We succeeded by discovering certain effects of different types of algae and plants. Their special combination is able to soften tartar and prevent new plaque build-up. DOG FIT by PreThis® WHITE dental is simply added to the food as granules. It could hardly be easier and less stressful for the dog and owner to ensure whiter and healthier teeth.

Bad breath, gingivitis and problems with the gastrointestinal tract unfortunately occur in many dogs from time to time in the course of their lives. The causes are manifold, but are usually triggered by a bacterial infestation in the mouth and throat area. Our task was to tackle the causes and not just to cover up the symptoms. So, in close cooperation with veterinary practitioners and herbal experts, we developed DOG FIT by PreThis® FRESH. 16 herbs plus black cumin meal proved to be very suitable for sustainably combating bad breath, alleviating inflammation and also rebalancing the digestion due to their antibacterial and oral flora rebalancing properties. DOG FIT by PreThis® FRESH is purely natural, vegan and very well tolerated. Pure nature!
