One of the most common questions pet owners face is if they should be using supplementation for their puppy, adult, or senior dogs. There are many dog supplements available on the market right now, so it’s important to know which marketing claims truly have evidence-based science to back up their claims.

Regulation is still on the horizon when it comes to dog supplementation, but despite this it’s currently a billion-dollar market. The sheer variety of supplements is enough to confuse any pet owner.

However, you should know that many of the active ingredients in dog supplements also overlap with health and nutrition needs for humans. So the evidence for the most popular dog supplements is pretty strong right now.
