Pet Plus For Dogs - New Formulation

We've decided to make a small change the formulation of Pet Plus for Dogs by adding taurine. PET Plus for Cats has always contained taurine.

This means that from now on, PET Plus will be the same for both dogs and cats.

Why Add Taurine To Pet Plus for Dogs?

It has always been known that dogs make their own taurine, so taurine deficiency has rarely been a problem ... until now. Over the last few years, increasing numbers of dogs are being diagnosed with clinical problems associated with taurine deficiency. 

Taurine is actually an amino sulfonic acid, although it is loosely referred to as an amino acid.  It is essential for cardiovascular function, skeletal muscle development, central nervous system development and the function and healthy workings of the retina. 

Taurine And Cats

For decades this has been recognised as a potential problem for cats which, as a species, are unable to make their own taurine from their diet. So taurine is one of the essential amino acids for cats which has been specifically included in all AAFCO approved cat foods and most supplements.

Naturally, feeding on whole herbivores, raw, they obtain plenty of taurine because bile is a particularly rich source.  Raw meat and fish contains plenty of taurine, as do raw heart, brain and offal. But cooking denatures taurine in the same way as it denatures all proteins and enzymes.

But What About Dogs?

In all mammals except the cat family, taurine is naturally synthesized in the body from cysteine, an amino acid, and homocysteine, by an enzyme pathway, in the pancreas.

Interestingly, pancreatitis is rapidly becoming a common problem. I suspect this is associated with the prevalence of feeding processed foods which are by definition deficient in enzymes, causing the pancreas to work ridiculously hard to produce the enzymes to digest the food whose natural enzymes have been destroyed. Crazy isn't it!

Did you know that the pancreas of rats fed a processed diet for a month was 3 times larger than the rats fed the same ingredients but raw? The pancreas is responsible for the creation of taurine from dietary ingredients, namely an amino acid called cysteine. An exhausted pancreas is unlikely to be able to perform this task effectively.

Besides which, amino acids, such as cysteine, are denatured by processing. So let's join up the dots here. Can we conclude that feeding processed foods is causing the increase in taurine deficiency in dogs? I think we can. Yes!

Health Problems Due To Taurine Deficiency

We now know that there are several clinical situations associated with taurine deficiency in all species, including dogs, cats, humans, rabbits, rats ... in fact ... all mammals.

Central Nervous System (CNS)

Taurine has been shown to cross the protective blood brain barrier to enter the brain, where it performs numerous functions, including stabilizing membranes and inhibiting neurotransmission. Both these functions could reduce the generation of epileptic impulses and seizures. 

Believing that epilepsy was a specific situation, dogs presenting with recurrent epileptic seizures have been successfully treated by increasing their taurine intake. We used to give them Pet Plus for Cats, which has always contained taurine as cats are unable to make their own.

Some people bought taurine from health food shops and gyms to give to their dogs. So we decided to include taurine in Pet Plus for Dogs as well, to address this increasing clinical situation. After all, prevention is better than cure!

CardioVascular Disease (CVD), Most Notably DCM (Dilated CardioMyopathy)

Here, the muscle of the heart wall weakens so the heart is unable to pump effectively. The weak heart wall gradually stretches, becoming thin and increasingly unable to pump the blood out of the heart and around the body or to the lungs.

Fluid accumulates in the lungs and body, leading eventually to all the symptoms of congestive heart failure, including increasing breathlessness, exercise intolerance, inability to climb stairs or walk up hills, coughing and increasing exhaustion.  

This condition seems to be more common in the following large breeds of dog, indicating a potential genetic predisposition to Taurine deficiency.

  • Golden Retrievers
  • English Setters
  • Newfoundlands
  • St Bernards
  • Portuguese Water Dogs
  • Cocker Spaniels
  • Irish Wolfhounds

Thankfully, this is all reversible by the administration of taurine. So why not give it everyday, to prevent the risk?

Skeletal Muscle Weakness

Taurine deficient mice have been experimentally shown to suffer weakness of their skeletal muscles as well as their cardiac muscles. I am not aware of any such reports in other mammals, but it may well be that pets suffering from DCM are actually also suffering skeletal muscle weakness, but the symptoms are attributed solely to the DCM.

Central Retinal Deterioration

The retina gradually deteriorates causing progressively worsening eyesight and eventual blindness. In cats this is irreversible, but once the condition is recognized and diagnosed, supplementing with taurine can prevent further progression.

