Every joint supplement has failed my dog — what is left?

Five years of trying and nothing has worked — that's exhausting, and I want to give you an honest answer rather than sell you another supplement. Before I say anything else: has the vet done recent imaging? The question isn't whether the supplements failed — it's whether the arthritis has progressed to a stage where supplements were never going to be enough.

Moderate-to-severe, 18 months ago, and she's not managing well — that's the picture. I'm not going to recommend a supplement here. The right conversation is with the vet about Librela. It's a monthly monoclonal antibody injection that blocks pain at the nerve level in a way no supplement approaches. It's specifically approved for dogs in exactly this situation — established OA where the supplement window has closed. I know that's not the answer you came for, but the honest answer is that another supplement will not be the thing that helps her now. Librela may be.
