Kidney Failure in Dogs and Cats

Nutrition should be considered as an integral part of treatment for animals in various stages of renal failure otherwise known as kidney failure.  It doesn't have to be a costly venture and sometimes alternative methods can go a long way to improve the health and well being of a pet in renal failure.
Avoiding stressors in their diet and providing key components can possibly extend the life of any pet in renal failure.  Simply put, kidneys process blood and eliminate waste and toxins, then eliminate through urination.
Speaking nutritionally, the two major stressors on kidneys is inadequate and improper protein and low moisture.
Commercial kibble diets are difficult on the kidneys due to the starch and low moisture.  Even some homemade diets can lack the proper nutrients required for kidney diets. 
A strong healthful diet is the first line of defense for the kidneys.  A low protein, low phosphorus and nutritious well balanced whole food diet that avoids hard to assymilate, synthetic vitamins and minerals will aid the kidneys in not having to work overtime in processing.
Processed food can be laden with chemicals and toxins, making it difficult for your pet to process.  Fatty diets and high carb diets again make the kidneys exert a great deal of energy.  When the kidneys and liver have to work overtime eliminating things that are bad it decreases the ability to repair continuing the downward cycle.
Mom always said to eat your greens, so should your pet!
Kelp is a great anti-inflammatory and helps to balance the thyroid.  Chlorella and spirulina have 12 times the protein than that of an ounce or so of milk! Barley and wheat grass are chock full of vitamins and minerals that animals need and digest easily.
A well balanced diet can aid your pet in processing medications it must be on if any, by boosting the immune system and allowing the body to rest in the areas it needs to in order to aid in healing.
Work with a veterinarian tor animal nutritionist to devise a nutritional plan that aren't quite as taxing on the organs. Holistic veterinarians are well versed on alternative medicines that can help ailing kidneys and improve function.
Something so simple can extend the life of a beloved pet and its quality of life!
