Published in Animals, this review by Ángela González-Martínez and colleagues presents the latest understanding of ADHD-like syndromes in dogs. The authors propose that certain canine behavioral patterns—marked by impulsivity, hyperactivity, and attention deficits—mirror human ADHD, positioning dogs as a valuable model for exploring this neurobehavioral condition.
The review explains that ADHD-like behavior in dogs arises from dysregulation of neurotransmitters, notably serotonin and dopamine, which are also implicated in human ADHD. The expression of these behaviors reflects a gene–environment interaction, influenced by both hereditary predispositions and early-life experiences such as poor socialization, inconsistent training, or high-stress environments.
Dogs exhibiting ADHD-like symptoms often display significant comorbidities, including compulsive behaviors, aggression, inappropriate elimination, fearfulness, epilepsy, foreign body ingestion, and pruritus (itching). These secondary conditions further complicate diagnosis and management. While there is currently no formal veterinary diagnostic framework for ADHD-like disorders, validated behavioral questionnaires can assist in assessing impulsivity and attentional control, though they cannot serve as definitive diagnostic tools.
Treatment approaches emphasize a combination of behavioral modification, environmental enrichment, relaxation protocols, and, in some cases, pharmacological interventions such as fluoxetine. These strategies aim to stabilize neurochemical imbalances, reduce stress, and enhance overall quality of life for both dogs and caregivers. The authors also call for greater interdisciplinary collaboration between veterinary behaviorists and neurologists to refine diagnostic standards and therapeutic approaches.
Ultimately, González-Martínez et al. advocate for a nuanced understanding of canine ADHD-like behavior as a multifaceted welfare concern, urging veterinarians and owners alike to consider both biological and environmental contributors to hyperactivity and inattention in dogs.
