Blue Buffalo Dog Food Review

Ingredients Analysis

The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken contains up to 73% 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 chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.

The third ingredient is brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.

The next 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 fifth item 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 next ingredient is pea starch, a paste-like, gluten-free carbohydrate extract probably used here as a binder for making kibble. Aside from its energy content (calories), pea starch is of only modest nutritional value to a dog.

The seventh ingredient is flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided theyve 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 chicken fat. This item 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 doesnt sound very appetizing, chicken fat is actually a quality ingredient.

The ninth ingredient is tomato pomace which can be 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, theres probably not enough tomato pomace here to make much of a difference.

After the natural flavor, we find peas. Peas are a quality source of carbohydrates. And like all legumes, theyre 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.

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 Blue Buffalo Life Protection product.

With nine notable exceptions

First, 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.

Next, we find 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.

We also note the use of alfalfa nutrient concentrate, a vitamin and mineral-rich extract made from alfalfa.

Even though it contains over 50% protein, this ingredient would be expected to have a lower biological value than meat.

In addition, pea fiber is 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.

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.¹

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.

Additionally, dried yeast can be a controversial item. Dried yeast contains about 45% protein and is rich in 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.

Whats more, a vocal minority insists yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is something weve not been able to scientifically verify.

In any case, unless your dog is specifically allergic to it, we feel yeast should be considered a nutritious addition.

Blue Buffalo Life Protection Healthy Weight

This recipe also includes sodium selenite, a controversial form of the mineral selenium. Sodium selenite appears to be nutritionally inferior to the more natural source of selenium found in selenium yeast.

Taurine is also found in this product. Taurine is an important amino acid associated with the healthy function of heart muscle. Although taurine is not typically considered essential in canines, some dogs have been shown to be deficient in this critical nutrient.

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.

Nutrient Analysis

Based on its ingredients alone, Blue Buffalo Life Protection Dog Food looks like an above-average dry product.

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 26% and a mean fat level of 15%. Together, these figures suggest a carbohydrate content of 51% for the overall product line.

And a fat-to-protein ratio of about 57%.

Which means this Blue Buffalo product line contains

Near-average protein. Near-average fat. And above-average carbs when compared to other dry dog foods.

Even when you consider the protein-boosting effect of the flaxseed, pea products, alfalfa products and dried yeast, this looks like the profile of a kibble containing a moderate amount of meat.

Artificial Food Coloring Dyes

Blue Buffalo does not use any artificial food coloring dyes. According to our records, none of the 262 Blue Buffalo dog foods contain artificial food dyes.

Artificial food coloring dyes are unnecessary and potentially harmful ingredients. In general, we not not recommend feeding any pet foods that contain artificial dyes.

In 2010, the CSPI raised serious concerns regarding the safety of many artificial dyes. Most of the studies referenced by the CSPI involved prolonged or excessive consumption. Since most dogs consume the same foods throughout their lives, concerns raised by the CSPI are alarming to say the least.

Animal By-Products

According to our records, Blue Buffalo does not contain any animal by-products.

Animal by-products are basically the leftover parts of the the carcass after its been processed for meat. AAFCO defines by-products as the non-rendered, clean parts, other than meat, derived from slaughtered mammals.

Although by-products are still fairly nutritious ingredients, consumers have equated them with slaughterhouse waste. Therefore, most premium brands, including Blue Buffalo have decided to remove by-products and instead use named organ meats (beef liver, chicken gizzards).

Anonymous Meat Ingredients

Anonymous meats are animal-based ingredients which do not provide the source animal's name. These ingredients are controversial because they can come from almost any animal.

In addition, anonymous animal-based ingredients are very inexpensive and often the lowest quality meats that are still allowed to be used in pet food.

In general, we do not recommend feeding any products which contain anonymous meats. When in doubt, always contact the brand's customer service desk for further clarification.

Unfortunately, we've identified 1 anonymous meat ingredient used by Blue Buffalo.

Fish meal is defined by AAFCO as "the clean, dried, ground tissue of undecomposed whole fish or fish cutting, either or both, with or without the extraction of part of the oil." Since the specific type of fish is not mentioned, we cannot discuss any specific qualities of this ingredient. In general, anonymous ingredients are low quality inclusions when compared to ingredients such as tuna meal, salmon meal, catfish meal, etc.

The following recipes contain fish meal:

Controversial Ingredients

In most cases, ingredients which are given the controversial classification can be substituted with higher-quality alternatives. You should evaluate each controversial ingredient independently to see if there is truly a valid cause for concern.

Keep in mind, certain sacrifices often must be made to produce dog foods at a reasonable price. In general, the more expensive the product, the fewer controversial ingredients you'll find.

In our analysis, we've identified 6 controversial ingredients inside Blue Buffalo products. These controversial ingredients are listed below. Click on each ingredient for more information.

Dried tomato pomace is a by-product of tomato manufacturing. It's considered a controversial ingredient because many people believe it is an inexpensive low quality filler. However, tomato pomace provides a notable amount of dietary fiber, B vitamins, Lycopene, and vitamin A. Although it is a very inexpensive ingredient, it is not nutritionally empty.

The following recipes contain dried tomato pomace:

Powdered cellulose is produced from minuscule pieces of wood pulp and plant fibers. Other than its fiber content, powdered cellulose lacks any nutritional contribution.

The following recipes contain powdered cellulose:

Pea protein is produced by removing the starchy parts of peas. Pea protein is considered controversial because it provides a substantial plant based protein boost. This boost is undesirable because plant based protein is typically lower in biological value when compared to meat based proteins.

The following recipes contain pea protein:

Garlic in very small quantities can be an acceptable addition, however, garlic can also be toxic. Therefore many pet owners choose to completely avoid garlic.

The following recipes contain garlic:

Caramel color is a concentrated form of caramel, a natural food colorant. Caramel color has been linked to cancer in laboratory animals. Since our pets do not care about food color, caramel color is an unnecessary addition with possible health risks.

The following recipes contain caramel color:

Canola oil is a plant-derived oil from the seeds of canola plants. Although fat is an essential component of any diet, canola oil is controversial in pet food. Proponents claim that canola oil provides a better fat profile in comparison to other plant based oils. However, opponents claim that canola oil is typically produced with genetically modified rapeseed and that rapeseed oil has multiple adverse health affects.

The following recipes contain canola oil:

Potentially Harmful Ingredients

Harmful ingredients are those which have been linked to adverse health effects. In general, we do not recommend feeding any product which contains any harmful ingredients.

During our review, none of the Blue Buffalo ingredients analyzed were classified as harmful by our system. The absence of harmful ingredients is indicative of a relatively premium dog food brand.
