Direct Fed Micro Organisms also known as Probiotics are actual living organisms that have a positive effect on the intestinal flora where many different bacteria reside. The gastro intestinal tract of your pet (people too, as both are mammals) contains over 400 species of micro organisms.
 
Pet food with probiotics is definitely a good choice when it comes to a holistic pet foods, these good guys block bad bacteria from setting up house in our bodies. Without good bacteria, bodies are less able to fight off disease, adequately absorb food and intestines become overrun with toxins and waste, which set the breeding ground for disease. 
 
Lactobacilli exist in an animals system naturally but are depleted by illness, stress, trauma or ingestion of antibiotics and antifungal medications administered to fight infections. Antibiotic and antifungal medications kill not only disease causing bacteria but also the beneficial lactobacilli present in your pet’s intestine. 

Plain yogurt that has low sugar content is also a rich source of this bacteria and a teaspoonful of yogurt added to your pet’s food is also a good way of naturally supplementing their diet.
