The Newton City Council will be voting on a ordinance that requires owners of vicious dogs to have insurance of at least $50,000 and will review the definition of a vicious dog at tonight’s 6 p.m. meeting.

If adopted, the following changes would be made to the vicious dog ordinance:

• A vicious dog would be defined as, “a dog which has killed a domestic animal or pet or inflicted injury upon a domestic animal pet such that the domestic animal or pet later dies or is euthanized due to the attack may be declared a vicious dog.”
