Detail Ingredient Analysis

Protein: Chicken protein is included here as chicken meal – a concentrated form of chicken protein. This meat protein is very popular in dog foods. Chicken is highly palatable, low-priced and provides an excellent source of protein.

Dried egg product is a source of high quality protein and fatty acids. Eggs represent a complete protein source providing all the essential amino acids. The fatty acid profile includes arachidonic acid, and omega 6 fatty acids connected with healthy skin and coat.

Corn gluten meal is a by-product of corn processing. It is used to raise protein levels of dog foods, It is used as an alternative to more costly meat proteins. However, gluten protein is not easy for dogs to digest and it can lead to health issues like skin problems and hyperactivity.

Carbohydrates: Brewer’s rice corresponds to the small fragments of rice kernels. The perfect kernels go to human consumption and the broken kernels are included in dog food. This processed rice product is missing many of the nutrients included in whole ground rice.

Corn is a low grade, controversial ingredient. It is used in dry dog foods as a substitute to grains like rice, oats and barley. Corn can be hard for dogs to digest and can lead to food intolerance or allergies.

Fiber: Powdered cellulose is a fiber source in dry dog foods. It has the lowest food value of any kind of fiber. It is a purified, mechanically disintegrated cellulose prepared by processing alpha cellulose obtained as a pulp from fibrous plant materials.

Fat and oil: Chicken fat is a high quality source of essential fatty acids and energy. It is rich in linoleic acid (source of omega 6 fatty acids), which helps promote healthy skin and coat.

Generally, fish oil comes from oily fish like tuna, sardines, salmon and mackerel. It contains abundant essential omega 3 and omega 6 oils which have lots of health benefits. Fish oils can aid in the prevention of some health conditions including joint problems, skin conditions, cardiovascular disease and even cancer. However, there is no mention to the fish names used to produce this oil.

Flavors: Natural flavors is an ambiguous term. It can be any extract from any food. It could refer to anything from meat meals to more debatable ingredients like digest. Commonly, natural flavors refers to a combination of fresh meat and oils which is scattered on to the food in the final stages of manufacturing.

Supplements: Rosemary extract is a powerful antioxidant which is able to slow down the oxidization process. So it is known as an excellent and natural preservative that is also know to help protect against cancer.

Salt (sodium chloride) is usually added to dog foods as a flavor enhancer. Dogs appreciate the taste of salt. When added in appropriate amounts salt does not cause any problems. However, excessive salt has the same health consequences for dogs as for us and should be avoided.

Taurine is an amino acid. Taurine supplementation can help in the treatment of heart problems.

This dog food contains chelated minerals that are easier to absorb. Chelated minerals are usually found in better dog foods.

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.
