Kidney Disease in Pets ..

Traditionally, vets have recommended restricting protein consumption because protein is poorly metabolized by dogs with kidney failure. Protein creates a high nitrogen load that can further stress the liver and kidneys. The problem is, that most commercial pet foods are made of poor quality protein that is not easily digested or utilized and this is what places the stress on the kidneys.

It’s estimated that over half of all pet cats over the age of 10 suffer from chronic kidney disease (CKD), which is also often referred to as chronic renal disease or chronic renal failure.

Traditionally, vets have recommended restricting protein consumption because bad quality protein is poorly metabolized by dogs with kidney failure. Protein creates a high nitrogen load that can further stress the liver and kidneys. The problem is, that most McKibble and McCan are made of poor quality protein that is not easily digested or utilized and this is what places the stress on the kidneys. To get quality proteins that are easily digested into your dog, a fresh food diet should be fed.  Kibble is not a good option for these dogs.

The second reason kibble can further stress dogs with kidney failure is that dry food is very low in water (15 to 20% compared to 80 to 85% in fresh foods). Kidney disease dehydrates your dog and the dehydration causes him to feel ill – just like a hangover. He will have much better luck at staying hydrated if fed a fresh diet.

Generally speaking, kidney disease involves any insult (do harm) to the kidneys. If the insult continues, the kidneys can experience failure. Kidney failure can be divided into either acute or chronic failure.

As stated by Dr Messonnier is his book “Natural Health Bible for Dogs and Cats”, acute failure can occur in dogs and cats of any age, although most commonly younger pets are affected. Acute failure can occur from a number of causes. Pre-renal causes (not directly involving damage to the kidney) of acute failure include low blood pressure, low blood volume, heart failure, and certain medications such as non-steroidal anti-inflammatory medications and ACE inhibitors such as enalapril.

Renal causes (involving direct damage to the kidneys) include intrinsic kidney diseases, toxins that directly attach the kidneys (such as antifreeze poisoning or aminoglycoside antibiotics), cancer of the kidney, kidney trauma (kidney stones, direct trauma), congenital disorders (polycystic kidney disease, renal cortical hypoplasia), and infections (leptospirosis in dogs, feline infectious peritonitis in cats). Post-renal causes (involving a blockage or urine outflow from the kidneys or bladder) or acute failure include bladder stones, urethral stones, bladder cancer, and feline lower urinary tract disease (including urinary tract obstruction that is most commonly seen in male cats).

When kidney failure is acute, symptoms come on quickly and are often severe. The top three to watch for are:

  • Vomiting
  • Complete loss of appetite
  • Marked lethargy

Other symptoms you might notice:

  • Straining to urinate and decreased urine production
  • Disorientation
  • Physical weakness; loss of coordination

Acute renal failure is a very serious, life-threatening situation and fast action is required if there is to be any hope of saving your dog’s life.

Please Note: As stated by Dr Becker, the food you feed your fur kids with chronic renal failure is critically important for disease management and overall well-being.  A reduced amount of high-quality protein and high moisture content are essential, but phosphorus intake must be restricted. Since phosphorus is found primarily in high protein food sources, you can quickly see the need for expert guidance on how to best nourish your pet.

Your integrative / holistic vet [see our independent directory] is your best resource for advice on the right diet for your pet’s condition, and also what supplements, medications if necessary, and other therapies will help sustain your dog’s health and quality of life.

Not every cause of canine kidney failure is known or understood, nor can every case of acute renal – or chronic renal failure be prevented. However, there are a number of things within your control that can go a long way toward promoting the health and longevity of your precious pup’s vital kidney function.

  • Many situations of acute renal failure can be prevented by ensuring dogs are kept safely away from toxic substances like antifreeze, heavy metals, rat poison and other pesticides, common household medicines, and certain foods and plants.
  • Any dog with a bacterial infection, urinary obstruction or other illness that could lead to compromised kidney function should receive proper treatment, the sooner the better.
  • Limiting the drugs, vaccines and surgical procedures your pet is subjected to throughout her life will reduce the amount of toxins her liver and kidneys must process. Kidney failure in elderly dogs is usually the result of worn out organs. The less stress on your pet’s kidneys, the longer they’ll do their job effectively.
  • Feeding a balanced, species-appropriate diet instead of commercial pet food will supply your dog’s body with the fundamental nutrition he requires for the health of every organ and system in his body, including his kidneys. Low quality, highly processed pet foods – in particular dry kibble, which lacks the moisture content and quality protein pets need — are being linked to many of the degenerative diseases seen in pets today.
