I was skeptical about another "product" saying it would fix things but I figured she was worth the investment. After one week, the odor from her skin was gone. After two to three weeks, the constant chewing and scratching stopped, and after a month, her skin and coat are very healthy, and now after two months, I'm only maintaining healthy ears (cleaning them one time a week). She even jumps on the sofa now! That was the most pleasant surprise! She is between 12-14 years of age and one day she scared me when she jumped up next to me on the sofa!
