The first ingredient in this dog food is salmon meal. Because it is considered a meat concentrate, fish meal contains almost 300% more protein than fresh fish itself.
Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.1
The second 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 third ingredient is 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 fourth ingredient is pea starch, a paste-like carbohydrate extract probably used here as a gel-like binder for making kibble.
The fifth ingredient is salmon. Although it is rich in omega-3 fatty acids, raw salmon contains about 80% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.
After processing, this item would probably account for a smaller part of the total content of the finished product.
The sixth ingredient is salmon oil. Salmon oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to dogs and humans.
Depending on its level of freshness and purity, salmon oil should be considered a commendable addition.
The seventh ingredient is flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also 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.
The eighth ingredient is liquid egg product, an aqueous form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.
In any case, eggs are easy to digest and have an exceptionally high biological value.
The next items include six nutrient-rich vegetables and fruit…
- Bok choy
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 three notable exceptions…
First, this recipe contains fructooligosaccharide, an alternative sweetener3 probably used here as a prebiotic. Prebiotics function to support the growth of healthy bacteria in the large intestine.
Next, we note the inclusion of dried fermentation products in this recipe. Fermentation products are typically added to provide enzymes to aid the animal 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.
Horizon Pulsar Dog Food
The Bottom Line
Judging by its ingredients alone, Horizon Pulsar Dog Food looks like an above-average kibble.
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 31% and a mean fat level of 17%. Together, these figures suggest a carbohydrate content of 45% for the overall product line.
And a fat-to-protein ratio of about 54%.
Above-average protein. Near-average fat. And below-average carbs when compared to a typical dry dog food.
However, when you consider the protein-boosting effects of the lentils, peas and flaxseed, this looks like the profile of a kibble containing a moderate amount of meat.
Horizon Pulsar Dog Food is a legume-based kibble using a moderate amount of fish or chicken meals as its main sources of animal protein, thus earning the brand 4.5 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content.
