Dog Behavior Research

This article explores whether dogs experience jealousy or a form of fairness by examining inequity aversion in canine behavior. It reviews key studies showing that dogs react negatively to unequal reward distribution, particularly in social contexts, and concludes that these responses reflect violated expectations rather than a true moral understanding of fairness.

This article examines separation anxiety in dogs as a neurobiological panic disorder rather than a behavioral problem. It explores the roles of the amygdala, HPA axis, and neurotransmitter systems in driving fear responses, and highlights why affected behavior is involuntary. Clinical implications for treatment and management are discussed.

This article examines how chronic stress influences telomere dynamics and accelerates cellular aging in dogs. Through oxidative stress and inflammation, persistent anxiety contributes to telomere shortening and genomic instability. The implications for canine health, welfare, and lifespan are discussed.

This article examines the relationship between chronic pain, particularly osteoarthritis, and aggressive behavior in dogs. Persistent nociceptive input alters neurochemical signaling, stress responses, and emotional regulation through shared neural pathways. The clinical relevance of pain assessment in behavioral cases is critically discussed.

This article examines the gut–brain axis as a link between the gastrointestinal microbiome and central nervous system function. In dogs, microbial activity influences stress responses and behavior through neural and immune pathways. Key mechanisms and their relevance for veterinary behavioral medicine are outlined.

This review examines separation anxiety in dogs from a neurobiological perspective. It explains how separation from a caregiver can activate panic-related stress circuits involving the amygdala and the HPA axis.

This review summarizes research on emotional contagion between humans and dogs. Evidence suggests that human stress can influence canine stress responses and affect welfare and behavior.

This article examines canine reactivity from a neurological perspective, explaining how intense emotional arousal can shift brain activity from the prefrontal cortex to the amygdala and trigger reactive behavior.

This article examines how aversive training methods affect the canine brain, including stress responses in the amygdala, hippocampus, and HPA axis. It discusses the behavioral and welfare consequences of punishment-based training, including anxiety, avoidance, and learned helplessness.

This article explores whether dogs truly understand cause and effect or primarily rely on associative learning. Drawing on experimental research, it highlights that while dogs do not show robust spontaneous causal reasoning, they can learn to adjust their behavior based on experienced causal regularities. The findings have important implications for training and behavior therapy.

This article explores whether dogs demonstrate metacognitive-like abilities by reviewing research on the knowledge-seeking paradigm and uncertainty monitoring. It evaluates empirical evidence, methodological challenges, and neural considerations, and discusses the implications for learning and behavior therapy.

This article explores how chronic stress alters the canine stress system, including the HPA axis and cortisol regulation. It outlines the long-term behavioral consequences such as anxiety and aggression, and emphasizes that effective training focuses on stress regulation rather than suppression.

This article explains the genetics of the Merle gene in dogs, its inheritance, and the health risks linked to double merle breeding. It highlights pigmentation mechanisms, sensory impairments, and the importance of responsible breeding and genetic testing to protect canine welfare.

This article reviews current scientific research on canine cognition, highlighting problem-solving skills, memory, social intelligence, and learning abilities in domestic dogs.

This article examines the role of oxytocin in dogs and humans, explaining how hormonal processes contribute to emotional bonding, trust, and social attachment between dogs and their caregivers.

This article explores the neurological foundations of dog behavior, focusing on brain structures, neural processes, and learning mechanisms that influence training outcomes and behavioral responses.

This article outlines how epigenetic mechanisms in dogs allow environmental factors such as stress, nutrition, and social interaction to influence gene expression without altering the underlying DNA sequence.
