Dr. Andy Roark welcomes Dr. Lily Chen, DVM, owner of Integrative Pet Wellness Center in Los Angeles, to talk fecal transfers and microbiome therapy for chronic diarrhea cases that keep cycling back to antibiotics. Using a 10-year-old German Shepherd with recurrent diarrhea as the example, Lily explains why dysbiosis can be a root cause, when she starts with microbiome testing (including the Texas A&M Dysbiosis Index), and how she uses commercially prepared donor material to perform quick, non-anesthesia, rectal “retention enema” fecal transplants in repeated sessions. She shares expected timelines, her typical eight-session protocol with retesting, clinical and behavioral improvements clients often notice, why oral transfer systems have been less durable in her experience, and how she reassesses when results are limited. She also shares where to find her on Instagram.
