Ingredients Analysis
The first ingredient is deboned chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1
Chicken is naturally rich in the 10 essential amino acids required by a dog to sustain life.
The second ingredient is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The third ingredient is lentils. Lentils are a quality source of carbohydrates. Plus (like all legumes) they’re rich in natural fiber.
However, lentils contain about 25% protein, a factor that must be considered when judging the actual meat content of this dog food.
The fourth ingredient is dried sweet potato, a dehydrated item usually made from the by-products of potato processing. In most cases, dried sweet potato can contain about 10% dry matter protein which can have a slight affect on our estimate of the total meat content of this recipe.
The fifth ingredient is yellow peas. Peas are a quality source of carbohydrates. And like all legumes, they’re rich in natural fiber.
However, peas contain about 25% protein, a factor that must be considered when judging the meat content of this dog food.
The sixth ingredient is chicken fat. Chicken fat is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.
The seventh ingredient is pea fiber, a mixture of both soluble and insoluble dietary fiber derived from pea hulls. Aside from the usual benefits of fiber, this agricultural by-product provides no other nutritional value to a dog.
The eighth ingredient is natural chicken flavor. Natural flavors doesn’t give us much information about the particular ingredients included in this dog food for flavoring purposes.
We’re pleased that the flavorings used are natural, but more details are required to give any further information about these natural flavoring ingredients. Flavorings are used to make the foods more appealing and tasty for our dogs.
The ninth ingredient is calcium carbonate, likely used here as a dietary mineral supplement.
From here the list goes on to include a number of other items. But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of the product.
This recipe has four notable exceptions.
First salmon oil. Salmon oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids.
Depending on its level of freshness and purity, salmon oil should be considered a commendable addition.
Next, chicory root. Chicory is rich in inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.
Not only is inulin a natural source of soluble dietary fiber, it’s also a used to promote the growth of healthy bacteria in a dog’s digestive tract.
We note the inclusion of dried fermentation products in this recipe. Fermentation products are typically added as probiotics to aid with digestion.
This food also contains chelated minerals, that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
Nutrient Analysis
Based on its ingredients alone, Nulo MedalSeries Limited Ingredient Diet Grain-Free Puppy and Adult Chicken looks like an above-average dry product.
The dashboard displays a dry matter protein reading of 33.5%, a fat level of 19.3% and an estimated carbohydrate level of 33.8%.
As a group, the brand features a protein content of 34.7% and a mean fat level of 17.8%. Together, these figures suggest a carbohydrate content of 33.2% for the overall product line, alongside a fat-to-protein ratio of 51%.
This means this Nulo product line contains above-average protein, below-average carbohydrate and near-average fat when compared to typical dry dog food.
