PET Plus Supplement Ingredients

We're constantly reviewing the PET Plus ingredients as new nutrition research emerges. To that end we've recently improved the Pet Plus formulation. Please read this page and also the one that explains why we added taurine for dogs for full details.

Dr Susanna McIntyre

As more and more research is completed on the effectiveness of various nutrients and micronutrients, so new recommendations emerge for supplementing the diets of cats and dogs, and of course, humans.

At Pet Plus, we keep abreast of this new information, so we are constantly improving the formulation of Pet Plus.


Did you know that enzymes are essential to health but that they don't exist in processed food?

Raw food is full of enzymes. Enzymes are essential for life, so every living cell has plenty. But enzymes are destroyed by heat and exposure to various chemicals. This is why processed food contains no enzymes.

Fortunately though, the body is capable of making enzymes, and does so in order to digest the food.

The body can make enzymes but it is seriously hard work which can wear it out!

But making enzymes is an energy expensive process, and particularly hard work for the pancreas. As a result, pancreatitis is becoming increasingly common, as an overworked pancreas becomes inflamed, painful and unable to fulfill its function.

PET Plus Enzymes

In Pet Plus, we've used Proteases and AstraZyme for protein digestion, Amylases for carbohydrate digestion, Lipases for fat digestion and blend of highly active enzymes for the digestion of vegetation.

On a processed food diet, these enzymes are critical for the proper digestion and assimilation of the nutrients, as enzymes are rendered inactive by the heating involved in the production of processed foods.

Also, many pet processed foods are bulked out by cheap cereal based fillers which are very difficult for dogs and cats to digest and totally inappropriate for a carnivore.

The addition of Pet Plus to processed food facilitates digestion, easing the load on the pancreas and enabling your pets to gain more nutrition from their food.

Cats and dogs need vegetables in their diet. Who knew?

Fed a raw food diet, the enzymes in Pet Plus help with the digestion of the raw food, especially the vegetation. Dogs and cats are not good at digesting vegetation, but they need it!

Cats and dogs would normally access most vegetable nutrition from the intestinal contents of their prey, where it has already been well chewed, partly digested and is full of vegetation-digesting enzymes and probiotics.

So the blend of highly active enzymes in PET Plus for the digestion of vegetation is especially important.

Dogs And Cats Need Probiotics

Lactobacillus Acidophilus and Lactobacillus Plantarum are a complementary pair of the best probiotics for dogs and cats. They colonize the gut easily, create an environment that discourages pathogens and do not transfer antibiotic resistance, unlike some other probiotics.

We decided not to use several other probiotic species as Lactobacillus Acidophilus and Lactobacillus Plantarum work well together. They are found in the intestines of all carnivores and the herbivores they eat.

This dramatically impacts their ability to digest food and so aids a healthy digestive system. This is of great benefit to everyone within sniffing distance!

Saccharomyces cerevisiae (Brewer's and Nutritional Vegetarian Yeast) is also an important probiotic and has been a major ingredient of Pet Plus since its original creation in 1996.

Probiotics have also been shown to be critically important in maintaining a healthy immune system. This is especially key in these times of increasing antibiotic resistance.

If your immune system can protect you from pathogenic invaders, the need for medication, like antibiotics, is vastly reduced.

Cats And Dogs Need Prebiotics And Antioxidants

Fructo-Oligo Saccharides (FOS) are known to be the very best prebiotics, providing so much support for the existing healthy gut flora that supplying probiotics is almost unnecessary!

We decided to do both with Pet Plus, to give our dogs and cats the best of both worlds! Frutafit Inulin IQ is the patented source of the most effective of all the fructo-oligosaccharides in a whole food form.

We've chosen this prebiotic nutrient to support the probiotics as it is plant based, very palatable and completely natural.

Alfafa, wheatgrass, barley grass and beetroot fibre are all included

Alfalfa, wheat grass and barley grass have been pulverized and juiced then carefully dried so that all those fabulous nutrients, which would otherwise be hidden inside the cells, are preserved without chemicals and readily available to our pets. The beet root fibre is also a great source of fibre.

