Like us humans, pets, especially dogs, have a gut lining that keeps bacteria, toxins, and allergens out.
However, a dog's gut is more sensitive due to their diet and environmental exposure, making them more prone to having Leaky Gut Syndrome.
Leaky Gut Syndrome is a condition caused by overgrowth of bad bacteria damaging the gut wall, creating gaps allowing toxins and allergens to leak into the bloodstream, leading to weak immune system, making dogs vulnerable and easily exposed to Parvovirus resulting in fatal sickness.
