What? I’m not familiar with either of these Facebook groups (I actually don’t have a Facebook) but I can’t understand why someone wouldn’t be in support of natural supplements for an elderly dog with arthritis? Many glucosamine and chondroitin supplements are actually animal-derived (usually shellfish, shark or bovine or chicken cartilage). There are also many “animal” based supplements such as green lipped mussel, sea cucumber and velvet antler that have been proven effective. I still don’t, however, see why any one would be opposed to a plant-derived supplement either. It’s true that raw diets are high in naturally occurring GAG’s but some dogs with orthopedic issues need more than that and anti-inflammatories can help a lot in many cases.
