Value of Probiotics in Canine and Feline Gastroenterology

Probiotics/or synbiotics products for small animals do not fulfill the criteria required to qualify as a probiotic. Studies explaining modes of action are lacking. Outcome measures are inconsistent, with some trials assessing only nonspecific routine diagnostic parameters or fecal scores. Preliminary evidence shows that specific preparations are beneficial in parvovirus infections and acute hemorrhagic diarrhea syndrome in dogs and in Tritrichomonas fetus infection in cats. In dogs, inflammatory bowel disease specific probiotics can decrease clinical severity. More studies focusing on functional outcomes in dogs and cats with well-defined diseases to allow evidence-based clinical use of probiotics and synbiotics are needed.
