Joint supplements for dogs with arthritis and mobility issues are widely used with variable evidence of efficacy, and understanding the evidence helps owners make welfare-focused decisions.
Joint supplement decisions for arthritic dogs are welfare-significant because choosing ineffective products may delay or replace treatments with stronger evidence. The landscape is confusing — many products make marketing claims unsupported by trial evidence. The most welfare-consistent approach combines veterinary assessment with evidence-based interventions: fish oil supplementation has meaningful evidence, weight management is critical, NSAIDs provide documented pain relief, and hydrotherapy improves function. These should be the foundation before adding supplements with weaker evidence. The goal is reducing pain and maintaining mobility through the most effective interventions available.
