I'll tell ya what.....I used it EVERY day year around and had NOOOOOOO flea problems whatsoever. THEN......I ran out of the tablets. Couldn't get more for about 2 weeks or so. The darned fleas jumped on my beloved dogs and drove them crazy
. Not infested, but one flea is too many
! Now that they are flea free from having to do a treatment (which I wanted to avoid), I will start them back on the Brewer's Yeast and HOPE not to ever have give them a "treatment" again.
In addition, that is a 8-in-one pill.....good for the skin, coat, etc. I give it
