Organic Fermented Gut Extract

GUTOMIZER is a fermented herbal extract as a feed supplement for dogs of all ages, which is given daily with the feed. The aim of feeding is a stable intestinal flora, which helps to improve the animal’s well-being and maintain its health.

The GUTOMIZER contains naturally occurring enzymes, vitamins, antioxidants, and trace elements, all of which are essential for optimal health. It also contains lactic acid. Although there is a misconception of the effects of lactic acid on the body, it is a good energy source and helps the digestion of animal tissue. It is involved in preventing degradation processes that arise from microbial changes in the environment in the intestine that can cause digestive problems.

A good intestinal environment leads to better feed conversion through balanced digestive processes. It is crucial for a strong intestinal mucosa, which protects the organism from pathogens and toxins and also prevents excessive infestation with intestinal parasites.

Benefits that go beyond a healthy diet

Glossy coat
& skin

Appropriately balanced ratio of omega fatty acid to keep inflammation down and ensuring a thick, soft, luxurious coat as well as preventing dry and flaky skin.

Gut health
& digestion

Highly digestible bio available nutrients , no fillers, no starch and low carbs all contribute to superior gut health and small well formed stools.

& intolerances

Organic and wild-sourced proteins free of preservatives, additives or anything synthetic helps reduce or even eliminate food-related intolerances or allergies.


A biologically appropriate diet with low carbohydrates and zero starch helps reset a dogs metabolism allowing for better nutrient absorption and improving weight management.


Zero starch means it cannot stick to the teeth and cause plaque and tartar formation combined with naturally occurring enzymes to help protect the teeth and gums.

One sure way to keep your dog happy is by feeding them well with the appropriate food and quantities. Offering your dog insufficient food portions may result in unwanted weight loss and potential nutritional inadequacies. However, providing too much food also comes with a few health disadvantages, with being overweight/obese as the most obvious one. Some of the health issues caused

Our mini poodle had digestive problems and unsettled stomach sometimes. It is difficult to know if t is this or the new food from Rocketo that has settled his stomach so well, but I expect combination of the two. He’s now a really happy pup. No more tummy troubles.

Mr T has had a massive improvement in his tummy after being on this for about a month. Just a tiny bit needed per day, it helps his bowels move more smoothly and they are so much more healthy. Extra poos came at first (still healthy ones) so I assume it is helping him clear out any excess down there too. He barely gets bad breath or smelly dog smell any more either - used in combination with the chicken/beef raw food AND the wild boar/venison which he also loves!

I was looking for a probiotic style supplement for my dogs, particularly as one has had some trouble gaining weight recently so I wanted to boost all their health. Dogs seem happy on this. Only gripe was it was very difficult to pour when the bottle was full - it kept dribbling down the bottle and making a mess of my counter!

I have been adding this product to my dogs Rocketo food. Carlos was diagnosed with chronic colitis and it is practically all I have thought about for the past nine months or so. During this time we have tried many different diets (prescribed kibble, home cooked, bone broth, organic frozen) together with prescribed medication. Absolutley nothing has helped until now until I discovered Rocketo . We switched two weeks ago for both dogs and, dare I say it, there has been two days without blood in Carlos' healthy formed stools. Way Hay!!! I am praying we have cracked it. I will tell my vet all about it once we have had another few clear days - a much better alternative to medication as a treatment for colitis. My other dog Queenie has Addisons Disease so she too will benefit from an imporved diet. We are happy...

My dachshund mix rescue has a super sensitive stomach and liquidy poo. We usually get some tablets from the vet for that but it's always just a temporary fix. Gutomizer has improved his tummy problems immensely. Recommended it to everyone I know. Honestly, did not expect it to do much but I am so happy I decided to try it on a whim.


frequently asked question

In today’s modern world, many people have lost touch with what ‘real’ food is and how important it is to health and wellbeing. This applies equally to us and our dogs. It is a sad reality that humans are the only species on the planet that has lost the ability to feed themselves healthily (Bill Tara, Eating As If All LIfe Matters), but what may be even sadder is that humans make all the decisions on behalf of their dogs, including what and when they eat. Read More

A lot of enzymes, vitamins and minerals, especially vitamins, are really sensitive to heat. Since we keep the heat in all stages of the process below 40 degrees, we avoid vitamins and amino acids changing their form. By keeping the food in its original form, the intestinal tract and microbiome of the dog can recognise, absorb and utilise all the nutrients. This means that all the goodness is available to the dog, and the dogs digestive system and organs don’t have to overwork to access these. Read More

As a civilisation, we have overused our land. The food produced therefore is not only nutritionally deprived, meaning that it lacks essential minerals, but also it can come with unwanted toxins, such as glyphosate, growth factors, antibiotics to name but a few. We try to avoid all of these, as they can cause harm in the dogs body. This is why we only use certified organic products, or wild produced ingredients where they are again away from chemicals used in their production. Read More

Most of our customers are passionate about helping the environment, and so are we. How does our food, and the way we produce it, help the environment? We are passionate about our beautiful planet, and all that lives on it. Because our food is dehydrated with air, it does not ned to be frozen after production, in transport or when with the customer. This has huge energy savings at each stage of the foods journey. It also makes it much more convenient and cost effective for the owner to store at home., It can be treated like any dry food, just kept away from heat, damp and light sources, and just adding fresh warm water (from the kettle not the hot tap!) before feeding to give the perfect water levels for health.

Feeding puppies is an exciting and important time for all animal parents! Giving your puppy the best possible start in life will affect their long term physical and emotional health. This guide is a basic introduction to some key points, and is not intended to be a comprehensive guide to everything needed for feeding puppies. It will tell you why and how Rocketo can be an important part of your puppies diet, and how to use it. Read More
Why is this important to dogs? Although humans are really efficient at digesting carbohydrates, most of the dogs are not. As dogs evolved from a common ancestor with wolves, they also evolved to digest some of the starch and sugars, but that doesn’t mean they thrive on it – there is a BIG difference between thriving and surviving. The only carbohydrates that a dog would eat in the wild are those that are already partially digested in the stomach and gut of their prey, and some grazing on fruits and vegetation when needed. Alas most modern dog foods are highly processed and many contain very high levels of carbohydrates. Read More
