More awesome articles from Zak George and Bree. Studies listed at the end, as usual.
Dogs aren’t “misbehaving”. Their brains might be more like ours than you think… and the evidence continues to support a new approach to training.
Could your dog’s hyperactive behavior actually mirror ADHD in humans?
A comprehensive Finnish study surveyed over 11,000 pet dogs, and discovered striking parallels between canine behaviors and human ADHD symptoms, specifically hyperactivity, impulsivity, and inattention.
Nearly 1 in 5 dogs displayed pronounced inattentive behaviors, and about 15% exhibited significant hyperactivity and impulsivity, far beyond typical puppy energy.
Like humans, these traits were more common in younger dogs and males, with social isolation amplifying the symptoms.
Breed differences also emerged: Dogs historically bred for active roles (like terriers and working breeds like German Shepherds) showed higher tendencies toward hyperactivity and impulsivity, while companion breeds showed lower levels. Interestingly, breeds not specifically selected for intense tasks often scored higher in inattention, which is evidence that selective breeding can shape canine cognition significantly.
Still, it’s really important that we don’t oversimplify this. Every dog is an individual, and breed alone never tells the whole story.
Beyond genetics, the environment plays a substantial role. Dogs left alone frequently exhibited increased hyperactivity and attention issues, highlighting the importance of enrichment and social engagement.
Moreover, this research unveiled critical links between “ADHD-like” behaviors and anxiety-related issues in dogs, including obsessive-compulsive tendencies and aggression. Dogs displaying extreme impulsivity or inattention often showed coexisting anxiety or fear-based behaviors, so there could be a potential underlying neurobiological connection. This mirrors findings in human ADHD, where anxiety and compulsive behaviors often coexist.
Why is this significant? It underscores the critical need for compassionate, positive, neuroaffirming training methods rather than outdated, punitive approaches. Aversive techniques, such as leash corrections or shock collars, have been shown to heighten stress and exacerbate behavioral problems, making ADHD-like symptoms worse.
Conversely, structured, positive, enrichment-focused approaches help these dogs channel their energy constructively, significantly improving their focus and emotional stability.
It’s important to clarify that “ADHD-like” doesn’t mean your dog has human ADHD. It’s an analogy that helps us understand their behavior better without anthropomorphizing. Recognizing these behaviors allows us to better support dogs struggling with focus and impulsivity, and improve their quality of life through targeted, humane training.
This research invites us to shift our mindset: Dogs often labeled as “stubborn” or “unmanageable” might actually be neurologically predisposed to hyperactivity or distraction.
Rather than applying harsher discipline, we should lean into empathy, structure, and enriching activities. This evidence supports what many trainers and behaviorists already advocate: understanding and positive engagement, not punishment, bring out the best in our dogs.
