NEW MILFORD — Police said a local man shot his neighbor’s dog with a BB gun after the animal went into his property and growled at him. Christopher Mumford, 63, was arrested on a warrant Tuesday and charged with animal cruelty and criminal mischief. The incident took place on April 6, but the arrest warrant was just recently approved by state Superior Court in Bantam. The dog had surgery and has since recovered, police said. Mumford was released on a promise to appear in court May 31.
