My dog has moderate hip dysplasia. In the past I was using a senior food (she's 11) that contains glucosamine, but I wanted to switch her to a food without fish, as she seems to have a sensitivity to it. I ended up switching her to a non-senior food, which means there's no glucosamine anymore. I had tried a powder form, but it smelled really bad and made her breath horrible. I came across this one in my research online, so decided to give it a try. She loves the taste, the smell is sweet and doesn't affect her breath, and it seems to be lasting as long as the powder - but at a lower price. WIN-WIN-WIN!
