Sandra Wesenberg illustrates the potentials, as well as the limitations, of animal-assisted interventions in dementia care through an overview of various international studies and her own empirical research. Additionally, she comprehensively explains the mechanisms of action underlying beneficial human-animal interactions and how the specific needs of people with dementia can be met in interactions with animals.
