Clinically Proven Prebiotics
Support a Dog’s Strong Defenses

Did you know almost 70% of your dog’s immune system is found in the digestive tract? Eukanuba’s Prebiotic, FOS (fructooligosaccharides), aids in digestive health by promoting the growth of good bacteria and in the process reduces bad bacteria.

The digestive tract acts as a guardian for the rest of the dog’s body. For this reason, FOS is now in the majority of our formulas.* By striking the right balance between good and bad bacteria, FOS helps promote strong defenses.
