    The digestive tract hosts various types and numbers of microorganisms. These microorganisms 'micro-organs' play multiple crucial roles in physiological, immunological and metabolic processes in the body. The 'micro-organ' manipulation and transplantation has lately gained an increasing interest in human medicine with promising clinical outcomes, whereas much less is known in veterinary practice.The goals of this pilot study were to evaluate safety and impact of Fecal Microbiota Transplantation (FMT) on dogs suffering with non-infectious digestive disorders.Animals: Seven client-owned adult dogs with idiopathic persistent diarrhea (>3 weeks) and very poor skin-coat conditions were receiving the intervention (FMT) and evaluated in a private veterinary clinic.Transplants have been taken from healthy donors and were administered rectally to recipients. Objective clinical examinations with analyses of blood and feces samples at day 0 (pre-FMT), day 14 -28 (post-FMT) were performed. Besides the conventional blood hematology and biochemistry analyses, 16S rRNA sequencing analysis were used in fecal samples.No FMT related complications have occurred. Five of seven (71%) patients have improved feces parameters associated with better overall clinical outcome, whereas four of the five (80%) recovered recipients showed molecular correlation with the donor gut microbiota after rectal FMT. There were in-significant changes in conventionally analyzed blood samples.The serum cobalamin levels showed tendency to increase in recovered recipients.Conclusions: FMT was easy to apply with certain health benefits in this study. Our findings reveal the important role of a 're-gained' gut microbiome balance in the overall health of dogs.Further research is needed to identify the dynamics and interplay between the different bacteria phyla that may have impact on stimuli of host immunologic and metabolic responses.
