I think they're probably safe to give him, altho you might want to talk to your vet about it. They're made up of glucosamine and chondroitin, humans also take them for arthritis problems. I know of some people who give them to dogs as a preventive, altho I don't know if they work as a preventive. I actually took some for my oncoming arthitis in a knee once and they didn't help at all, so I stopped taking them.
I have never given them to a dog as a preventive, I did feed one senior dog a senior kibble formula that had glucosamine and chondroitin in it. He went on to have significant joint problems, so I can't conclude anything from that.
In general, my opinion is, pending a talk with your vet, that they're probalby okay to give him, but he probably doesn't need them, since he's a young dog with no sign of joint problems.
