When my male cocker spaniel was about 6 months old, symptoms of hip dysplasia showed up dramatically. In a very short time he was almost crippled. After praying (God is good!),
I began giving him 2,000 mg. of buffered C daily. Within a few days, he was walking & running like a normal pup. When I discontinued the C, the symptoms reoccurred, so I kept him on it continually.
He is 12 years old now, is quite healthy, and still walks/runs without a problem. He has an unusually healthy diet, including apple cider vinegar & other supplements, and he and his twin sister are incredibly young for their age!
