I have noticed in the pet stores they sell brewers yeast for about $30/bottle. Yet when I buy my vitamins the bottles of brewers yeast is less then half the price. Does anyone give there dog brewers yeast? And is there really a difference in the stuff at the pet store apposed to the drugstore? ( I was told it stops the females urine from turning the grass yellow) I have noticed the dead spots in my lawn and want to know what to do to fix/stop it. |
