The gut is more than a place for digestion—it is a major point of contact for the immune system, stimulating correct responses for the control of pathogens from the environment that have been consumed. In dogs, their fondness for scavenging material can make them more vulnerable to exposure to disease-causing bacteria (which can then colonize the gut wall, leading to diarrhea and flatulence), but pets also love to go where their owners would prefer they don’t. There are now several products available that have been developed specifically to prevent these problems.
