Cruz is just starting his second tub of the Hip and Joint and it does seem to have made a noticeable difference to his wellbeing. He will be ten in October and as large breed dog has developed some arthritis, which he is on medication for. However, I wanted to try something extra and since he has been on the Hip and Joint, he has become even more active and playful and he is less stiff in the evenings, despite the cold weather. It does seem to have put an extra bounce in his step.
