The global prevalence of obesity is higher in older pets, reaching approximately 50% of the total pet population across all age groups. New research from the American Society for Microbiology shows that probiotics can reshape the gut microbiome and energy metabolism in overweight and obese dogs. Researchers have identified 2 strains of probiotics that can be used to reduce canine pet weight: Enterococcus faecium IDCC 2102 and Bifidobacterium lactis IDCC 4301. The strains, says researchers, has demonstrated remarkable success in reducing the body fat percentage in dogs. The study says that there needs to be further research on probiotics especially tailored for pets, and there is a vast array of probiotic types that hold potential applications.
