Brewster (4 pound poodle) has been on Clavamox for a gum infection/bacteria for months. He takes the antibiotic for 10 days and smell and yellow goo clears up. Then 8-10 days the smell and yellow goo come back. Dental Cleaning and Blood work (kidney & Liver)are all good. Is there any natural/herbal or over the counter treatment I can give him to clear it up or give to make it longer in between giving the Clavamox? Please advise.
