Joint supplements for dogs vary substantially in evidence quality, and evidence-based selection supports welfare by providing genuine pain relief rather than false comfort.
Dog joint supplement decisions directly affect welfare by determining whether arthritic dogs receive genuine pain relief or false comfort from ineffective products. Evidence-based supplement selection — prioritizing omega-3 fatty acids and green-lipped mussel with reasonable evidence over products with weak evidence — provides better welfare outcomes. The welfare risk of relying on supplements instead of proven pain medication for dogs with significant arthritis is that these dogs live with undertreated pain while owners believe they are receiving help. Supplements are most valuable as adjuncts to proven veterinary pain management rather than as primary treatment for dogs with moderate to severe arthritis.
