EEG Recordings of Dogs in Sleep: Control and Trazodone Conditions

Data Availability Statement The dataset includes polysomnographic recordings (EEG, EOG, EMG, and ECG) obtained from twelve young, healthy domestic dogs. Each subject underwent three sessions on separate days: acclimatization, recording with trazodone (5 mg/kg, oral), and recording without trazodone. Demographic information (breed, sex, weight, and age) for all animals is provided. Recordings were collected using gold-coated electrodes and Cadwell Easy II software at a sampling rate of 400 Hz, with electrode impedance maintained below 20 kΩ. All animals were client-owned and enrolled as age controls in an ongoing longitudinal study on neuro-aging at North Carolina State University. Procedures were approved by the NCSU Institutional Animal Care and Use Committee (protocol number 21-303). Written informed consent was obtained from all owners prior to participation.