Together, these five ingredients are an essential support for the probiotics and provide an enormous number of antioxidants, vitamins, minerals and phytonutrients.


As part of a group of nutrient dense aquatic plants, the single-celled Chlorella algae is attracting a lot of well deserved attention.

It contains a staggering array of nutrients and micronutrients of great benefit to us all - people, cats and dogs! Chlorella is the richest source of chlorophyll. Chlorophyll is a photosynthesizing molecule closest in structure to the oxygen carrying haemoglobin molecule in animals.

Chlorella is an excellent source of essential fatty acids (EFAs), notably the anti-inflammatory Omega 3. Chlorella also contains numerous minerals, vitamins, antioxidants, phytonutrients, proteins and plenty of probiotic-supporting prebiotics.

All this is readily available for absorption by our dogs and cats as we have chosen the very best quality cracked cell wall Chlorella for Pet Plus. As this nutrient dense plant is incredibly green, the Pet Plus powders are green when dry and stay green when mixed with wet food!

Cats also love Chlorella, as I discovered when I dropped one of my Chlorella tablets on the floor and he quickly gobbled it up. I was amazed!

Have you noticed that blueberries are everywhere?

Bilberries (Or Blueberries)

You have probably noticed the sudden increase in popularity of bilberries. They are rich sources of antioxidants, resveratrols and numerous other highly active 'superfood' micronutrients.

These things work together to protect our cells from free radical damage, inflammation and numerous other challenges.

Hemp Seeds And Flax Seeds

Excellent sources of essential fatty acids (EFAs), hemp and flax seeds supply the perfect balance of omega 3, 6 and 9 for dogs and cats. Omega 3 is especially important these days as it is has potent anti-inflammatory properties, protecting the integrity of cell membranes throughout the body.

Other EFAs form the building blocks for hormone production, essential for the body's internal communication mechanisms. Hemp and flax are also rich sources of antioxidants, vitamins, minerals, complete proteins and phytonutrients and support the probiotics.

As the seeds themselves would be difficult to digest, we have powdered them.

Brewers Yeast And Nutritional Yeast

Repelling parasites and supplying plenty of B vitamins are the main roles of these yeasts. Technically known as Saccharomyces cerevisiae, they are also important probiotics. Tasting delicious, they also provide many other important nutrients as well as enhancing the flavour.

Dogs and cats love the taste of nutritional yeast!

They are completely harmless, being unrelated to the pathogenic yeasts, which occasionally colonize inflamed areas of pet bodies, most notably the ears.

Cats and dogs love the taste of nutritional yeast, helping them to enjoy Pet Plus in their food. Cats happily lick Pet Plus off their fur, while dogs are quick to lick it off the floor when the opportunity arises.

Coenzyme Q 10 (Ubiquinone)

Efficient energy production by the cells is critical for health. Coenzyme Q10 (20mg per teaspoon of Pet Plus) is an essential co-factor for the release of energy from food in the mitochondria, the energy powerhouses of every cell.

This fuels all the body's systems, enhancing the smooth running of the whole body, especially the immune system and the cardiovascular system.


Taurine For Cats

Taurine is essential for feline health. Cats are unique in their inability to make it themselves from other dietary ingredients. So a plentiful supply has always been provided in Pet Plus for Cats.

It's presence is associated with a healthy cardiovascular system, eyesight and neurological function. It prevents the cardiomyopathy, retinal degeneration and epilepsy which can occur when dietary taurine is deficient.

Taurine For Dogs

An increasing number of dogs seem to be suffering from taurine deficiency, so we have now added taurine to Pet Plus for Dogs. However, this now means that the formulation for dogs is now the same as for cats, so there is now only one type of Pet Plus, so it will no longer be separately labelled as Pet Plus for Cats and Pet Plus for Dogs. It will be labeled as Pet Plus for Dogs & Cats!

