Detail Ingredient Analysis

Protein: Chicken and Chicken Meal are well-liked meat protein sources found in dog foods. It is highly palatable, inexpensive and provides an outstanding source of protein. It also provides essential amino acids, fatty acids, vitamins and certain minerals.

Gluten is a protein that comes from wheat and other related grains, like corn. This dog food contains Corn Gluten Meal and Wheat Gluten. These ingredients are included in dry dog biscuits to prevent them from breaking. However, because gluten is a protein source, it is sometimes used to increase protein levels in the nutritional label.

In addition, corn gluten protein is not always easy for dogs to digest and as a result it can lead to health issues like skin and digestive problems (e.g. pruritus, diarrhea and vomit).

Carbohydrates: Whole Grain Wheat is used to hold kibbles together. It is also a grain used as a carbohydrate source in dry dog foods. It provides energy for daily activity. However, it is frequently associated with food intolerance in dogs which makes it a controversial ingredient. Wheat intolerance can lead to various health problems most commonly affecting the skin, coat and digestive system.

Brown Rice, as long as, it is well cooked, it is easily digested by dogs. It contains lots of natural nutrients including B vitamins, iron, manganese, selenium, magnesium and omega 3 fatty acids. It is also a good source of fiber which is important for intestinal health.

Cracked Pearled Barley is barley that has been dehulled and has the bran removed. It adds additional protein, complex carbohydrates, fiber and vitamins and minerals to the diet.

A good quality whole grain corn is a nutritious carbohydrate source. However, it is considered to be a controversial ingredient because sometimes corn is harder to digest and is therefore can lead to food intolerance or allergies.

Whole Grain Sorghum is used in dog foods as a low-cost alternative to traditional grains. Sorghum grain has a similar nutrient profile to corn. Unlike corn though, sorghum is gluten free so it is often recommended for dogs that are predisposed to food intolerance.

Fiber: Oat Groats are cleaned oats with the hulls removed. This ingredient is a natural source of fiber, iron, manganese, zinc and B vitamins as well as essential fatty acids and antioxidants. It includes almost a complete list of the essential amino acids necessary to a complete and balanced diet. Oat Fiber is a good ingredient to support weight management and bowl function.

Powdered Cellulose is mainly an insoluble fiber. In this food it is likely used as part of the fiber blend to help prevent plaque and tartar. However, it can induce some gastrointestinal problems when used in inappropriate amounts. Additional its official definition is also a source of controversy: “purified, mechanically disintegrated cellulose prepared by processing alpha cellulose obtained as pulp from fibrous plant materials,” the more simple definition would be “sawdust.”

Soybean mill run is composed of hulls from soybeans and soybeans portions that stick to them while they’re being milled. In this oral care food this ingredient is part of the fiber blend that is used to keep the dog’s teeth clean.

Fat and oil: Chicken Fat is a source of essential fatty acids and energy, chicken fat is also rich in Omega 6 fatty acids, which helps promote healthy skin and coat.

Soybean Oil is cholesterol free. It contains unsaturated fat and essential fatty acids, and Vitamin E. It promotes healthy skin and coat. However, it contains more saturated fat than most other vegetable oils it is generally regarded as a poor option. Soya oil is free from soya proteins and therefore does not disturb dogs with soya intolerance.

Generally Fish Oil comes from the processing of oily fish like tuna, sardines, salmon and mackerel. It contains lots of essential omega 3 and omega 6 fatty acids which have numerous health benefits. They are beneficial to some health conditions including joint problems, skin conditions, cardiovascular disease and cancer. However we don’t know the precise source of the fish oil used in this dog food.

Fruits and vegetables: This dog food includes dried fruits and veggies – Dried Apples, Dried Broccoli, Dried Carrots, Dried Cranberries, Dried Peas. These ingredients are excellent sources of vitamins, minerals, fiber and antioxidants.

Dried Peas are difficult to digest for some dogs, thus they can cause some intestinal problems such as diarrhea, vomit and flatulence.

Flavors: Chicken Liver Flavor and Pork Liver Flavor since these are named sources, it looks all right. However, the food also contains Natural Flavors. Natural flavors in dog food could be almost anything approved by the FDA as GRAS (generally recognized as safe). It is regularly monosodium glutamate (MSG) which is added to human foods for flavor and color.

Supplements:  Taurine is an amino acid important for the heart. Beta-carotene is a carotenoid from plants that forms vitamin A in the body. It’s fundamental for vision, immunity, and other health benefits.

The minerals included in the ingredient list do not appear to be chelated. And that can make them more difficult to absorb.

This food does not contain dyes, sweeteners or artificial preservatives.

Why was the Dog Food Selector created?

Each dog has unique needs... The approach "one food for all dogs" isn't the more suitable. Dogs have different sizes, different life stages, unique breed characteristics, health conditions and a few other factors... Choosing the right food for your dog may help him or her life a longer and healthier life! We exist to make that task easier for you.

How does the Dog Food Selector work?

It's quite simple... It's a 1-2 step process. You just have to fill in the form with your dog's characteristics, like gender, age, size, activity, health conditions and a few other important data and click "search". Then, you'll see a list of dog foods with the highest review score. If you wish you can see all the detailed review of each individual dog food.
