For dog owners, diarrhea just comes with the territory and seeing a beloved pet in gastrointestinal distress can be awful for our noses and emotions. New research from the United Kingdom’s Royal Veterinary College also indicates that some dog breeds may be more susceptible. Out of two million dogs studied, six breeds appear to be more likely to be diagnosed with diarrhea, according to a study published June 11 in the open-access journal PLOS One. “Many cases of diarrhea in dogs and cats are mild and self-limiting,” Cornell University veterinarian Dr. Meredith Miller says. However, the authors also found that around 38 percent of all diarrhea cases were treated with antibiotics, despite the recommendations against using antibiotics in dogs with mild or moderate diarrhea.
