This product really works. My dog is arthritic, stumbling using steps, loosing footing when trying to turn sharply etc. She had been on a prescription through the Vet, it was working but costly. I changed to the BIOBALANCE Glucosamine and she doesn\'t have any issues at all with her arthritis. She manages to now get in and out of the car easily. My son feeds the dogs sometimes and I actually no when he hasn\'t given the Glucosamine, it shows quite quickly. Currently the powder is a bit lumpy, but I just squash it with a spoon, its a bit like icing sugar, my dog has no trouble taking it. I spoon it over her wet and dry food, then give it a quick stir.
