Nature gives us so much to work with

We only use the finest natural ingredients with excellent bioavailability, sourced from all over the world, from Germany to Japan. When making our DOG FIT by PreThis® products, we place the greatest importance on purity and on processing the ingredients gently. This is the only way we can achieve the above-average quality we promise our customers.

Transparency and honesty matter to us just as much as the quality of our products. Not all natural micronutrients are suitable for use in complementary feed. In some cases, synthetic forms that remain stable over a longer period are needed to ensure quality and bioavailability. These synthetic forms are completely safe and can sometimes even be more readily available than natural alternatives.

But these are the exceptions. Our aim remains to use natural ingredients wherever possible while giving your dog the best possible support.

Join us on the natural path

In the DOG FIT by PreThis® range, we rely on select, carefully tested ingredients with no unwanted additives. The production of our complementary feed for dogs is subject to the strict HACCP ISO 9001 standards. Regular quality checks by independent laboratories guarantee the consistently high quality of our ingredients.

We take our responsibility towards you, your four-legged friend and our planet seriously. That is why, wherever possible, we use raw materials from sustainable cultivation and responsible farming to protect natural resources.

Our products are entirely free from animal testing, gluten, fructose, grain, yeast, soya, palm oil, artificial flavourings and preservatives. We also do without magnesium stearate altogether.

Our ingredients are constantly monitored

To ensure the highest quality of our products, the raw materials undergo rigorous quality control. Every single ingredient is regularly tested for purity, because an uncompromising quality standard is of the utmost importance to us.

To this end, our raw material suppliers carry out regular series of tests, which also cover the finished products. These testing procedures are based on the latest scientific findings and draw on the experience gained from extensive research. This care ensures that our complementary feed for dogs meets the highest standards.

Many years of intensive investment have gone into optimising the production processes. Thanks to state-of-the-art processing technology, the valuable ingredients in our products can be processed gently and retain their high quality.

Experience and research pay off

Our complementary feed is developed on the basis of years of research in collaboration with vets, animal health practitioners, animal physiotherapists, herbal experts, mycotherapists and nutritionists. As a dog's vitality is influenced by many factors, we continuously analyse which micronutrients make sense in a dosage and composition tailored to their needs.

Only when supplements are optimally matched to a dog's actual needs can the body make the best possible use of them. That is why we do our very best every day to support dogs' nutrient supply with high-quality ingredients and so make a valuable contribution to their general wellbeing.

Naturally fit with DOG FIT

Drawing on many years of experience and working with qualified experts, we have developed the DOG FIT by PreThis® nutrient system, with the aim of supporting a dog's needs-based nutrient supply as well as possible.

Over the course of a dog's life, various factors such as breed, breeding, strain, diet, genetics, injuries and age can affect its vitality. DOG FIT by PreThis® offers high-quality complementary feed that supports dogs according to their needs at every stage of life, in everyday life as well as in particularly demanding situations.

For more than 25 years, DOG FIT by PreThis® has been developing high-quality complementary feed together with animal health practitioners and vets, always with high standards of quality and purity.

But we are not resting on our laurels. Our research continues, because we want to keep improving the needs-based nutrient supply of dogs. Every day we work on developing our products further and giving our four-legged friends the best possible support.
