Even a balanced diet may not meet all your dog’s needs. Supplements can improve joint mobility, skin and coat health, digestion, and immunity. This section reviews top options—glucosamine for joints, omega-3s for skin and coat, probiotics for digestion, and multivitamins for overall wellness. Each guide compares trusted brands, dosages, safety, and vet recommendations to help you choose confidently. Large breeds, seniors, and active dogs often benefit most. The right supplement can enhance your dog’s health, vitality, and longevity. For nutrition-focused care, visit our Special Diets section.
