Life 4K9 Dog Food receives the Advisor’s mid-tier rating of 3.5 stars.
The Life 4K9 product line includes two dry dog foods.
However, since we’re unable to locate AAFCO nutritional adequacy statements for these dog foods on the company’s website, it’s impossible for us to report specific life stage recommendations for these recipes.
The following is a list of recipes available at the time of this review.
- Life 4K9 Lamb and Barley
- Life 4K9 Chicken and Barley
Life 4K9 Chicken and Barley was selected to represent both products in the line for this review.

The first ingredient in this dog food is chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.2
Chicken is naturally rich in the ten 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 barley. Barley is a starchy carbohydrate supplying fiber and other healthy nutrients. Unlike grains with a higher glycemic index, barley can help support more stable blood sugar levels.
The fourth ingredient is oats. Oats are rich in B-vitamins, minerals and dietary fiber.
The fifth ingredient is whitefish meal, another protein-rich meat concentrate.
Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.2
The sixth ingredient is dicalcium phosphate, likely used here as a dietary calcium supplement.
The seventh ingredient is olive oil. Olive oil contains oleic acid, a healthy monounsaturated fat. It’s also rich in natural antioxidants and carotenoids.
The eighth ingredient is tomato pomace. Tomato pomace is a controversial ingredient, a by-product remaining after processing tomatoes into juice, soup and ketchup.
Many praise tomato pomace for its high fiber and nutrient content, while others scorn it as an inexpensive pet food filler.
Just the same, there’s probably not enough tomato pomace here to make much of a difference.
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 this product.
With five notable exceptions…
First, this recipe contains vegetable oil, a generic oil of unknown origin. The ratio of omega-6 to omega-3 fats in any oil is nutritionally critical and can vary significantly (depending on the source).
Without knowing more, it’s impossible to judge the quality of an item so vaguely described. However, compared to a named animal fat, a generic vegetable oil cannot be considered a quality ingredient.
Next, flaxseed meal is one of the best plant-based sources of healthy omega-3 fatty acids. Flax meal is particularly rich in soluble fiber.
However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.
In addition, we note that this product contains avocado oil. Avocado products can be somewhat controversial.
Supporters claim the ingredient to be nutrient rich and beneficial to a dog’s skin and coat — while others worry over what are mostly unsubstantiated concerns over potential toxicity.
These fears appear to originate from a 1984 study in which goats (not dogs) consumed the leaves (not the fruit) of the Guatemalan (not the Mexican) avocado and became ill.4
Based upon our own review of the literature, it is our opinion that the anxiety over avocado ingredients in dog food appears to be unjustified.
Next, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
And lastly, this food also contains chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
Life 4K9 Dog Food
The Bottom Line
Judging by its ingredients alone, Life 4K9 Dog Food looks like an above-average dry product.
But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.
As a group, the brand features an average protein content of 24% and a mean fat level of 10%. Together, these figures suggest a carbohydrate content of 58% for the overall product line.
And a fat-to-protein ratio of about 43%.
Below-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the flaxseed meal, this looks like the profile of a kibble containing a modest amount of meat.
Life 4K9 Dog Food is a plant-based kibble using a modest amount of chicken or lamb meals as its main sources of animal protein, thus earning the brand 3.5 stars.
