"I have used Vibactra Plus not only to treat Parvo puppies, but for many, many other things as well. Tooth infections, eye infections, wounds, etc.. I always use it after a spay/neuter to prevent infection. If anything seems "off " in one of our dogs, the first thing I reach for is the Vibactra Plus. Running a rescue can bring all sorts of surprises, and Vibactra Plus allows me to jump right on all kinds of things before they get out of hand. It's practically a cure-all, and I wouldn't be with out it. "
