Dogs dream. Dogs and humans have similar sleep patterns and brain activities. Sleep is divided into rapid eye movement sleep and non-rapid eye movement sleep. In the rapid eye movement sleep state, there is sufficient time to dream. If you see your dog's eyes moving, sobbing slightly, or humming while sleeping, it means it is dreaming. Do not disturb it to avoid being frightened.

Dog sleeping posture:

1. All four legs are in the air. Sleeping on your back is a defenseless and very relaxing state for your dog.

2. Talk while sleeping. Although its body is sleeping, its head is awake and likely dreaming.

3. Farting while sleeping. When a dog sleeps, the whole body will relax, the muscles around the buttocks will relax, and farting will occur.

4. Stick out your tongue. This is also a symbol of deep sleep. If the mouth is relaxed, the tongue will naturally stick out.