It seems to be the same situation in dogs, although to date, it is less common as a cause of retinal problems in dogs than it is in cats.

Cystitis And Bladder Infections

As described above, inability to metabolize cysteine can result in taurine deficiency, because taurine is made in the body (except in cats) by specific enzymes from cysteine and homocysteine.

If the cysteine is not metabolized, it can be excreted by the kidneys and bladder, where it can accumulate and form crystals. These sharp cysteine 'stones' can irritate the bladder wall resulting in cystitis. Symptoms include frequent urination, increased thirst and possibly blood in the urine.

Prevention of this cause of cystitis involves using an enzyme supplement like Pet Plus, feeding raw food and ensuring an adequate supply of fresh, chemical-free water at all times. Absolute avoidance of dry foods will also help to maintain urine flow and prevent the stagnation that allows the crystals to form in the bladder. Again, there seems to be a breed disposition, including

  • Newfoundlands
  • Austrian Shepherds
  • Chihuahuas
  • Basenjis
  • Basset Hounds and
  • Scottish Terriers


So, to summarise, it is simple to prevent taurine deficiency with diet and suitable supplementation. However, it is a challenge to recognize and diagnose taurine deficiency as the symptoms are shared by other causes.

A blood test can be performed to measure the blood levels of taurine, but that only shows what's in the blood at that exact moment which does not necessarily relate to the absorption and use of taurine in the actual body tissues, e.g. muscle, retina, brain and heart.

As always, enzymes are essential for the proper functioning of every single cell in every single body. So be sure to give your pets plenty. And make sure you have plenty of enzymes yourself too, so that you too can manufacture your own taurine.

  1. Hi, can you provide me with a comprehensive list of ingredients? I'm struggling to find it on the website

    Many thanks

    1. Thanks for your query Shelley.

      All the ingredients are written in the post under Ingredients, which appears in the menu at the top of every page on the site. But here is the direct link.

      The formulation will change in the next few months, with some different ingredients and proportions, when I make my next batch.
      So, currently, the ingredients list for the Pet Plus powder is:

      • 7 different enzymes
      • Lactobacillus acidophilus
      • Lactobacillus plantarum
      • Beet root powder
      • Brewer's yeast
      • Nutritional yeast
      • Flax seed
      • Hemp seed
      • Cracked cell wall chlorella

      • Wheat grass juice
      • Barley grass juice
      • Bilberry extract
      • Astrazyme
      • CoEnzyme Q10
      • Taurine
  2. Hello. I’ve been gifted a container of PetPlus for Cats from a friend who used to use it for their cat (no longer as the cat sadly passed). I have a dog, not a cat and was wondering if the cat formula is safe for dogs. It’s a container from a while ago so I’m not sure if it’s the same formula as the PetPlus that’s suitable for both cats & dogs. Thanks ☺️

    1. Hi Taylah,
      Thanks for your enquiry
      The formulation for cats that you have been given is perfect for your dog! Check that the powder has been kept dry and cool, that it still is a free flowing powder and that it smells good (not rancid). How much does your dog weigh? Give 1 tsp per day for a big dog (over about 15 kgs), 1/2 tsp for medium dogs (7.5 to 15 kgs) and 1/4 tsp for little dogs (up to about 7.5 kgs). You can split this between meals and also you can happily give much more! It's all whole food based so it isn't possible to overdose!
      Enjoy seeing the improvements.

  3. Great post-thank you. We love your product and have been using it for years now. It’s been a godsend for our Mini Schnauzer. He used to suffer terribly with pancreatitis when younger but is now in great health. We’re excited to try the new formula.

    1. Yes indeed it will! All Pet Plus for Dogs and Cats now contains Taurine. There's an article on my site explaining why.

  4. Been feeding pet plus for a couple of years now and the dogs are doing very well on it. I feed cooked home made food, plenty of veg and your Pet Plus. Will the extra taurine be safe and not be too much as they don’t have kibble. Never have!

    1. Thanks Ann
      Sadly, cooking food destroys the taurine, enzymes, other amino acids and micronutrients, making it hard for any body's body to make its own taurine. So yes, they need the taurine in Pet Plus.
      On a raw diet, there will be some dietary taurine, but the body still needs to make more. So taking extra in the Pet Plus just makes life easier for the pancreas as it doesn't need to make so much.
