Owners often search for the best supplements for senior dogs longevity when they notice a quieter dog: slower on stairs, less eager to jump, or more hesitant on slick floors. These changes can reflect joint comfort, muscle strength, and confidence—factors that interact. A supplement can be a reasonable part of the plan, but it should sit alongside traction, appropriate exercise, and veterinary assessment when needed.
Be wary of products that imply guaranteed outcomes. The effectiveness of vitamin-mineral supplements in promoting longevity and vitality is not assured, and quality can be uneven (RVA, 2021). A better standard is whether the product is safe, consistent, and aligned with your dog’s specific constraints.
