Georgia has tightened a dog-fighting law that the Washington-based Humane Society of the United States (HSUS) had blasted as one of the weakest in the nation in 2006. The new law, signed by Gov. Sonny Perdue in May, makes it a felony to own, possess, train, transport or sell any dog for the intention of fighting. The new Georgia law sets a penalty of one to five years in prison or a minimum fine of $5,000 for first offenders, making it one of the strongest in the nation.
