Introducing Mr. Bones: The origin of raw materials and responsibility in pet food

Time to read 11 min

Why do origin and responsibility matter?

Pet owners nowadays should know what pet food contains and where the raw materials come from. Transparency of origin and responsibility mean better quality, nutrient content, taste, safety, and ethics – just like in our own food shopping. The Mr. Bones pet food brand was born from this idea: "Why wouldn't we prepare food for our four-legged family members with the same care as for ourselves?" The result is honest, delicious, and healthy food for dogs and cats – recipes that not only nourish but also show love. Mr. Bones focuses on traceable raw materials, high quality, and environmental responsibility so that your pet receives the best possible nutrition without guilt.

"From farm to bag" – Mr. Bones' production chain

Mr. Bones' production chain begins in the Spanish countryside and ends with a carefully packed treat bag. Almost all raw materials come from small, reliable farms in the province of Salamanca and the northern part of Extremadura in Spain. In these areas, family farms and dehesa pastures raise animals using traditional methods: for example, deer, wild boars, mouflon sheep, and the famous Iberian black pigs roam freely in oak forests and meadows, living in harmony with their land. As a result, the meat is as ethical and traceable as possible – every raw material has a story and a traceable name.


Fish is an exception, as it is naturally not farmed on pastures. Mr. Bones uses small, wild fish caught from the Atlantic Ocean near the coast of Spain. More precisely, the fish are responsibly sourced from the Cantabrian Sea (Bay of Biscay) in the north and the coast of Huelva in southern Spain. In these coastal areas, local fishermen catch, among others, anchovies and sardines, known for their excellent quality and Omega-3 profile compared to larger fish. The raw materials travel a short distance directly to the production facility, ensuring freshness and reducing the environmental impact of transportation.


The production chain is built with "human grade" as a priority: all Mr. Bones products are made in the same food facilities where human food is produced, following strict quality and traceability standards. Every step from primary production to packaging follows the same care as if the food were for our own plates. This is evident, for example, in that the raw materials are suitable for human consumption and recipes are prepared in small batches, often handcrafted in local "artisan" bakeries, ensuring freshness and excellent taste. No batch leaves the farm bagged without complete quality control and transparent documentation.

Why are game meat and small fish an ecological and good nutritional choice?

Game meat – such as venison, wild boar, or mouflon meat – is naturally nutritious, low-fat, and pure food. The meat of wild animals contains plenty of protein (typically 20–26 g protein / 100 g meat) and very little fat (usually under 5%). Game also naturally has a healthier fatty acid composition: the animals roam freely and eat nature's offerings (such as acorns, berries, and herbs), which raises the Omega-3 content of the meat compared to intensively farmed meat. Additionally, game meat is an excellent source of iron and zinc, and completely free from antibiotics, growth hormones, or artificial additives – wild animals are not fed industrial feed mixes but eat what nature provides. Many also consider the taste of game richer and purer: the flavor varies according to seasons and habitat but is always genuinely meaty and intense. Ethically sourced game also helps the environment – responsible hunting maintains natural balance by preventing overpopulation and reducing the need for environmentally burdensome livestock farming. Each game delicacy thus represents a smaller ecological footprint and respect for nature.

Small fish, such as anchovy, sardine, and mackerel, are another cornerstone of sustainable choice in Mr. Bones' recipes. They reproduce quickly and populations withstand fishing better than large predatory fish, so their fishing is often ecologically more sustainable. Mr. Bones collaborates with local fishermen and ensures that all fish are caught using sustainable methods at the right time and from the right place. For example, anchovies (boquerón) are seasonally caught off the coast of Huelva with small vessels, supporting small community fisheries and reducing unnecessary transport – thus keeping the carbon footprint low. Nutritionally, small fish are true superfoods: anchovy is one of the world's richest fish in omega-3, and it also contains plenty of important vitamins (A, B6, B12, D, E, K) as well as minerals such as iron, calcium, selenium, and zinc. Omega-3 fatty acids support pet skin health and coat shine and act anti-inflammatory for joint well-being. Additionally, small fish are often eaten whole (with bones and skin), meaning the delicacies include natural calcium and other nutrients from the whole animal – nothing goes to waste. All Mr. Bones fish products are 100% fish with no extras, making them excellent also for pets with sensitive stomachs. If you want especially pure and nutritious Omega-3 oil, then sardine oil is an excellent choice.


