There are usually several reasons why dogs like to sleep next to their owners:

Security and dependence Feeling: Dogs are social animals and they develop close relationships with their owners. Sleeping next to their owner makes them feel safe and protected, which is a sign of dependence.

Warmth and Comfort: The owner’s body radiates warmth and is a comfortable place for the dog. They may choose to stay close to their owners to enjoy a warm and comfortable sleeping environment.

Emotional Bond: There is a strong emotional bond between a dog and its owner. Sleeping next to their owner can strengthen the bond between them and make the dog feel closer to their owner.
