I think most people go overboard with too many unnecessary supplements. If your dog is on a complete and balanced food there is no need for supplements unless you want something for a specific problem.
Extra Omega 3’s are great for skin, joint, and heart health. It is a good overall supplement but I prefer to just feed my dog real mackerel or sardines as opposed to a fish oil supplement. It is cheaper and fresh food is always a good thing.
Glucosamine, chondroitin, msm, green lipped mussel powder are all great for arthritis. CBD oil I find is even better
Coq10 can be great for heart health if your dog has any problems with that
As you can see, most supplements are good for specific issues and do not need to be given just because.
