Brachycephaly can predispose dogs to sleep apnea, according to study

Researchers from the University of Helsinki have experimented with a new method for diagnosing sleep apnea in dogs using a sleep apnea mask designed for human diagnostics. The measurements revealed a higher occurrence of sleep apnea in brachycephalic dogs compared to dogs with longer snouts.

Brachycephalic dogs have been found to experience obstructive sleep apnea, similar to that seen in humans, which is characterized by the temporary cessation of airflow due to the narrowing of the upper airways when muscles relax during sleep.
