4. Boredom: Dogs, especially those left alone for long periods, may resort to engaging in unusual behaviors out of boredom. Chasing and eating worms can provide a form of entertainment for them.

5. Curiosity: Dogs are naturally curious creatures, and they explore the world through their senses, including taste. Eating dead worms could be a way for them to satisfy their curiosity about new and interesting things they find in their environment.

6. Worms as Prey: Dogs have an innate prey drive, and the movement of worms might trigger their hunting instincts. Eating dead worms can be seen as a way for dogs to practice their hunting skills.
