Bridging the Gap Between Scientific Knowledge and Owner Perception of Canine Cognitive Dysfunction Syndrome

Abstract

Canine Cognitive Dysfunction Syndrome (CCDS) is a progressive neurodegenerative disorder associated with aging, sharing clinical and pathological similarities with Alzheimer’s disease in humans. Despite its increasing prevalence, CCDS remains significantly underdiagnosed, largely due to limited awareness among dog owners and challenges in early detection. This study aimed to assess the prevalence of CCDS and evaluate owner awareness in the Alentejo region of Portugal, as well as to identify associated risk factors. A cross-sectional observational study was conducted using structured questionnaires administered to owners of dogs aged eight years or older (n = 86). Results revealed that only 9.3% of dogs had a prior diagnosis, whereas 58% exhibited clinical signs consistent with cognitive impairment, indicating substantial underdiagnosis, in agreement with previous findings (Salvin et al., 2010). Additionally, a significant proportion of owners lacked awareness of CCDS. These findings highlight a critical gap between scientific knowledge and owner perception, emphasizing the need for educational strategies and early screening protocols.
