Over the 4 week period, I have noticed a distinct improvement in my 14-year-old dog's mobility, particularly in the morning. He is less stiff in his back legs and seems much happier in himself. The tablets are small and initially, I did hide it in his food or within a small amount of peanut butter as he has never taken any meds for me in the past. However, he does take these directly as if it is a treat and without testing myself I have to assume they smell and taste good. I highly recommend Antinol to pet owners and feel that it is a worthwhile supplement to invest in.
