How much brewer's yeast do you take, and internally, right? ThanksReplied By Westwind (Orlando, Fl) on 05/03/2010
Brewer's Yeast works! I started using it early last spring, throughout the summer and into early winter. I never saw a flea on my Bassett Hound. I had my doubts living in a humid, hot climate where fleas thrive, but I never saw even 1 flea. I put about a teaspoon on her food at night (she's a small bassett, about 40 lbs). She loves the taste! Brewer's Yeast is natural and filled with other nutritional stuff your dog needs. Give it a try!
