In a comprehensive review published in Animals, Ángela González-Martínez and colleagues synthesized current knowledge on ADHD-like syndromes in dogs, a condition that parallels human Attention-Deficit/Hyperactivity Disorder in both symptoms and neurobiology. The authors propose that dogs can serve as a valuable model for studying ADHD, offering insights into shared behavioral and neurochemical mechanisms across species.
Dogs exhibiting ADHD-like traits often display impulsivity, hyperactivity, attention deficits, and sometimes aggression, leading to challenges in household management and reduced quality of life for both dogs and their caregivers. These behaviors are linked to dysregulation of neurotransmitters, particularly serotonin and dopamine—key chemicals involved in mood regulation, impulse control, and attention.
The review emphasizes that the condition likely arises from a gene–environment interaction. Genetic predispositions may combine with environmental stressors, inconsistent training, or insufficient enrichment to exacerbate symptoms. Furthermore, dogs with ADHD-like tendencies frequently show comorbidities such as compulsive behaviors, aggression, inappropriate elimination, fearfulness, epilepsy, foreign body ingestion, and pruritus (itching), reflecting complex behavioral and physiological overlap.
Despite its growing recognition, there remains no formal veterinary diagnostic standard for ADHD-like behavior in dogs. The authors suggest that validated behavioral questionnaires can assist clinicians and owners in identifying patterns of hyperactivity and impulsivity but should not be used as a sole diagnostic tool. Instead, an integrative approach combining behavioral observation, history-taking, and physiological assessment is recommended.
Treatment strategies are multifaceted. Behavioral modification and environmental enrichment form the foundation of management, while pharmacological aids such as fluoxetine may help regulate mood and impulse control. Relaxation protocols and consistent routines further support dogs’ emotional regulation and overall well-being. The authors advocate for more research into neurochemical markers and intervention efficacy to advance both veterinary and comparative psychology.
Ultimately, González-Martínez et al. highlight that recognizing and addressing ADHD-like symptoms in dogs enhances not only animal welfare but also strengthens the human–dog bond by promoting understanding, patience, and evidence-based care.
