Chronic enteropathies are common gastrointestinal diseases in domestic dogs characterised by long-term duration, often impairing quality of life both for pets and owners. In this work, we report the encouraging results of a faecal transplantation on a 9-year-old dog suffering from chronic enteropathy for the last 3 years.

Differences between individuals in their gastrointestinal microbiomes can lead to variation in their ability to persist on particular diets. Koalas are dietary specialists, feeding almost exclusively on Eucalyptus foliage but many individuals will not feed on particular Eucalyptus species that are adequate food for other individuals, even when facing starvation. We undertook a faecal inoculation experiment to test whether a koala’s gastrointestinal (GI) microbiome influences their diet.

Frequently just prior to or at weaning (approximate age, 6 to 8 wk), puppies in research settings often develop diarrheal disease, which may be due, in part, to an immature and unstable intestinal microbiota that is permissive to opportunistic pathogens. The overall objective of this study was to assess whether fecal microbiota transfer (FMT) increased the transmission of a stable maternal microbiota to pups and decreased the incidence of postweaning diarrhea.

In canine medicine, FMT administered via enema seems to be beneficial in acute gastrointestinal disorders. Repeat FMT treatments shortened duration to return of formed feces and hospital stay in puppies with parvovirus infections. In addition, a single FMT was superior to metronidazole in the treatment of acute enteritis. The effects of FMT in chronic gastrointestinal disorders are much less well documented, although the existing data consisting of case reports and small case series seem to document that the technique may be beneficial in some instances. However, more data are needed to define which canine patients could be helped by FMT.

In dogs, antimicrobial therapy for Clostridioides (Clostridium) difficile infection (CDI) is based solely on metronidazole, leaving limited treatment options in case of recurrent disease. Fecal microbiota transplantation (FMT) has been successfully used in humans with recurrent CDI, whereas the usefulness of this approach is largely unknown in dogs. In the present study, a dog with a chronic-recurring diarrhea was treated with FMT via colonoscopy.

Environment, diet, and host phylogeny are the main factors that shape the gut microbiota of humans and animals. Gut microbial communities of captive animals are often drastically altered by disease or anthropogenic activities. These changes in the microbial community profoundly influence animal fitness. Fecal microbiota transplantation (FMT) offers enormous potential to mend a disturbed gut microbiota. In addition, differences generally exist between the gut microbiotas of wild and captive animals. FMT can be used to improve the gut bacterial community structure of candidate endangered animals before releasing them into the wild.

Fecal microbiota transplant (FMT), a technique used to restore normal intestinal microbial communities, has been successful in treating humans with Clostridioides difficile colitis. Subsequently, FMT is being used in veterinary patients with suspected intestinal dysbiosis. Unfortunately, little data are available regarding best practices for FMT in horses. The objective of this study was to evaluate the effects of storing manure prepared for equine FMT (MP-FMT) at −20°C for up to 4 weeks and passage through a simulated proximal gastrointestinal (GI) tract on the viability of MP-FMT.


McKinney et al. (2021). PLoS ONE, Vol. 15(3): e0230148.

Fecal microbial transplantation (FMT), a treatment for certain gastrointestinal conditions associated with dysbiosis in people, is also empirically employed in horses with colitis. This study used microbiota high-throughput sequencing to compare the fecal microbial profile of healthy horses to that of geriatric microbial transplant recipients experiencing diarrhea and tested whether FMT restores microbiota diversity.

Recently, fecal microbiota transplantation (FMT) has been tested in veterinary medicine as a treatment option for multiple gastrointestinal (GI) diseases, such as inflammatory bowel disease (IBD). However, there are no reports of changes in the microbial diversity of fecal microbiome after treatment with FMT in canine IBD cases. Moreover, little is known about the long-term efficacy and safety of FMT treatment for dogs. Herein, we present a case of canine intractable IBD treated with repeated, long-term FMT.

In human medicine, fecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridioides difficile infection. It has also been tested as a treatment for multiple gastrointestinal diseases, including inflammatory bowel disease (IBD). However, only a few studies have focused on the changes in the microbiome following FMT for canine IBD. Here, we performed FMT in nine dogs with IBD using the fecal matter of healthy dogs and investigated the subsequent changes in the fecal microbiome and clinical signs.

A 7-year 6-month-old, castrated male Shiba dog presented with a 1-month history of lethargy, anorexia, vomiting, and frequent watery diarrhea. Weight loss, hypoalbuminemia, anemia, and leukocytosis were detected at the first visit. The dog was diagnosed with non-responsive enteropathy (NRE) based on clinical and histopathological examinations. Since the dog did not respond to the immunosuppressive drugs, fecal microbiota transplantation (FMT) was performed during the treatment with chlorambucil. A single endoscopic FMT into the cecum and colon drastically recovered clinical signs and clinicopathological abnormalities and corrected dysbiosis in the dog.


Sugita, K. (2019). BMC Veterinary Research, Vol. 15(11).

Successful clinical outcomes of faecal microbiota transplantation (FMT) for recurrent Clostridium difficile infection have been reported in humans and a marmoset. However, it has been unclear whether oral FMT was effective for the treatment of C. difficile-associated diarrhoea in dogs.
