Popis: Abstract Background The majority of dogs with idiopathic epilepsy continue to have seizures despite appropriate treatment. Objectives To assess the use of a commercially available, collar‐mounted accelerometer to detect generalized seizures in dogs. Animals Twenty two client‐owned dogs with idiopathic epilepsy. Methods Six‐month prospective clinical study during which dogs wore a collar‐mounted accelerometer. Seizure documentation was based on owner observations and video recordings. The accelerometer used a predefined algorithm to detect seizures in the first study phase, and an individualized algorithm in the second study phase. Caregivers completed a quality of life (QoL) questionnaire at the initial and final study visit. Results Using the predefined algorithm, the accelerometer detected seizures with a sensitivity of 18.6% (95% CI [13.4%, 23.8%]) and mean false detection rate of 0.096/day. Values did not change significantly with use of an individualized algorithm (sensitivity 22.1%, 95% CI [15.1%, 29.0%]; false detection rate 0.054/day). Mean composite QoL score was significantly improved at study completion (50.42) compared to study initiation (39.53; P = .005), and this change was moderately correlated with a change in weekly exercise (r = 0.46, P = .05). Conclusions and Clinical Importance Generalized seizures in dogs can be detected with a collar‐mounted accelerometer, but the overall sensitivity is low.