Together, wild game and small fish form an ecological winning duo: game sustainably utilizes natural resources on land, and small fish do so in the sea. Both are full of flavor and nutrients, so your pet can enjoy treats healthily. At the same time, as an owner, you can trust that your choice is better for the environment and animals – natural food that comes directly from nature.

What does “responsible packaging” mean for Mr. Bones?

Responsibility at Mr. Bones is not limited to the food content alone but also extends to the packaging. The company has taken special measures to ensure that the packaging is as environmentally friendly as possible. In practice, this means that Mr. Bones treats are packed in minimalist, resealable bags containing only the essentials – no unnecessary extra plastic or cardboard materials. The streamlined and functional packaging design effectively protects the product while preserving aromas and freshness, but uses less material and produces less waste. The bags are lightweight to transport and take up little space, which in turn reduces transportation emissions. Many packages are reusable zip bags that can still be used after the treat is finished – for example, you can refill the bag at home from a larger package, which reduces single-use waste.


Mr. Bones emphasizes that environmentally responsible packaging is part of their overall philosophy: just as raw materials are sourced from local producers and manufactured with a small carbon footprint, smart choices are also made in packaging. The packages are recyclable and use environmentally friendly materials whenever possible without compromising shelf life. For the customer, responsible packaging means convenience – the products are packed in handy bags that preserve the treats well without extra freeze dryers or preservatives. When you open a Mr. Bones bag, you can be sure the contents are fresh and high quality, while also knowing the packaging has produced as little environmental impact as possible.

Frequently asked questions about Mr. Bones products

Where do Mr. Bones' raw materials come from?

Mr. Bones sources its raw materials mainly from Spain, from the Salamanca and Extremadura regions. The meats come from local family farms and hunting areas, where animals (such as deer, wild boars, mouflons, and Iberian pigs) live free on natural pastures. Fish are caught from Spanish coastal waters – especially from the Atlantic side, the Cantabrian Sea, and the Huelva coast – in cooperation with sustainable local fishermen. Vegetables and fruits also come from nearby area growers. All raw materials are traceable back to the original farms and fishing areas.

Do Mr. Bones products contain additives or preservatives?

Mr. Bones' philosophy is "short ingredient lists" – meaning the products mainly consist of a single animal protein (monoprotein) and possibly a small amount of natural additives, such as herbs or vegetables. No artificial preservatives, colorings, or flavorings are added at all. The products' shelf life is ensured by a gentle drying method (air drying at low temperature), which removes moisture but preserves nutrients and flavor. This way, the treats remain without chemical preservatives. Everything is as natural as possible – as seen on the label, the ingredient list often has only one line (e.g., "100 % venison" or "100 % anchovy").

How does Mr. Bones ensure the quality and safety of its products?

Quality and safety assurance begins with the careful selection of raw materials: only raw materials suitable for human consumption and reliable, well-known producers are used. The entire production process follows the standards of the human food industry. In fact, Mr. Bones has its products manufactured in factories that also produce food for humans, so quality and hygiene criteria are very high at every stage. Every batch is traceable – the company documents precisely from which farm or waters the raw materials have come, when the product was manufactured and packaged. Additionally, the products are analyzed to ensure nutritional content and purity. Mr. Bones strives for complete transparency: for the customer, this is visible in clear composition information and origin markings on the packaging. You can trust that every treat is safe and high-quality for your pet.

In which country are Mr. Bones products manufactured?

All Mr. Bones products are manufactured in Spain. Product development, manufacturing, and packaging take place in the Extremadura region, close to the raw material production sites. By producing locally, the company can closely monitor every production stage and keep the products' freshness at a top level. The Spanish origin is also reflected in the product names and stories – for example, Iberico pork delicacies come from the oak forests of the Iberian Peninsula, and anchovies from the Cantabrian Sea on the northern coast of Spain. Mentioning the country and place of manufacture is part of Mr. Bones' transparency promise, so every package clearly states "Made in Spain" as a mark of quality.

Why does Mr. Bones use game meat as a raw material?

