Question Best supplement(s) for preventative back and joint issues?

[SauerDog]

My 3 1/2 yr old male Standard Dachshund is about 30 pounds and very active and healthy. I've been feeding him high quality can and dry food twice a day, along with canine glucosamine/chondroitin and probiotics. He has ramps for getting on my couch and I limit unnecessary jumping from high places etc. No signs of joint or back issues as of yet. Just wondering if there's much more I can do to help stave off the potential IVDD or other joint issues?
