Published in Topics in Companion Animal Medicine, this review by K. Overall emphasizes that dogs serve as valuable models for studying anxiety-related disorders and age-associated cognitive decline in humans. At the same time, canine learning and problem-solving abilities are important subjects in their own right, revealing the complexity of dog cognition.
The author discusses how stress and distress can alter learning at the molecular level, disrupting neurotransmitter balance, impairing memory formation, and lowering the efficiency of problem-solving. Likewise, factors that influence olfaction—a primary sensory modality for dogs—can significantly impact their ability to learn, detect odors, and navigate their environment.
Breed differences also contribute to variability in cognitive performance and learning styles. Genetic background may influence attention, working memory, sensory processing, and responsiveness to training.
A particularly important theme in the review is the role of nutrition. Diet can affect brain energy availability, oxidative stress, and neurochemical function, thereby modulating cognitive performance and potentially influencing the progression of brain aging.
Overall, the review underscores how canine cognition results from the dynamic interplay of biological, emotional, and environmental factors. Understanding these influences can improve training practices, enhance welfare, and inform approaches to mitigating cognitive decline in aging dogs.