According to Mr. Bones, game meat is an ecological, ethical, and nutritious raw material. The meat of wild animals is pure – they have not been fed industrial feed nor given antibiotics, so the meat is natural and additive-free. Additionally, game animals have lived a good life free in nature, which aligns with an ethically responsible value system: the animals' welfare has been ensured during their lifetime. The use of game meat utilizes natural resources wisely; for example, in Finland and Spain, a sustainable number of wild boars and deer are hunted annually for population control. Mr. Bones recovers this high-quality protein for pet food instead of letting the meat go to waste. Nutritionally, game meat is excellent: it contains a lot of protein, iron, and vitamins, but only a little fat. Many dogs love the strong taste of game – it is close to the dog's natural diet. Ecologically, utilizing wild game reduces the footprint because emissions from intensive livestock farming, feed cultivation, and long transport distances are avoided. Overall, using game meat as a raw material supports Mr. Bones' goal of offering the most natural and responsible food for pets.

Are Mr. Bones products grain-free and hypoallergenic?

Mr. Bones products are grain-free and contain only one type of animal protein (monoprotein). This simple composition makes them well tolerated even by sensitive dogs and cats. Since the recipes do not contain common allergens such as wheat, corn, or soy, they are suitable for many allergic pets. The absence of additives is also an advantage for sensitive individuals – when there are no unnecessary chemicals, the body is less burdened. However, it is always good to gradually accustom your pet to new food. Mr. Bones' selection also includes completely single-protein treats (such as 100% duck, 100% venison), which many veterinarians recommend for elimination diets to identify allergies. A short ingredient list means you know exactly what your pet is eating and can easily avoid unsuitable raw materials.

Are Mr. Bones products suitable for an elimination diet?

With Mr. Bones products, it is easy to implement a limited elimination diet for your pet if necessary. The products typically contain only one ingredient. You can get food, treats, and snacks from the same protein. If you have already tried everything, why not try mouflon or Iberico black pig?

How does Mr. Bones consider the environment in production?

Environmental responsibility runs as a common thread throughout Mr. Bones' production. The locality and responsibility of raw materials, small fishing vessels, the utilization of wild game, and a short production chain are all environmental actions – they minimize transport emissions, emissions caused by intensive production, and the waste of natural resources. Additionally, the packaging is designed with the environment in mind: minimalist packaging design reduces waste, and the packages are recyclable. Manufacturing facilities are located close to the raw materials, which means less back-and-forth transportation. Mr. Bones has also stated that it continuously works to find new ways to reduce its carbon footprint – for example, by considering renewable energy sources in production and logistics. When you buy Mr. Bones, you thus support a company that takes the environment into account at every stage.

How can I know that a Mr. Bones product is exactly what it promises?

Mr. Bones emphasizes full transparency. Each package has a clear product description where you can see the ingredients (usually only one main raw material) and nutritional content. Many products are literally what the name says – e.g., 100% dried deer heart contains only air-dried deer heart, nothing else. The company uses the slogan “Made of Extremadura” to assure that the products genuinely come from where they claim. Thanks to the traceability system, they can precisely tell from which raw material batch a particular product was made. If the package says “Iberian possum ear,” it really comes from a free-range Iberian pig in Extremadura. You can trust that the product is authentic and of the quality it promises – and Mr. Bones' reputation in the market supports this (the brand has received praise for its transparency and the visible quality of its products).

Do Mr. Bones products have other benefits for my pet?

Yes, many! Firstly, health benefits: because the raw materials are of high quality (e.g., wild game, small fish, green-lipped mussel) and processing is minimal, important nutrients are preserved in the products. For example, Mr. Bones' green-lipped mussel powder is a natural support for joint health (green-lipped mussel contains glucosamine, chondroitin, and omega-3 ETA fatty acid, which support joint function). Dried liver and heart treats, on the other hand, are vitamin-rich rewards. Secondly, palatability: many pet owners notice that their dogs and cats love Mr. Bones treats – the natural meaty aroma and taste stimulate even the pickiest pet's appetite. Thirdly, dental health: air-dried meat and fish pieces are crunchy, which helps keep teeth clean (chewing reduces plaque buildup). Additionally, the versatility of the products is an advantage – you can give pieces as a reward during training, in interactive toys, or as an appetite enhancer mixed with complete food (by crumbling the treat over the food). All these benefits come without concern for extra fillers or additives. So, it is a treat that brings joy to both the pet and the owner!
