Can my allergy-suffering dog eat the Marengo herb cookies without any concern?

Yes. The Marengo Wellness-Bits have already been successfully used for many years within the context of the 63-day Marengo diet, and they supply important nutritional building blocks for the skin and intestinal flora.
The herb-mixture consists of selected, additive-free and high-quality herbs that are well-tolerated as a pure dietary supplement. Only if a primary allergy exists against a specific herb contained in the mixture, should this be avoided. Please bear in mind that, also with a positive allergy test to a specific herb, this generally refers to a secondary allergy. In this case, one can still feed this without any problems. Especially in cases of a secondary allergy, the feeding can provide a significant contribution to desensitization.
