10. Twitching in their sleep
Dogs can sleep peacefully or deeply and very quickly enter the REM phase (rapid eye movement), where they begin to dream and spasm. That explains why, when they’re asleep, their face shakes uncontrollably, they kick like karatekas, or they bark without even realizing it. It is not recommended to wake them up at that moment, because they can feel out of place and be in a bad mood. Put yourself in their shoes, this also happens to humans all the time…
