Physical exercise is essential for dog welfare but insufficient alone — mental enrichment, social interaction, and species-appropriate activities are equally important for canine wellbeing.
Dog enrichment science has moved far beyond "a tired dog is a good dog" to recognize that mental engagement is as important as physical exercise for canine welfare. Dogs evolved as working animals with complex behavioral repertoires — bred over thousands of years for tasks requiring intelligence, cooperation, problem-solving, and persistence. A modern companion dog spending most of its day in a house with nothing cognitively engaging to do is experiencing a form of deprivation that physical walks alone cannot address. Scent work, puzzle feeding, training sessions, and appropriate social interaction all provide forms of enrichment that meet dogs' behavioral needs in ways that physical exercise cannot replicate.