Please see the article I've written which explains why dogs also need taurine.

Summary - Synergy With Nature

The key to successful nutritional supplementation is to use the ingredients found in nature in their whole form.

There are at least 15,000 micronutrients in raw food which all work together, synergistically. If we isolate these to make individual vitamins, we are removing the very things we need!

Always go for whole food based nutritional supplements and avoid isolates! Why? Because Nature knows best!

  1. I have always used your Pet Plus on my 5 cats raw food however one of my Maine coons has had to come off raw food today as she has IBD flareups and is no longer tolerating it. She is also anorexic. I have to do what is best for my cat and albeit rather reluctantly having to give her Gastro intestinal dry and wet food. She has just had a lab blood profile done and shows folate has increased and are seen with bacterial overgrowth. My question is, would it be safe to still sprinkle the petplus over my cats food as my vet is recommending Fortiflora and says brewers yeast in the petplus may be contributing to her very bad Diarrhoea and pain.Any advice would be most appreciated.

    1. Thanks for your question.
      Yes, definitely keep adding Pet Plus to her food. She needs it now more than ever.
      The brewers yeast is actually a probiotic called Saccharomyces cerivisae.
      So the question is, what is irritating her bowels? Is there a particular raw food she can't manage any more? Wild rabbit is usually the best, cleanest one to use.
      Keizerbrink have a huge selection of minced herbivores to feed out carnivores!! Raw pet supplies in Cardiiff, Wales (if you're in UK) are excellent suppliers of the biggest range I have ever seen!!!
      Have you tried some of the vegan suggestions here on my website, like chia porridge? That's a great tummy calmer with easily digested nutrients. (mix chia seeds with water and Pet Plus; the chia seeds soak up the water and they love the resulting porridge!!)
      Always use filtered / bottled water, never ever tap water as the chemicals are really irritating for the entire body.
      Have you read the article 'Health promoting lifestyles for dogs and cats' here, on my website? That details everything to do and not do to keep our beloved furry friends healthy!
      Let me know if you need more help. I'm very happy to help!

  2. I am following home cooked recipes for my 2 dogs and i was wondering if this is a) good for dogs with allergies (he is still in the process of testing and is on allergy shots in the meantime), and b) if this is low enough in fats that it won't agitate a dog with sensitive tummy (oils and high fats upset him and give him indigestion), and c) how much daily do i give a 14kg dog and an 18kg dog if all i can get is one small container per household per month? And d) if they are being fed organ meats as well as a variety of meats (horse, kangaroo, venison/deer, turkey, beef, lamb, pork, etc) - will the taurine they get naturally fromt these foods be too much when added with this supplement?

    Does the supplement have added calcium? I am giving eggshells right now and don't want to overdo it (or the phospherous). Thank you!!!

    1. Thanks for your well structured email!
      The best food for all animals is raw, as nature intended. Cooking damages the nutrients, so while home cooked food is much much better than dried or tinned manufactured pet 'food', raw is better.
      Adding Pet Plus to the food you're cooking puts many of the nutrients back into the food, so enhances its digestion, absorption and utilization by the body. So for your specific questions,
      a) yes, because it supports a healthy (not over-reactive) immune system. What are the 'allergy shots'?
      b) the enzymes in Pet Plus will allow him to digest any dietary fats he has. The EFA ('oils') in Pet Plus are raw and easily digested, especially with all the enzymes in Pet Plus.
      c) They each need a teaspoon a day, so the small pot will last you 2 weeks, so then you can order another one. We are in a difficult position at the moment with the challenges of supply chain disruption with the 'pandemic'. So we had to restrict the orders to prevent stockpiling in an effort to ensure everyone has enough to keep supporting their pets. We expect to be back to normal in late April or early May, but everything is so ridiculously unpredictable at the moment. I can only apologize and keep working my socks off to get the new supply as soon as possible.
      d) The taurine levels will be great. Sounds like you've got a fabulous supply of meats. Remember to give raw meaty bones too, or pulverize the raw bones and mix them in with the minced meat. It's all so much better fed raw!
      e) The full spectrum of minerals is bio-available from the range of whole foods used to create the Pet Plus. I don't add any chemically produced isolated minerals. Giving raw meaty bones is the best way to give them calcium to balance the phosphate in the meat. Nature has it all worked out, so in nature, carnivores eat meat and bone together. If they eat eggs, they eat them raw and often eat the shells as well; raw, these supply numerous minerals; cooked, the enzymes are destroyed, making it more difficult for animals to access the minerals. Plants absorb minerals and more from the soil, link them to enzymes, then when eaten by an animals, the mineral-enzyme complex is easy to use. Animals eating soil are challenged to access the minerals.
      I hope that answers your questions!

