Zignature Pork Formula is a high-quality dry dog food. Its nutrient profile is above average and it provides significantly above average quantities of protein and fat. Despite being above average, we consider the carbohydrate proportion of this dog food to be a little above ideal.
The formula contains a range of high-quality ingredients and limits its meat ingredients to Pork. It also contains a range of Legumes, such as Peas, which are considered a high-quality source of carbohydrates. In addition, they provide fiber for healthy digestion. Sadly, the formula also contains by-products like Pea Flour.
Zignature’s Pork Formula contains a range of vegetables but it uses a single source of meat. This means it may be suitable for dogs that suffer from severe meat allergies or sensitivities.

A Full review of Pork Formula by Zignature
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.
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 31% of Zignature Pork 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 significantly below average for a Dry Dog Food.
The majority of this carbohydrate content appears to be from the vegetable content of this dog food. 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 and could be lower to better reflect a dog’s natural diet. That being said, they are from a reasonably high-quality source and this percentage is an overestimate.
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 30% of Zignature Pork 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 satisfactory proportion of protein and should be sufficient for the majority of dogs but may not be adequate for those who are overly active. It appears to be sourced from Pork ingredients. Meats like Pork are considered high-quality sources of protein and provide the full range of needed amino acids. Unfortunately, a minority of this protein level is from the vegetable content. Plant-based proteins are not as beneficial as animal-based protein.
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 39% of Zignature Pork 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 formula appears to be sourced from Pork ingredients present which are high-quality sources. This low estimate of fat content is sufficient to fulfill the energy needs of the majority of dogs but may not be sufficient for those who are extremely active. Unfortunately, the level of the Omega 3 Fatty Acids in this formula is disappointingly low. Those Fatty Acids can provide a range of health benefits.
Overall Zignature Pork Formula contains an average of 430 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 – Pork 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) – 31.00%
- Crude Fat (Min) – 18.00%
- Crude Fiber (Max) – 4.00%
- Moisture (Max) – 10.00%
- Calcium (Min) – 1.5%
- Phosphorus (Min) – 1.0%
- Omega 6 Fatty Acids (Min) – 3.0%
- Omega 3 Fatty Acids (Min) – 0.45%
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.

- Pea Flour
Dangerous / Harmful Ingredients
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 Pork Formula contains two sources of meat or fish.
The primary meat source present is Pork. Pork is considered a high-quality source of protein. Pork is particularly rich in thiamin and while it contains less iron than Beef or Lamb, its iron content is still significant. Unfortunately, just like Beef, Pork contains a high concentration of water. Much of this water is evaporated during the cooking process leaving a lesser proportion of Pork. However given that Pork is the first listed ingredient, its proportion will still be relatively high even after the cooking process.
The secondary meat source present is Pork Meal. Pork Meal is considered a high-quality source of protein. Meat Meal is a concentrated form of meat 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. Pork Meal will contain the same vitamins and minerals as Pork but in higher concentrations. This includes Thiamin and significant levels of the Iron.
In-Depth None-Meat Ingredient Review
Zignature Pork Formula contains Peas, and Garbanzo Beans (also known as 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.
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.
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.
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.
