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.


We only use fresh ingredients sourced from organic and ethically wild suppliers for the cleanest product and optimal health.

My dog absolutely loves these they make the perfect treat also love that they come in a big bag! But why have you changed the fat content it used to be just around 2 or 3% now it’s over 20%? My dog has pancreatitis so unfortunately I won’t be able to repurchase these for him again, such a shame!

As soon as I opened the packet of these I knew they were good. First off, they look like a fresh fish, which is what they are, just dehydrated! they smell fresh (unlike some stinky sprat treats from other brands) and I just know they are doing my dog good, as well as being a delicious and much enjoyed treat. Both human and dog are happy. I highly recommend these Comets. The photo shows my dog exercising a lot of patience whilst waiting for one!

My little Jacqou at age 4-5 months was such a picky eater. I had to restrain from hand-feeding him! Come to find out he LOVES the fishy comets. I take one at every meal and break it into small pieces and mix it with his minced complete raw. I then promptly wash my hands, lol. I am afraid of using Omega-3 fish oil because it has a tendency to soften his stools, so this is perfect.

Totally Arto's favourite treat - he will do absolutely anything for a fishy comet. In fact, he has learnt the words 'fishy comet' now and his ears perk up!!! We have a bag under the sink and each time we open the door he rushes over. The hard part has been teaching him to take them softly out of our hands rather than snatching!!

Great low calorie high value (aka smelly and delicious) treats for our Jack-Chi! Easy to break into smaller pieces if needed or can be given as a whole thing to crunch away as a special treat. They are completely dried so if you don't mind your pocket smelling a bit funky they're easy to take with you on walks as well!

My dog has a tendency to be a bit overweight so I am pleased to have found these fishy comets to give him as a low fat healthy treat. He absolutely loves them . I dont have to worry about the ingredients because I can see (and smell!) that they are just dried fish. Even the cat has been known to enjoy one on occasion which proves they are a high quality food.

Better than the meteorites, and the crunch as they chomp on them! `They hear the bag - and then there is the thunder of paws as they hurtle (seriously - no control!) to the kitchen. Then they sing, stand on two legs, yip, and once they have them - one remains - because the others scatter to the four winds! Good to know its healthy for them too.

Don't know why I was worried, as everytime I purchase from you my rescued chihuahua loves ❤ to eat

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
