This law provides that the owner, harborer, or keeper of any animal (whether or not a dog) is liable for injuries to people, whether or not caused by a bite. Although the Animal Control Act law uses the word "owner," the term is defined as "any person having a right of property in an animal, or who keeps or harbors an animal, or who has it in his care, or acts as its custodian, or who knowingly permits a dog to remain on any premises occupied by him or her." (510 ILCS 5/2.16)
