Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
The canine gut microbiome is a dynamic ecosystem that develops rapidly after birth, matures during weaning and growth, becomes comparatively stable in adulthood, and changes heterogeneously with aging. Gut microorganisms contribute to fermentation of nondigestible substrates, production of short-chain fatty acids and indole derivatives, bile acid transformation, mucosal immune regulation, epithelial barrier maintenance, and colonization resistance. Early life is highly plastic and sensitive to maternal, dietary, infectious, and antimicrobial exposures, whereas adult health depends more on functional redundancy and ecological resilience than on a fixed taxonomic profile. In senior dogs, reported age-associated changes are inconsistent because they are strongly influenced by breed size, diet, obesity, activity, multimorbidity, oral health, and medication. This review focuses on microbiome development across life stages, the relationship between microbial function and gastrointestinal health, and practical approaches to preserve or improve microbial resilience. Evidence supports gradual dietary transitions, nutritionally complete diets, suitable fermentable fibers, maintenance of healthy body condition, parasite control, and prudent antimicrobial use. Probiotics, prebiotics, synbiotics, and postbiotics may be beneficial in selected settings, but effects are strain-, substrate-, dose-, diet-, and disease-specific. Longitudinal multi-omics studies with clinically relevant outcomes are needed before age-specific biomarkers or personalized microbiome interventions can be applied reliably in veterinary practice.
