Some North Little Rock residents are seeking a ban on pit bulls and the city council will be holding public hearings on the proposal. North Little Rock updated its vicious dog ordinance last year to prohibit wolf hybrids, but didn`t ban a specific breed. Pit bulls actually are not a breed, but rather a group of dogs with similar traits and characteristics, according to the Pit Bull Rescue Central Web site. The proposal would allow pit bull owners who currently have a city dog license or who get one before the ordinance goes into effect, to keep their dogs. But the owners must register the dog by allowing city Animal Services to tattoo it for identification purposes. Unlicensed pit bulls or those brought into the city after the law takes effect would be illegal and violators could be criminally prosecuted.
