FAQs
When should I start joint supplements for my dog?
Large and giant breeds benefit from preventive glucosamine supplementation from as young as 12-18 months, before signs of arthritis appear. For any dog showing stiffness, difficulty rising, or reluctance to exercise, start therapeutic-dose supplementation and schedule a vet exam to assess joint health.
Are human glucosamine supplements safe for dogs?
Plain glucosamine HCl or glucosamine sulfate human supplements are generally safe for dogs. However, avoid formulations containing xylitol (toxic to dogs) or NSAIDs. Dog-specific products like Cosequin and Dasuquin are formulated with canine-appropriate dosing and combinations and are the safest, most convenient option.
