Carbohydrates 50.5 % (EV)

(EV: estimated value)

On a dry matter basis, this food is formulated to assemble the nutritional levels established by the AAFCO.

This food includes reasonable amounts of protein and fat, with a blend of animal and plant proteins sources. It has a relatively high percentage of carbohydrates.

Detail Ingredient Analysis

Protein: Dried egg product is dried egg that is free of shells. It is easy to digest and have an exceptionally high biological value. Eggs also represent a good source of antioxidants, such as lutein.

Chicken by-product meal is less expensive and less digestible than chicken fresh meat. Its nutritional value is not consistent because by-products consist of any parts of the animal other than meat. They include the waste of meat processing not intended for human consumption.
Named by-product meals, like chicken by-product meal, may not be considered the highest quality ingredients but they can be considered allowable.

Corn gluten meal is used as a low-cost protein source for dog foods. Some dogs may develop an allergy to corn after eating corn gluten meal for an extended amount of time. It is a considered as a low-grade protein booster in dog foods.

Carbohydrates: Corn makes dog foods less expensive to produce. However, corn does save money for manufacturers but it also makes dog food more reasonably priced for dog owners. Whole grain corn is commonly used as a carbohydrate source for energy and can also provide natural sources of vitamins and fiber. Some dogs may be allergic to corn.

Fiber: Brewers rice is made from small milled fragments of rice kernels. As a processed rice product it is missing many of the nutrients contained in whole ground rice and brown rice.

The most common source for powered cellulose is dried wood. It is cleaned, processed into a fine powder and used to add bulk and consistency to dog foods. I would consider this ingredient not appropriate for inclusion in dog foods.

Dried beet pulp is a controversial ingredient. It is considered by some as an inexpensive filler. However, dried beet pulp is a natural, fermentable source of fiber. It also presents exceptional intestinal health and blood sugar benefits. Thus I believe that the inclusion of beet pulp in rational amounts in dog foods is entirely acceptable.

Fat and oil: Soya oil is free from soya proteins and therefore does not disturb the gastrointestinal tract of dogs with soya intolerance. Soybean oil is cholesterol free but it is generally regarded as a lower-grade option.

Pork fat is a product from rendering pig meat. It can add considerable flavor to dog food. This ingredient is rich in linoleic acid an omega-6 fatty acid essential for life.

Flavors: Natural flavor in dog foods sometimes refers to a mixture of fresh meat and oils which is sprayed on to the food in the final stages of manufacturing. But it is considered as a controversial ingredient because it is an ambiguous origin.

Chicken liver flavor is a named source of flavor. Adding this ingredient to dog food is entirely acceptable.

This dog food does not contain any vegetables or fruits. Vitamins and minerals are added as supplements to this food.

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

Hi! I’m Dora Mancha, DVM. I am graduated for the Veterinary Medicine Faculty of Lisbon (2009). My degree is recognized by the American Veterinary Medical Association (AVMA). I completed my degree in Veterinary Medicine in July, 2009. Over the first years as a veterinarian my work was closely related to the animal health field. I have gained some average experience having worked in Barcelona University (UAB) Equine Hospital and by working with veterinarians in Portugal. In addition, in 2009 – 2010 I was in Madrid at the University Alfonso X el Sábio doing an internship in the equine service. I am also very interested in small animal medicine and surgery. In fact I worked in several small animals clinics in Portugal improving my knowledge about small animal behavior and health. Dogs always have been present in my life, since I was a child. At the present moment I have four dogs a Labrador, a Epagnheul Breton, a Whippet and a mixed breed dog.
