The story of DOG FIT by PreThis®
Close to nature – from the beginning
Over 22 years ago, our then Miniature Pinscher was diagnosed with osteoarthritis and spondylosis. By specifically supplementing his daily diet with natural micronutrients, his general condition improved noticeably – a turning point that led to the creation of DOG FIT by PreThis®.
Our nature-loving family comes from Andorra – a small principality in the Pyrenees with the highest life expectancy in Europe and excellent water quality. This special place is the home of our PURIDAL corporate headquarters. Since merging with the established PreThis® brand, our products have been available in over 50 countries worldwide for over 20 years.
Developed with the Power of Nature
Nature is our daily inspiration and the basis of our product development. Our goal was and remains to create functional supplementary food for dogs – as part of a conscious, species-appropriate diet. We consistently avoid artificial additives and use only high-quality, natural raw materials of proven quality.
Our product line was born out of the desire to meaningfully combine the knowledge of veterinary medicine, Traditional Chinese Medicine (TCM), Traditional African Medicine (TAM), the Indian natural science of Ayurveda, herbal and fungal medicine, and modern nutritional research – with a focus on natural ingredients, high tolerance, and many years of experience.
From dog owners for dog owners
We have kept dogs ourselves for many years, as well as cats and horses. Our personal passion has become a daily task, which we pursue with passion together with a team of experts including veterinarians, animal health practitioners, canine physiotherapists, nutritionists, and herbal and fungal experts.
Our products are free from:
- artificial flavors, colors, and preservatives
- industrial sugar, grains, gluten, soy, fructose, yeast
- palm oil and other non-resource-saving ingredients
- genetic engineering (GMO) and animal testing
- magnesium stearate as a filler
- synthetic capsule shells
- common allergens
- unnecessary or hidden additives

Together for a sustainable future
Sustainability is not a trend for us, but a lived responsibility. We use green electricity in production and in the office; our climate-neutral shipping center utilizes a large-scale photovoltaic system and modern rainwater retention basins. Our new stand-up pouches are 100% recyclable, and our print media are produced in a climate-neutral manner.
In addition, we support certified climate protection projects – e.g., to protect the oceans – and offset the CO2 emissions of our promotional materials. With every order, our customers can voluntarily make a small contribution, which also goes towards these projects.
