Hill’s Prescription Diet k/d Canine Renal Health

Hill's Prescription Diet kd Canine Renal Health

Hill’s Prescription Diet k/d Canine Renal Health is a dog food specially formulated for the nutritional management of dogs with renal disease.

Kidneys are vital because they eliminate waste substances from the blood, and preserve the normal balance of fluid and minerals within the body. Once kidney injury occurs, the consequences are usually permanent.

Renal disease may develop due to other diseases or changes in health, breed/hereditary predispositions and even nutritional factors. Clinical signs of renal disease don’t usually appear until more than 2/3 of kidney function are lost.

This Hill’s formula is clinically proven to prolong and improve quality of life in dogs with renal disease.

There is no cure for chronic renal disease. However it can be successfully managed, and nutritional treatment is a significant part of that therapy.

Nutrient Analysis

Hill’s Prescription Diet k/d Canine Renal Health already gives information about dry matter basis.

Dry Matter Basis
Protein 14.3 %
Fat 19.5 %
Fiber 2.4 %
Carbohydrates 59.5 % (EV)

(EV: estimated value)

Animal feeding tests using AAFCO procedures substantiate that Prescription Diet k/d Canine Renal Health provides complete and balanced nutrition for maintenance of adult dogs.

For kidney disease it is recommended a diet with moderate to severe protein restriction. Restriction of dietary protein has been demonstrated to slow the rate of progression of renal damage. Thus this recipe just have 14.3 % of protein. In order to compensate for this protein drop, the concentration of fat is increased – 19.5 %.

Detail Ingredient Analysis

Protein: Eggs are a good source of inexpensive and good quality protein, fat and various minerals and micronutrients.

Corn Gluten Meal is a by-product of corn processing and can be used to increase the protein levels of dog foods as an alternative to meat-proteins. Corn gluten protein is not as easy for dogs to deal and as a result it can lead to health problems like skin problems and hyperactivity.

Carbohydrates: Brewers Rice (broken rice) is an easily digested carbohydrate that contains fiber. Rice fragments contain fewer nutrients than a whole grain of rice. Thus, brewers rice does not contain a large amount of nutritional value but it is not harmful for dogs unless they are allergic.

Fiber: Powdered Cellulose can come from the cell walls of all plants. It is almost indigestible to dogs. It contributes to an easy digestion process and firmer stools. However, it can be a controversial ingredient. Pure cellulose is a white, fragrance-free powder usually made from paper or wood pulp.

Dried Beet Pulp is an insoluble fiber source. It adds bulk and moisture to animal stools and provides energy to intestinal flora improving colon health. However, there have been several reported problems concerning the use of beet pulp in animal foods. For example potential swelling in the stomach, palatability, and plugging of the intestinal villus. Few of these studies refer to the feeding of beet pulp to horses and not to dogs. So, I believe that in proper amounts beet pulp is a good source of fiber for dogs.

Fat and oil: Pork fat is a named source of fat. It is highly palatable and rich in omega 6 fatty acids.

Flaxseed Ground is one of the richest sources of the essential omega 6 and omega 3 fatty acids. It is also a good source of essential amino acids and contains all the essential vitamins and minerals required by dogs. Yet, flaxseed contains phytoestrogens that are components able to mimic estrogens (reproductive hormones) in the body. Thus it can interfere with reproductive cycle in dogs.

Flavors: Natural Flavors can denote to any extract from adding flavor foods and it could refer to anything from herbs or meat meals to more questionable ingredients like meat by products. In dry dog foods, natural flavorings occasionally refers to a combination of fresh meat and oils which is sprayed on to the food in the final stages of manufacturing.

Chicken Liver Flavor represents a named natural flavor. So you know the origin of this flavor – chicken liver. It has a poor nutritional value but dogs love liver taste.

Supplements: Water soluble vitamins are supplemented in this dog food. Animals with renal failure have an increase in their urine output, and consequently a greater excretion of water soluble vitamins (B Vitamins and Vitamin C). Loss of these vitamins may contribute to the anorexia associated with renal disease.

Non chelated minerals are difficult for a dog to absorb. So these minerals can pass through a dog’s digestive tract and be wasted in the stools.

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

Final Comment

Based on the ingredients included in Hill’s Prescription Diet k/d Canine Renal Health we give a 3.2 stars score.

Evaluating by its ingredients alone Hill’s Prescription Diet k/d Canine Renal Health seems to be a recommended dry dog food.

A clinical study preformed in dogs with naturally occurring chronic renal failure concluded that feeding Hill’s Prescription Diet k/d can delay the onset of clinical signs, prolong survival time for dogs with chronic renal failure, improve quality of life and delay progression of renal disease.

Supplementation with other foods or treats is pointless and may decrease the success of the nutritional treatment.
