Louis has had Hip Dysplacia since he was just over a year old and about 5 years ago we were recommended Glyco III tablets to help his joints and the arthritis that would eventually come. He started off with one tablet a day and then you give half a tablet a day maintenance dose, he is 10 years old now and is doing really well, he still chases about in the garden, runs along the hall and jumps over anything in his way to get to the treat tin in the kitchen and given half a chance will scoot up the stairs at high speed if he has stolen a sock or something he thinks is a prize possession we might want. He does tend to slow down at night and prefers to be lifted onto the sofa but he can still jump up there when he wants to. We am certain that its the Glyco III that have kept him so active and have recommended them on to others with dogs that have joint problems. Both my two also have a teaspoon of raw organic coconut oil which i believe also help and is great for their coat also
