What supplements actually work for your dog? Need recommendations

Hey everyone,

My dog is getting older (7 years now) and I want to start him on some supplements.

Mainly looking for:

• Joint health (he's slowing down on walks)

• Coat and skin (gets dry sometimes)

• Overall energy

But honestly, I'm confused. There's SO many options online.

What supplements do you actually give your dog that work? Not the expensive marketing stuff - what actually helped your dog?

Would really appreciate real experiences.
