I have already purchased this Supplement to 2 times. My dog accepts it and there's all drinne what needs such a dietary supplement. Dazubekommt my dog eggshell flour and occasionally Spirulina otherwise the usual oils, fruits / vegetables, meat, bones, nuts etc. My dog only needs There's always something more to feed than in all possible tables is specified, so it gets a bit more , as indicated by the BARF-Complex. I once read in an other customer reviews to show that someone wrote that the most important is missing and it is taurine. That made me suspicious. because I went to a veterinary practitioner who also also is still healing practitioners and studied herbalism and on top of that also is still a BARF expert who has a Barfladen (highly competent so) and asked him for his opinion about the product. Taurine is sufficient in meat and dogs it need not get fed extra (like cats), because taurine also is not responsible for any processes of the eye, it can happen that dogs too much taurine can also blind. He also sent this product to a laboratory and examine whether really well which is inside, what is it and if there is not also something else inside. The result of the laboratory is turned out well for the product and he recorded it himself in his shop range. PS: He also has his own flesh (slaughterhouse waste, not bled) can check by the laboratory. Everything is as it should be and it has approved the powder. My man of confidence !! So I can not conscience Refer also quiet.
