The comparison table above shows that Nature's Logic dry dog foods provide significantly more protein than Diamond. More specifically, Nature's Logic guarantees at least 9.87% more protein. For wet dog foods, Diamond typically provides a little more protein (about 2.61% more).
Crude Fat Comparison For Dog Food
Fats are an absolutely vital component of a balanced canine diet. Not only do fats provide energy, but they also serve important roles in the normal development and function of your dog's body. For example, fats help dogs produce prostaglandins, which reduce inflammation among many other significant functions.
There is a relatively insignificant difference between the crude fat content of the two brands. With regards to wet dog food, Nature's Logic and Diamond also provide roughly the same amount of crude fat.
Both brands provide roughly the same amount of crude fiber. For wet dog foods, Nature's Logic provides more fiber (about 6.17% more).

Diamond Pet Food Ingredients vs. Nature's Logic Pet Food Ingredients
Here are some of the controversial ingredients used only by Diamond.
Meat Meal
Meat Meal
Meat meal is produced by cooking meat using a process called rendering. The rendering process dramatically reduces the natural moisture of meat and thereby results in a highly condensed protein source.
This ingredient is marked controversial because the source animal for the meat is not specified. These type of anonymous ingredient are typically very low quality and certainly inexpensive additions. The most unpleasing property of this ingredient is that the meat source can contain any mammal, even dogs & cats.
White Rice
White Rice
White rice is produced by removing the husk, germ, and bran of rice grains. Unlike brown rice which contains the bran and germ, white rice is nutritionally empty.
Ground Corn
Ground Corn
Ground corn is a cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in pet food.
Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.
Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.
In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked. In regards to the protein contribution, we must note that corn is a plant based protein which does not contain all of the necessary amino acids required by pets to sustain life. Therefore substituting corn for meat is an unsuitable substitution and actually degrades the overall protein quality of the product.
Finally, we'll discuss the claims about vitamins and minerals in corn. Although corn does provide many vitamins and minerals, it not necessarily an exceptional ingredient in this regards. There are many other ingredients which are more complete and biologically appropriate. Therefore the usage of corn as the primary ingredient in pet food should certainly warrant further questioning.
Brewers Rice
Brewers Rice
Brewer's rice is the small fragments of rice kernel that are separated from the larger kernels of milled rice. The fragments do not contain the same nutrition profile of the whole kernel and therefore brewer's rice is a lower quality grain. Brewer's rice is typically regarded as an inexpensive and low quality filler.
Tomato Pomace
Tomato Pomace
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.
Beef By-Products
Beef By-Products
By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, beef by-products contain nearly all parts of the beef which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.
Like other meat by-products, beef by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste. However, manufactures and many experts claim that animal by-products are unjustly criticized. Proponents state that "named" by-products, such as beef by-products, supply many important nutrients required by pets.
Corn Gluten Meal
Corn Gluten Meal
Corn gluten meal is a by-product from the production of various corn products (corn starch, corn syrup, etc). It's very high in protein (nearly 60% protein) and therefore can significant boost the protein content of the product. Because plant based proteins such as corn gluten meal are inferior to meat based proteins (lack many essential amino acids), they are not suitable substitutes.
Powdered Cellulose
Powdered Cellulose
Powdered cellulose is produced from minuscule pieces of wood pulp and plant fibers. Other than its fiber content, powdered cellulose lacks any nutritional contribution.
Chicken By-Product Meal
Chicken By-Product Meal
Chicken by-product meal is produced by cooking chicken by-products using a process called rendering. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, chicken by-products contain nearly all parts of chickens which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.
Like other meat by-products, chicken by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste. However, manufactures and many experts claim that animal by-products are unjustly criticized. Proponents state that "named" by-products, such as chicken by-products, supply many important nutrients required by pets.
Ground Whole Grain Corn
Ground Whole Grain Corn
Ground whole grain corn contains the entire corn kernel (the germ, bran, and endosperm). Corn is a cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in pet food.
Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.
Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.
In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked.

There are many other ingredients which are more complete and biologically appropriate. Therefore the usage of corn as the primary ingredient in pet food should certainly warrant further questioning.
Poultry By-Product Meal
Poultry By-Product Meal
Poultry by-product meal is a controversial ingredient because the source animal is not specified. Anonymous ingredients such as poultry by-product meal are typically low-quality ingredients in comparison to named protein by-product meals (e.g. chicken by-product meal, turkey by-product meal, duck by-product meal).
Canola Oil (Preserved With Mixed Tocopherols)
Canola Oil (Preserved With Mixed Tocopherols)
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.
We believe that certain pet food ingredients are linked to adverse health affects; these ingredients are classified as harmful.
Here are some of the harmful ingredients used only by Diamond.
Menadione Sodium Bisulfite
Menadione Sodium Bisulfite
Menadione sodium bisulfite is a synthetic version of vitamin K that has been linked to many health concerns. Research has suggested possible toxic reactions in liver cells and red blood cells among other serious problems. In fact, one large chemical supplier warns, "The substance is toxic to kidneys, lungs, liver, mucous membranes. Repeated or prolonged exposure to the substance can produce target organs damage."

The average cost-per-lb is heavily influenced by the varying amounts of moisture present in each brand's food products (wet vs. dry food, dry vs. freeze-dried food, etc). However, the average cost-per-kcal eliminates the influence of moisture. Therefore, the average cost-per-kcal is the better metric to consider.
