P&G Pet Care has introduced prebiotic petfood formulas of Iams and Eukanuba to help maintain pets' gastrointestinal health. Featuring the prebiotic FOS (fructooligosaccharides), these new formulas stimulate the balance of gut microflora (species of good bacteria) which in turn promotes a stronger immune system to help fight disease, according to P&G.

"There has been an explosion of new prebiotic and probiotic products in human nutrition and … consumers are embracing these products to help promote their own digestive and overall health," said Dr. Sherry Sanderson, animal nutrition expert and associate professor at the University of Georgia College of Veterinary Medicine.
