We feed the rings on our almost annual Leonberger dog on the recommendation of the breeder, the long-standing positive experience with Vollmer has and it swears. Since Leonberger grow so super fast, a good feed us was really important and I have occupied myself intensively with the topic and quasi "chewed" diverse foods including production and ingredients. The meat content of Vollmers- fodder is very high, it is carefully processed, is high quality and without preservatives and animal experiments. Other feed companies would from these facts probably tinker a huge advertising campaign. The website of Vollmer is little modern but very informative, if you want to know further details, which she had recommended. There are also grain-free foods from Vollmer (ZB Holistic and anitallergie, we also feed), but the Junior rings are not included. Our young dog tolerates the food but very good, looks great and is healthy.
