What constitutes a dangerous dog?

There has been some discussion in Lester Prairie about what constitutes a dangerous dog. Last summer, a rottweiler named Lexy was classified as potentially dangerous after residents reported being frightened by Lexy as they walked down a public street. Police talked to Lexy’s owner about steps he could take to avoid having her classified as a dangerous dog. The owner did not heed this advice, and police recieved additional reports about people being frightened by Lexy. As a result, she was classified as dangerous. The owner appealed, and the city council upheld the decision.

Some people say the city over-reacted, and the dog should not be classified as dangerous because she has not physically attacked anyone. Others say the city did what it had to do to abide by the law, and to protect city residents.
