The Lodi City council is considering new rules for owners of potentially dangerous dogs.

If adopted, the city's municipal code will require that any dog or domestic animal must be under the owners' control when not in an enclosed area.

City Manager Steve Schwanbauer said if a dog bites a human or other animal twice, it is considered vicious or potentially dangerous. 

City council members pointed out many times aggressive behavior is a result of poor treatment by the owner, or just plain carelessness.

Also being considered are mandatory cat rabies vaccinations.