      1. Thank you so much!

        I am a huge advocate of raw and have raw fed my previous 2 dogs for 8 years and these current 2 for several years but last year the small one developed issues where he cannot digest or handle raw any longer so we switched to decent kibble but while tummy/indeigestion issues completely cleared up, allergies started in full force. We are working on finding out what he is allergic to but in the meantime we are finding homecooked is a good medium between the two and just want to make sure he is getting a decent balance while we figure everything out 🙂

        1. Thanks for giving us the details. That must have been a difficult decision to go for kibble! What a shame that set of a bunch of allergies, but at least you then had to stop the kibble!!!! Every cloud has a silver lining!!!
          You will probably find that after a few months on Pet Plus with your home cooked food, that you can go back to raw.
          I would suggest you make all changes slowly and a little bit at a time, as he is such a reactive and delicate state.
          So when your Pet Plus arrives, start with just a few grains of the powder in his food, then every few days, increase the amount, till after a couple of weeks, he is having the full amount.
          I'd recommend using a herbal wormer, like Verm-x. Avoid chemicals completely. And don't vaccinate. Out of interest, was he vaccinated soon before he started having problems?
          Filter all your water, so they (and you) have chemical free water.
          I look forward to hearing how you get on.

  3. Hi, could you please tell me if this would be ok to give my dog with stage 4 kidney failure and arthritis? she is in desperate need of quality nutrition

    1. Yes, absolutely.
      Make sure her water is chemical free, so filtered tap water would be great, or well water or from a borehole or a Spring (The Best!)
      Give her kidneys a rest from filtering chemicals.
      Raw food would be best also as it's so much easier to digest and delivers whole nutrients as nature intended.

      1. Thank you so much. I have been giving bottled water and tried her on raw paleo ridge senior special and she liked it but I noticed her breath changing a little so changed to home cooked and royal canin as the vet recommended but she has gone off the royal canin and is losing weight so trying her on raw again. Is there a specific amount of meat protein I should be feeding her per meal as to keep weight on her but not put so much strain on her kidneys? She is a collie cross Alsatian with a normal weight of 25kg but has lost some.

        Thanks again so much

        1. Hi Nicola,

          Have a look at the diet guideline sheet on this website.

          I'm so glad she has the sense to refuse the Royal Canin!!!! Crafty advertising and branding and pricing leads one to believe it's good!!! It's the same rubbish as all the other processed foods!!!

          Raw is the way to go.
          Raw protein is unlikely to give her kidneys any problem! Can she deal with fats OK? If she can, then raw fatty meat would be excellent, like chicken with the skin and lamb. That's the quickest way to gain weight.
          50:50 with blended greens and Pet Plus and all will be well.
          About 400g raw meat should be fine, but if she wants more, give her more, divided between 2 or more meals. Each meal with blended greens and Pet Plus.

          Between meals, like an hour before her meaty meals, give her lots of dried fruit, like dates, cranberries, non-sulphured apricots, prunes....but NOT any of the grape family (raisins, sultanas, currants) as they have been associated with renal failure, exactly not what you want!!!
          As with everything, introduce the dried fruits gently. I find dates to be the best, especially medjool dates.
          Then give her a stalk of broccoli or a carrot or something veggie and tough and fibrous to alkalize her mouth / saliva and clean her teeth....or brush her teeth!!

