flag Teens with dogs show better mental health due to beneficial microbes from dog contact, per a new study.

flag A study published in iScience links dog ownership in adolescence to improved mental wellbeing, suggesting that close contact with dogs alters the human gut and oral microbiome. flag Researchers found teens with dogs had higher levels of certain bacteria, including Streptococcus, associated with reduced social withdrawal and depression. flag Mouse experiments showed that microbes from dog owners led to increased prosocial behaviors. flag The findings suggest that microbial exchange through licking or physical interaction may influence mental health via the gut-brain axis, though further research is needed to confirm these effects across diverse populations.
