My rottweiler-german shepherd mix has dandruff problems like you wouldn't believe. And since he's all black you can SEE IT. I got this as my first attempt to quell that, and it's worked like a charm. Discovering he's allergic to beef and switching his diet helped too, but when I tried to change shampoos away from this, the dandruff came back again (just not as bad). It smells wonderful and clears up the dandruff no problem!
