Friend was a quail hunter and had a bird dog. It would work for about 45 minutes then would just take off running. He would get called a couple of days later and go pick up his dog from wherever it stopped, sometimes 20 miles from where she took off. He found out later the dog was hypoglycemic and when her blood sugar dropped she would lose her mind and just run. Stopped it by feeding her treats while hunting with her.
