It`s worked like a charm! My little 12 year old Brussels Griffon, Elvira had recurring ear infections for months. Even after changing her diet to grain free she was miserable. We`d go to the vet get steroid salves and oral meds for her and they`d clear up, but came back soon after stopping treatment. This mixture doesn`t hurt her, and cleared her up in 3 days! The once a week preventative doses keep her ears clean and pink as they should be. I also have a few hints for all y`all. I warmed up all of the closed tubes, by putting them in a glass of very warm water before mixing them. It helped a lot with making sure that I was able to mix it thoroughly. I also used an insulin syringe with no needle to suck it up into and put it into her ears without getting goop all over. Elvira and I thank you!!!
