Human-like associations between gut microbiome composition and inattention, hyperactivity, and impulsivity in dogs.
Article in BMC biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEvidence suggests a link between attention-deficit/hyperactivity disorder (ADHD) and the gut microbiome in humans. Dogs are a valuable model for ADHD research, as their gut microbiome more closely resembles the human gut microbiome in composition and functional overlap compared to rodent models. This study investigated potential associations between dogs' ADHD-related traits and gut microbiome composition/diversity. We assessed inattention, Hyperactivity, impulsivity, and related functional impairments of 164 family dogs using the validated Dog ADHD and Functional Rating Scale, and analysed bacterial 16S rRNA gene sequences from their faecal samples to assess the gut microbiome composition.
resultsHigher relative abundance of members of the family Prevotellaceae and genus Prevotella was associated with lower inattention and inattention-related functional impairment scores by both decision tree and Generalized Linear Model analyses. Hyperactivity, impulsivity, and related functional impairments were found to be moderated by age, suggesting that these traits are predominantly age-related and only secondarily influenced by microbiome composition. ADHD total score was negatively associated with Erysipelotrichaceae and positively associated with Alloprevotella. Dogs with higher functional impairment scores had lower alpha-diversity in their gut microbiome, probably indicating reduced microbial health.
conclusionsThis is the first study that found negative associations between inattention and the relative abundance of Prevotellaceae in dogs, which parallels findings in human studies. Our current correlational results in family dogs represent only the first step in gaining more insight into the interplay of gut microbiome and neurodevelopmental processes in non-human animals.
