The stages of sleep that people go through are also present in dogs.
One of these stages is referred to as REM sleep, which stands for "rapid eye movement" sleep.
Dogs exhibit a higher level of brain activity while they are in the REM stage of sleep.
Because of the heightened brain activity, dogs may experience twitching, movement in their legs, and even vocalization.
When a dog is in the REM stage of sleep, it may appear as though it is running or chasing after something.
There is absolutely no need for alarm regarding this conduct as it is quite typical.
It is essential to refrain from disturbing dogs when they are in the REM stage of their sleep.
