Why did so many dogs fall in the well?

During the 1890s, at Johnson School House, a hand-dug well was in the process of being completed and it was left uncovered. A preaching in a nearby brush arbor resulted in 13 dogs falling into the well. One gets the idea, after reading the 1936 Stephenville Empire-Tribune article, that dogs took advantage of the gathering to meet and greet. After the dogs were pulled out, a new well had to be dug because of the unlucky number.
