<p style="text-align:justify"><strong>Flat-faced dog breeds are popular all over the world. In the USA and in Hungary, the French Bulldog is currently the most common breed. However, their popularity comes at a high cost in terms of health: shortened skulls are associated with deteriorative brain morphology changes, breathing difficulties and sleep problems. According to recent <a href="https://doi.org/10.1007/s00429-023-02706-y" target="_blank">findings</a> by Hungarian researchers, flat-faced dogs sleep more because their breed-specific sleep apnea increases daytime sleepiness, their REM sleep phase is longer than non-REM sleep, and their sleep EEG patterns show signs of white matter loss.</strong></p>
