“…The only potential risk factors previously identified in dogs for developing CCDS as assessed by CADES were aging and eating an uncontrolled diet (table scraps, mixture of diets, or low‐quality commercial food), whereas other factors such as weight, sex, reproductive status, and housing type were not significantly associated with cognitive impairment 42 . Another study, which used the canine cognitive dysfunction rating scale to assess for cognitive impairment in dogs >7 years old, did not find any significant differences in normal dogs and dogs with CCDS with factors such as age, breed, sex, body weight, reproductive status, nutrition, and medications 43 . We believe that presbycusis could be a newly identified risk factor in dogs for development of CCDS based on CADES scoring and reduction in executive function test performance.…”

Background: Elderly people with presbycusis are at higher risk for dementia and depression than the general population. There is no information regarding consequences of presbycusis in dogs.Objective: Evaluate the relationship between cognitive function, quality of life, and hearing loss in aging companion dogs.Animals: Thirty-nine elderly companion dogs.Methods: Prospective study. Hearing was evaluated using brainstem auditory evoked response (BAER) testing. Dogs were grouped by hearing ability. Owners completed the canine dementia scale (CADES) and canine owner-reported quality of life (CORQ) questionnaire. Cognitive testing was performed, and cognitive testing outcomes, CADES and CORQ scores and age were compared between hearing groups.Results: Nineteen dogs could hear at 50 dB, 12 at 70 dB, and 8 at 90 dB with mean ages (months) of 141 ± 14, 160 ± 16, and 172 ± 15 for each group respectively (P = .0002). Vitality and companionship CORQ scores were significantly lower as hearing deteriorated (6.6-5.4, 50-90 dB group, P = .03 and 6.9-6.2, 50-90 dB group, P = .02, respectively). Cognitive classification by CADES was abnormal in all 90 dB group dogs and normal in 3/12 70 dB group and 11/19 50 dB group dogs (P = .0004). Performance on inhibitory control, detour and sustained gaze tasks decreased significantly with hearing loss (P = .001, P = .008, P = .002, respectively).In multivariate analysis, higher CADES score was associated with worse hearing (P = .01).
