(Reuters) - A pit bull named Big Boi began menacing George and Shellie Zimmerman in the fall of 2009.
The first time the dog ran free and cornered Shellie in their gated community in Sanford, Florida, George called the owner to complain. The second time, Big Boi frightened his mother-in-law's dog. Zimmerman called Seminole County Animal Services and bought pepper spray. The third time he saw the dog on the loose, he called again. An officer came to the house, county records show.
"Don't use pepper spray," he told the Zimmermans, according to a friend. "It'll take two or three seconds to take effect, but a quarter second for the dog to jump you," he said.
"Get a gun."
That November, the Zimmermans completed firearms training at a local lodge and received concealed-weapons gun permits. In early December, another source close to them told Reuters, the couple bought a pair of guns. George picked a Kel-Tec PF-9 9mm handgun, a popular, lightweight weapon.
By June 2011, Zimmerman's attention had shifted from a loose pit bull to a wave of robberies that rattled the community, called the Retreat at Twin Lakes. The homeowners association asked him to launch a neighborhood watch, and Zimmerman would begin to carry the Kel-Tec on his regular, dog-walking patrol - a violation of neighborhood watch guidelines but not a crime.
