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.

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. Nulo Freestyle Senior With Trout & Sweet Potatoes contains four sources of meat or fish.

The primary fish source present is Trout. Trout is considered a high-quality ingredient and source of protein. Trout has a range of benefits including very high levels of the Omega 3 Fatty Acids. Also, it is rich in Potassium, Vitamin B12 and Trout contains fewer contaminants such as Mercury than other fish. Unfortunately, just as with meat, Trout contains a high concentration of water. Much of this water is evaporated during the cooking process leaving a lesser proportion of Trout. However given that Trout is the primary ingredient, its proportion will be relatively high after the cooking process.

The secondary meat source present is Turkey Meal. Turkey 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. Turkey Meal will contain the same vitamins and minerals as Chicken but in higher concentrations. This includes the high levels of Niacin and Vitamin B6.

Another fish source present is Salmon Meal. Salmon 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. Salmon Meal will contain the same vitamins and minerals as Whitefish but in higher concentrations. This includes Vitamin B12 and Selenium.

Another meat source present is Turkey. Turkey is considered a high-quality source of protein. Some of the beneficial nutrients contained in Turkey include Vitamin B6 and Niacin. Unfortunately, Turkey does contain a high concentration of water. Much of this water is evaporated during the cooking process leaving a lesser proportion of Turkey. However given that Turkey is not one of the primary ingredients, its proportion will be relatively low after the cooking process.

In-Depth None-Meat Ingredient Review

Nulo Freestyle Senior With Trout & Sweet Potatoes contains Peas, Lentils, 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 essential 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.

Dried Chicory Root or Chicory Root Extract is an additive or supplement to dog food. It can provide a range of health benefits including soluble fiber to enable regular passage of stool, probiotics to aid and promote digestion, as well as potentially eliminate or prevent intestinal worms. While these benefits are not fully proven, there is strong evidence behind them. The proportion of Chicory Root used in most dog food recipes is tiny and does not contribute meaningful nutrition.
