Dr Guenther (Conni) studied veterinary medicine in Gießen, Germany. After qualifying as a vet Conni worked in a practice for several years and in parallel began working for the Interquell Company. Conni built up the Happy Dog and Happy Cat service department. In addition to advising and supporting breeders, her main task was also to help develop new recipes. Conni has been working there for 25 years now and is in the comfortable situation where she can concentrate on her favourite interests: product development, calculations of individual rations and breeding.
