Is the Marengo allergy concept tried and tested, and if “yes”, for how long already?

The Marengo allergy concept has already been known since 1993 as Marengo, but it has been used successfully since 1989. It was developed within the context of alternative, veterinary treatments and for this reason probably displays the successful combination of theory and practice. Apart from the fact that Marengo is finding more and more fans, a look at the 'My Marengo Dog' web-pages of our homepage can provide you with a small impression of the success.
