I had a great dog named Mushroom for 17 years. (RIP, Mushy!) She was a schnauzer poodle mix.
Some years ago, she woke up and ran straight outside and began methodically digging around the back yard, running from one spot to the next-- not a normal thing for Mushroom. It looked to us like she was digging for a bone. But she had not buried one.
We theorized that maybe she dreamed she had buried some tasty bones in the backyard and went to retrieve them upon awakening.
