Study reveals changes in intestinal microbiota composition with age in dogs, suggesting implications for health management.

This study aims to examine how the intestinal microbiota of dogs changes as they age.
Collected fresh fecal samples from dogs across five age groups: pre-weanling, weanling, young, aged, and senile.
Analyzed microbiota compositions using culture-based methods and 16S rRNA gene sequencing.
Lactobacilli showed a decrease in both number and prevalence as dogs aged.
Bifidobacteria were not predominant in the intestinal microbiota of dogs.
The species composition of Lactobacillus varied with age.

Masuoka et al. (2016) studied this question.
