The phases dogs go through when sleeping are very similar to the sleep cycles humans experience, and that includes the rapid eye movement cycle when dreaming occurs, also known as REM Dogs experience two phases of sleep in a complete cycle: the slow-wave phase and the REM phase.
The slow-wave cycle begins as soon as your dog falls asleep and lasts for 10 to 20 minutes, then he shifts into the REM cycle.
The length of the complete cycle can last 30 to 45 minutes and depends on the dog s size and how old he is.
L arger dogs typically dream for approximately 5 minutes every 45 minutes while smaller dogs only dream for a minute or less every 10 minutes.
