbohydrate proportion be reduced to better reflect 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 32% of Zignature Catfish Formula 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 significantly above average for a Dry Dog Food.

This is a very satisfactory proportion of protein and should be sufficient for the vast majority of dogs including those who are more active. This protein appears to be sourced from the Catfish Ingredients present. Fish such as Catfish is considered a high-quality source of protein and can provide the full range of needed amino acids. Unfortunately, a minority of this protein is from the vegetable content of this formula. Plant-based proteins are not as beneficial as animal-based protein. An example of this could be Pea Flour.

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 32% of Zignature Catfish Formula 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 in this dog food recipe appears to be sourced from the Catfish ingredients which are high-quality sources. This low estimate of fat content is sufficient to fulfill the energy needs of the average dog but perhaps not those who are overly active. Fish-based fats such as Catfish provide high levels of the Omega 3 Fatty Acids which are known to provide a range of health benefits.

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 Zignature Catfish Formula contains an average of 410 Calories/Cup.


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 – Zignature – Catfish Formula

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) – 32.00%
  • Crude Fat (Min) – 14.00%
  • Crude Fiber (Max) – 3.00%
  • Moisture (Max) – 10.00%
  • Calcium (Min) – 1.6%
  • Phosphorus (Min) – 1.4%
  • Omega 6 Fatty Acids (Min) – 2.7%
  • Omega 3 Fatty Acids (Min) – 0.7%

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. Zignature Catfish  Formula contains two sources of meat or fish.

The primary fish source present is Catfish. Catfish is considered a high-quality source of protein. Vitamin D, Vitamin B12, and Phosphorus are just some of the minerals that Catfish contains in high quantities. Unfortunately, just as with meat, Catfish contains a high concentration of water. Much of this water is evaporated during the cooking process leaving a lesser proportion of Catfish. However given that Catfish is the first listed ingredient, its proportion will still be relatively high even after the cooking process.

The secondary fish source present is Catfish Meal. Catfish Meal is considered a high-quality source of protein. Fish Meal is a concentrated form of fish that has already had the majority of its moisture removed. This means that gram for gram it is much richer in protein and other nutrients. Catfish Meal will contain the same vitamins and minerals as Catfish but in higher concentrations. This includes the high levels of Vitamin D, Vitamin B12, and Phosphorus.

In-Depth None-Meat Ingredient Review

Zignature Catfish Formula contains Peas and Chickpeas. These are members 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 grains 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.

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.

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.

Salt, when added in moderation, is considered a beneficial ingredient. It enhances flavor, helps preserve the food and is important for maintaining healthy blood pressure and other bodily functions. However, some dogs, particularly those with cardiovascular problems may need to limit their consumption of Salt to avoid aggravating their health problems.