          I look forward to hearing how you get on.
          Best wishes,


  4. My working cocker suffers occasional bouts of pancreatitis. I was feeding her Nutriment raw, but recently changed to Forthglade which is described as 'gently steamed' as was told it would be easier for her to digest. Since then I watched discussion with Brandon Clark (who recommended Pet Plus) and Mick Thompson Holistic Vet, both advocates of raw. I'm confused!! Will Pet Plus help improve my dog's pancreatitis and would you recommend going back to raw, even though it's fat content is higher. (I'm about to order PetPlus for both my dogs).

    1. Thanks for your question.
      The short answer is yes, go back to raw and yes, Pet Plus has helped loads of dogs with pancreatitis. (If I made a 'health claim' about Pet Plus, the pharmaceutical industry would take me down, which is why answers from naturopaths tend to be a bit oblique, like this one!!! Stupid, isn't it, but they're just protecting their financial interests!!!)
      So now for a brief explanation.
      Firstly, I hope you have read all the information about pancreatitis on my web site. There's a great explanatory article.....
      OK, so the main job of the pancreas is to manufacture enzymes, largely for digestion of food.
      When the food is raw, it contains virtually all the enzymes required for its digestion.
      So the fat contains lipase to digest it, so there's no real need to worry about the raw fat content of raw food, as long as you're not feeding solely lumps of fat!!!!!! But I know you won't do that!
      Enzymes are very sensitive to heat (above 42 degrees C destroys enzymes) and chemicals. They are easily denatured and rendered useless.
      So feeding cooked or processed food means the pancreas has to make all the enzymes needed to digest this dead lump of 'food'.
      This is the basic cause of pancreatitis, because the poor old pancreas has to work much harder than it was ever designed to.
      Anything that is abused and overworked becomes inflamed in a desperate attempt to protect itself.
      Anything ending in 'itis' means inflammation.
      Think back to nature. Did we all evolve with cookers and tin openers in our back pockets?
      No, of course not!
      We're all designed to eat raw food.
      I've been a raw living food vegan (clearly I'm not going to eat raw meat!!!!) for 17 years and my health has improved dramatically.

      You mentioned that you think the fat content of raw food is higher than cooked. I'd love to know why you think that! Boiling meat for a while brings the fat out. I always remember skimming it off the boiled chicken when I was at home......some 50 years ago!!! But 'lightly steamed' should still contain its fat and texture I think.....although no enzymes of course, so it's very hard to digest!

      There are various raw carnivorous options that have less fat than many others.
      Green tripe is a great food to use 3 or 4 times a week. It doesn't contain bone or much muscle meat, so on the other days of the week, you could use wild rabbit, turkey or white fish . These have less fat than lamb, beef, chicken, duck, goose, oily fish or factory farmed rabbit
      After a few weeks, you could give her some heart, offal and organ meats a couple of times a week. They're rich in numerous important nutrients, but have very little fat.
      There are numerous vegan options too. Have a look at the articles I wrote on my website.
      Dogs don't always need to eat meat. They're much more adaptable than we ever give them credit for!

      I hope that answers your query.

      I'm happy to answer any more questions you might have!

  5. We are using Petplus for our dog and have been giving him Glucosamine for his joints. Do we still need to give him this alongside the Petplus

    1. Thanks for your comment Robert.
      There are no hard and fast rules because every dog's situation is different. So, have you noticed a marked improvement since you started the glucosamine? If not, then it's probably not worth continuing. For most dogs, there is no need for anything other than Pet Plus as a supplement.
      To see if your dog needs the glucosamine, you could try a few weeks without it and see what happens. If you notice any negative change, start the glucosamine again immediately! If there is no negative change, he probably doesn't need it.
      I hope that helps.

