ABSTRACT
Advancements in veterinary medicine have resulted in increased life spans for dogs, necessitating a better understanding of quality of life for older dogs. This study aimed to evaluate quality of life (QoL) progression and its potential association with mortality in senior and geriatric dogs. The Canine Owner-Reported Quality of Life Questionnaire (CORQ), consisting of 17 questions across four domains (vitality, companionship, pain, and mobility) was employed. Higher scores indicated better quality of life, with 7 as the highest potential score for each question. In a cross-sectional analysis including 92 dogs, we found an inverse correlation between overall CORQ (and all domain scores) and fractional lifespan. The domain of vitality demonstrated the lowest scores, while companionship exhibited the highest. A longitudinal analysis, including 34 dogs, revealed that when dogs reach the geriatric stage (100% of their calculated lifespan), their expected overall CORQ is 5.95 out of 7, and dogs are expected to have a monthly decline of 0.05 units in the score. Cox proportional hazard analysis demonstrated a significant association between overall CORQ scores and mortality, with dogs scoring below 5.35 being at a higher risk of mortality. This study underscores the association between aging, declining quality of life, and increased mortality risk in aging dogs.
