My 6-year-old female Corgi/Chihuahua mix, Qaisuke, was diagnosed with hip dysplasia and resulting osteoarthritis in both her hips. She has been taking System Saver now for several months (in addition to Nupro Joint Support, wild Alaskan salmon oil, vitamins C and E, and MSM) with her grassfed/organic/wild caught raw meat diet. Prior to adding System Saver to her list of dietary supplements, she had her good days and her bad days and I was carrying her on most of our hiking trips. But since adding System Saver to the lineup, she is a new dog. Any evidence of her joint issues is seen only rarely. No other supplement or vitamin I’ve tried with her has produced as substantial results as System Saver.
