Kidney Disease- A Natural, Holistic Diet To Support Renal Function

Kidney disease is common in pets, particularly as they get older.

Whatever the cause (and there are many – the most common being damage caused by poisons, toxins or drugs; infections; poor blood flow and cancer) renal dysfunction is usually progressive as more and more healthy kidney tissue is lost.

This results in an increasing inability of the kidneys to remove the waste products of protein breakdown from the blood (mainly BUN and creatinine) so that they can be excreted from the body in urine.

As a consequence, their levels in the blood rise over time and cause many of the signs associated with kidney failure, such as:

      • an increased thirst
      • more frequent urination
      • bad breath
      • loss of appetite
      • a sore mouth
      • nausea
      • lack of energy
      • vomiting
      • weight loss
      • poor body condition

Disturbances in fluid and electrolyte balance can also occur, resulting in additional signs of ill-health.

The prognosis when renal disease is diagnosed depends on:

      • the cause of kidney damage (where this is a rapidly growing cancer for example, renal function is likely to deteriorate much more rapidly than when the underlying cause is poor blood flow as a result of heart disease)
      • how far the disease has progressed when the diagnosis is made (creatinine only rises when approximately 75% of kidney function is lost, whereas SDMA increases with as little as 25% kidney function loss)
      • the presence of other diseases in the body (conditions affecting the immune system for example, can seriously hinder the body’s natural healing processes, which are important for renal tissue repair. IBD and other digestive disturbances can interfere with the assimilation of nutrients from the diet, which are important for supporting renal health.)

In general, the earlier the diagnosis, the less aggressive the underlying cause and the smaller the amount of damage, the better the outlook for prolonging quality of life.


The first step is to treat the cause of the kidney damage if this can be identified.

If this is due to poor blood flow because of a heart condition for example, the appropriate cardiac support should be provided.

If it is due to the side-effects of drugs, then alternatives are best found which don’t harm the kidneys.

And so on.

In many cases however, it’s not possible to identify why renal dysfunction (the early stages of kidney disease when SDMA is raised) or failure (the later stages when the kidneys are struggling to filter the blood and both creatinine and BUN are high) has developed.

The second step is to feed a diet which supports renal function and promotes overall health.

Natural, Nutritious and Chemical Free

The aim of a renal support diet is to maintain quality of life for as long as possible, by:

      1. Feeding a highly nutritious diet which promotes optimum health while at the same time minimising the amount of waste products arising from protein metabolism (urea and creatinine).
      2. Protecting and preserving renal function.
      3. Strengthening the immune system.
      4. Promoting tissue healing, regeneration and repair.

Although there are commercially produced pet foods available for dogs and cats with kidney disease, many are highly processed and contain chemical additives which are potentially harmful to health, and so are less than ideal for sick pets.

A healthier option whenever possible, is to feed a high quality raw or home prepared diet, which takes into account the individual nutritional needs and circumstances of each individual pet.

For the best outcome, this should be:

As a consequence, their levels in the blood rise over time and cause many of the signs associated with kidney failure, such as:

      • easy to digest
      • highly nutritious
      • free from chemical additives and pesticide residues
      • rich in nutrients which support renal function and combat the ill-effects of kidney disease on the body

A Natural, Holistic Renal Diet

Please note – kidney disease is serious, and pets with this condition need careful monitoring with regular blood tests and frequent adjustments to their dietary regime and any medication prescribed, if they are to live a good quality life for as long as possible.

The guidelines below are for information only, to highlight some of the measures that can be taken which have proven beneficial for dogs and cat with renal dysfunction and failure in the past. These are best undertaken with the help of a fully qualified and experienced holistic vet.


1. Stop feeding all other foods apart from those described below.

2. Feed a high quality raw meat bone and offal food (or home cooked minced meat if preferred).

We recommend feeding Vince the Vet Superfood Raw because it contains only the highest quality, fresh, natural ingredients (and NO vegetables, fruits, grains etc.) and is specially formulated to provide maximum health benefits.

(The second commonest herbicide found in vegetables and fruits on sale in UK supermarkets, is the weed killer glyphosate which is known to be harmful to health).

Most tinned and dry dog food (and treats) contain these ingredients, plus chemical additives which are potentially harmful to health, which is why these too are best not given.

3. Avoid any pet food, tit-bit or treat with non-organic vegetables, fruits, grains, herbs or botanicals in whatsoever. Most of these contain pesticide residues (see the Pesticide Action Network report on this here) which are TOXIC  to the kidneys.

4. Supplement with:

Digestion – aids the assimilation of nutrients from the diet, which often becomes impaired as the body excretes waste products from the blood into the gut to ease the load on the kidneys. It also replenishes many of the vitamins lost in urine each day which are important for a feeling of well-being and a good appetite.

Vitality – provides a rich supply of nutrients necessary for kidney healing and repair (amino acids, fatty acids, vitamins, minerals, trace elements and many others). Scientific research has also shown that the anti-oxidant properties of the ingredients help to protect the kidneys against damage caused by poor renal blood flow – which is common in kidney disease.

Immunity – supports the body’s natural defence mechanisms in guarding against infections.

Salmon oil – supplies fatty acids essential for hormone regulation and the body’s natural, anti-inflammatory pathways. A product made from fish caught wild in Alaskan / Icelandic waters is best.

Coconut oil – helps to boost mental alertness and is a good source of non-protein energy. Pure, organic, cold-pressed virgin is best.

5. Give homeopathic Urea Puris 30c twice daily (available from Ainsworth’s) to aid the excretion of waste products from the body.

What’s possible


“I would like to thank you for all your continuing support with helping Fen (our beautiful Lurcher who is coming up to 14 1/2 years), especially earlier this year when he was diagnosed with chronic kidney disease.

Your treatment of homeopathy, supplements (Vitality, Immunity and Digestion) and working out a diet with the right levels of protein and phosphorus, have all helped his condition to improve significantly.

We’ve had regular blood tests since April of this year and each time they have improved. The last ones in September showed the BUN (blood urea nitrogen) is still normal, the creatinine has fallen and calcium and phosphorus levels are in the normal range too. So with your help we are managing it very well.

This isn’t the first time we’ve had amazing results with Fen with you. We first met you in March 2016 when Fen had being diagnosed at the end of 2015 with a chronic chest condition similar to asthma and was on a nebuliser daily. By August 2016 his cough had improved sufficiently following homeopathy and the introduction of Vince the Vet Supplements, for him to come off the nebuliser, and he is still doing very well.

I can’t find the words to thank you enough, as Fen is so bright and loving life.

I wouldn’t hesitate to recommend Vince to anyone looking to improve their pet’s health”

Once again thank you.”
