Normally, I would have waited a bit before offering feedback - but this product is nothing short of a miracle. My 8 month old Golden Retriever was diagnosed with severe hip dysplasia - with all the heart breaking side effects. We tried everything - including pain killers. Nothing worked. In two days, this supplement has got the little guy back back on his feet, hungry again and running around shredding every piece of paper he can find. I don't understand the mechanics of a supplement working wonders like this - but if you have a dog with this disorder, try giving him this before operating on him. Drools rules!