  6. Does this have any inactive ingredients in? I need to give my dog 30mg coq10 a day - would it possible to use this supplement to dose that?

    1. No, there are no inactive ingredients in Pet Plus.
      There are also no limits on how much you can give because there are no toxic or chemical ingredients.
      It contains 40mg CoQ10 per teaspoon
      To supply 30 mg CoQ10 you need to give 3/4 teaspoon daily. It would be fine to give 1 tsp daily. Better too much than too little!

  7. What nutrients and minerals do your supplement have in them and how do they work to help balance a raw diet?

    1. Thanks for your enquiry Eve. Sorry for the delayed response. I have almost completed my house move and apologize for not replying earlier. I now have internet in my Colombian Rainforest home!!!
      You will no doubt have read the list of ingredients and explanation of why each on e is in there on my web site.
      Being a whole food supplement, all the minerals, vitamins, antioxidants etc that nature provides in every mouthful of all raw whole foods are present and bioavailable.
      They balance a raw food diet by ensuring the whole range of micro-nutrients is present at every meal. This includes the probiotics, prebiotics, EFAs and also the digestive enzymes which help to augment the enzymes present in the raw food.
      I hope that answers your question. I have written an article on exactly this topic which I hope you can find on my web site!
      Let me know if you have further questions.

  8. Hi,
    I have two fussy Lhasa Apsos with borderline pancreatitis. I am going to try a homemade diet for them. I know I need to add some additional vitamins to their diet. Does pet plus supply everything they need in this respect or do I still need to add other vitamins? I don’t want to overdo it either. Thanks Diane

    1. Hi Diane,
      I hope I replied to you already, but just at the moment you emailed, I was moving house and I didn't reply on the web site as I should have.
      Yes, Pet Plus has everything in it for them. Best diet would be raw as pancreatitis is caused largely be being fed a diet deficient in enzymes. This would include a home made cooked diet or any of the processed wet or dry 'foods'.
      I'd suggest adding Pet Plus to everything they eat, however frequently you choose to feed them. This will ensure their digestive system and pancreas can cope with digesting the food.
      Let me know how you get on.

  9. Hi! My cat has digestive issues (wind, vomiting, poo dropping from her behind without realising it sometimes and weight loss). Has been checked by a vet. Nothing obvious found though no blood tests. I think she vomits more than other cats partly because she cant eat grass - no teeth! I see her trying to catch hold of it and she cant.
    I am transitioning her to raw food by adding raw mince or chicken thigh to her processed food. She will eat the mince, but not the chicken thigh. She also has only about 4 or 5 teeth due to Forls. She is 7 years old.
    Your supplement sounds ideal- can you advise what else to do to get her to eat raw, and how to introduce bones? (seeing as she has few teeth) or can I stick to just mince? I read they need calcium from bones to digest raw meat - is that correct?

    1. Hi Debbie,
      Most of the pet minces are meat and bone, so I'd suggest you use those. Try all the different sources, so chicken, rabbit, lamb, fish. She needs enzymes to help her digest her food properly, probiotics to stop the fermentation that's going on in her large bowel and producing the wind, prebiotics to support the probiotics.....basically, everything that's in Pet Plus!
      Sounds like you're doing a great job! Gradually wean her off the processed food and her whole digestive system and health will improve. Avoid all chemicals etc as I've suggested elsewhere on this site.
      I hope that answers your question! If not, please do ask more!

      1. I'd also like to add, in answer to this question of yours
        'I read they need calcium from bones to digest raw meat - is that correct?'
        The reason they need to eat bones as well as meat, tripe, offal and organ meats is to balance the minerals, not really anything to do with the actual digestive process.
        If they eat just meat, they end up with too much phosphorous and not enough calcium and other minerals.
        Everything in nature is balanced, so in nature, a carnivore would eat the entire carcass of its prey and thus ingest a beautiful balance of all the minerals and other nutrients and micro-nutrients required to maintain health.
