The first ingredient in this dog food is lamb. Although it is a quality item, raw lamb 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 second ingredient is barley. Barley is a starchy carbohydrate supplying fiber and other healthy nutrients. However, aside from its energy content, this cereal grain is of only modest nutritional value to a dog.
The third ingredient is oatmeal, a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in B-vitamins, dietary fiber and can be (depending upon its level of purity) gluten-free.
The fourth ingredient is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The fifth ingredient includes 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 dried egg, a dehydrated powder made from shell-free eggs. Eggs are easy to digest and have an exceptionally high biological value.
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 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 ninth ingredient is millet, a gluten-free grain harvested from certain seed grasses. Millet is hypoallergenic and naturally rich in B-vitamins and fiber as well as other essential minerals.
After the natural flavor, we find 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.
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 ten notable exceptions…
First, we find brewers yeast, which can be a controversial item. Although it’s a by-product of the beer making process, this ingredient is rich in minerals and other healthy nutrients.
Fans believe yeast repels fleas and supports the immune system.
Critics argue yeast ingredients can be linked to allergies. This may be true, but (like all allergies) only if your particular dog is allergic to the yeast itself.
In addition, a vocal minority insists yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is a claim we’ve not been able to scientifically verify.
In any case, unless your dog is specifically allergic to it, yeast can still be considered a nutritious additive.
What’s more noteworthy here is that brewers yeast contains about 48% protein, a factor that must be considered when judging the actual meat content of this dog food.
Next, this food includes pea protein, what remains of a pea after removing the starchy part of the vegetable.
Even though it contains over 80% protein, this ingredient would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the meat content of this dog food.
In addition, this recipe contains alfalfa meal. Although alfalfa meal is high in plant protein (about 18%) and fiber (25%), this hay-family item is more commonly associated with horse feeds.
Next, we note the inclusion of quinoa. Quinoa (pronounced keen-wah) is not a true cereal grain but a plant prized for its gluten-free seeds.
Compared to most other grain-type ingredients, it is high in protein (about 12-18%), dietary fiber and other healthy nutrients.
This food also contains chia seed, an edible seed nutritionally similar to flax or sesame. Provided they’re first ground into a meal, chia seeds are rich in both omega-3 fatty acids as well as dietary fiber.
However, chia seeds contain about 17% protein, a factor that must be considered when judging the meat content of this dog food.
Next, caramel is a natural coloring agent made by caramelizing carbohydrates. It’s used by pet food manufacturers to impart a golden brown tint to the finished product.
However, the concentrated version of this ingredient commonly known as caramel coloring has been more recently considered controversial and found to cause cancer in laboratory animals.1
In any case, even though caramel is considered safe by the FDA, we’re always disappointed to find any added coloring in a pet food.
That’s because coloring is used to make the product more appealing to humans — not your dog. After all, do you really think your dog cares what color his food is?
In addition, coconut oil is a natural oil rich in medium-chain fatty acids.
Medium-chain triglycerides have been shown to improve cognitive function in older dogs.2
Because of its proven safety3 as well as its potential to help in the treatment of canine cognitive dysfunction syndrome (CDS) and chronic skin disorders, MCT can be considered a positive addition to this recipe.
Next, chicory root 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 prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.
Next, garlic can be a controversial item. Although many favor the ingredient for its claimed health benefits, garlic has been linked to Heinz body anemia in dogs.4
So, one must weigh the potential benefits of feeding garlic against its proven tendency to cause subclinical damage to the red blood cells of the animal.
And lastly, this food 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.
Blue Buffalo Earth’s Essentials Dog Food The Bottom Line
Judging by its ingredients alone, Blue Buffalo Earth’s Essentials 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.
The dashboard displays a dry matter protein reading of 27%, a fat level of 16% and estimated carbohydrates of about 50%.
As a group, the brand features an average protein content of 27% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 50% for the overall product line.
And a fat-to-protein ratio of about 58%.
Near-average protein. Near-average fat. And near-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the peas, flaxseed, brewers yeast, pea protein, alfalfa meal, quinoa and chia seed, this looks like the profile of a kibble containing a moderate amount of meat.
Blue Buffalo Earth’s Essentials is a plant-based dry dog food using a moderate amount of named meats as its main sources of animal protein, thus earning the brand 3.5 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.
