Kidney problems and canine nutrition

 

Most kidney issues are related to a loss of kidney function, this causes the kidneys to have a  reduced ability to filter the blood, which leads to a build-up of waste. This can be excessive amounts of creatinine, urea, or imbalances to the phosphorus, calcium, potassium and sodium levels. It’s also highly likely to see raised liver enzymes as well.

 

Many dogs prescribed renal food by Royal Canin will have kidney disease. A progressive disease that is extremely variable depending on how early it is diagnosed and by how well it is managed. The most important factor in the management of the disease is the diet that you feed your dog. 

 

Digestion is the breakdown of food and distribution of nutrients via the bloodstream around the body. All blood is filtered by the kidney, so what you feed your dog is vitally important if they are suffering from kidney issues.

 

If you’d like to know more about Canine Kidney Disease and nutrition, I’ve written a research article here.

 

What’s in the Renal Diets made by Royal Canin?

There are quite a number of issues with the ingredients in Royal Canin Renal Dog Food. 

 

  1. Highly processed food
  2. High in human waste ingredients
  3. Terrible Recipe formulation
  4. Generic, should be different depending on stage/ issue.

What are animal by-products?

What causes canine kidney disease, and does Royal Canin renal food address these causes?

 

  1. Overall bodily inflammation – Inflammation reduction requires a natural, fresh and correctly balanced diet. Not a long shelf life processed food, which in fact will have the opposite effect.
  2. Increased waste in the food – Processed food made in massive factories is much higher in waste products, synthetic additives when heated create waste.
  3. Gut Microbiome dysbiosis (wrong diet) – A natural balance of the gut microbiome can only be achieved with a natural fresh food diet.
  4. Chronic bacterial infection – Bacteria levels are managed by the gut microbiome and the food that nourishes it.
  5. High blood pressure – High blood pressure levels come from too high carb diets and low quality fats, which can be found in this food.
  6. Congenital or at birth malformation of the kidneys – this is extremely unlucky, but fresh food support is vital.
  7. Vitamin D deficiency – Prescription diet dog food has killed dogs before due to vitamin D toxicity. 
  8. Prolonged periodontal disease – Kibble gets stuck in a dogs teeth (if you’ve ever eaten a biscuit you’ll know that you have to use your finger to get rid of the remnants. Processed wet food has more waste that stains the teeth.

It’s unsurprising that their food isn’t healthy, here’s what Mars normally make.

 

How does Royal Canin Renal food work?

 

Royal Canin renal dog food may reduce certain markers in the blood test as it’s super restrictive, creatinine, phosphorus, calcium etc. but your dog will likely suffer in other areas of their health due to the extreme levels of restriction. E.g. the low quality and extremely low quantity of protein will reduce creatinine in the short term, but could easily cause reduced mobility, skin issues, hair loss etc. in the future.

 

This is also not a recommended option for earlier stage dogs at all, who don’t need such high levels of restriction. The reason why Royal Canin have chosen to be so limiting in nutrients is so all dogs, at any stage, show a decline in blood markers, causing vets and owners to assume it’s working. 

 

The truth is, you’re wasting around £10 per 1kg or $14 per 1kg on a generic food, high in human waste ingredients, in a smelly and bland meal that’s not really any different to a normal dog food.

Why is Royal Canine Renal Food recommended by Vets?

 

It’s crazy to think that healthcare professionals are recommending “therapeutic diets” that are made with human waste ingredients by chocolatiers, to sick dogs. Here’s how it go to this stage:

 

In the UK there are seven universities offering degrees in veterinary science. Nutrition however, plays a minor role in their education.

 

The average Vet only receiving 19 hours of nutrition training for all animals. 

 

I’ve spent around 910hrs learning about dog nutrition, just dogs. 

 

A lack of education and chronic underfunding (or in some cases just greed), many universities are very open to external sources of revenue and are happy to accept ‘sponsorship’ from companies despite glaring conflicts of interest, has meant that over decades, The Big Three (Colgate, Mars and Nestle) have exploited this situation to develop ever closer ties with vet schools around the world, providing funding and education.

 

The Nutrition Textbooks

 

Royal Canin’s best-known texts are the Encyclopedia of Canine Clinical Nutrition and the Encyclopedia of Feline Clinical Nutrition.

 

It probably won’t surprise you to hear that these texts are not what most people would call ‘impartial’ on the subject of pet food. 

 

As an example, the Canine Encyclopaedia dedicates more space to promoting Soy Protein Isolate Hydrolysate (a common Royal Canin ingredient) than it does to exploring the entire subject of home-preparing a fresh food diet.

 

The very last sentence in the entire textbook perfectly summarises how Royal Canin consider your sick pets: “Ideally, space should be organized in such a way that owners are led to buy a new supply of food for their dog, and even to buy new products for the dog that they have not seen before (e.g., chewing bars for dental hygiene)”.

 

This book is one of the primary sources of information on pet nutrition for vets. Unfortunately, your Vet knows little to nothing about nutrition.

 

Legal action against prescription pet food

Because the foods are so low quality, their association with Vets is being considered as deceptive and their marketing as being different to normal dog foods, as fraudulent.

 

MOORE V. MARS PETCARE US – California Court of Appeals 2020

 

The panel concluded that under the reasonable consumer test, plaintiffs sufficiently alleged that the sale of the prescription pet food exclusively through vets or with veterinarian approval was a deceptive practice. 

 

Also, plaintiffs satisfied the heightened pleading standard for fraud because they alleged sufficient facts to show that prescription pet food and other pet food were not materially different.”

 

Your next steps

 

The power of food is that it can make a dog healthier. Just like with us humans, when we start eating a super healthy diet, it undoes the damage of an unhealthy diet.
