Free-ranging dog
A domestic dog that moves freely outside direct human control, whether owned, unowned, or loosely associated with people.
Dog social behavior: The ways dogs communicate, form relationships, and coordinate behavior with other dogs and people. Social bonds shape how free-ranging dogs form groups, compete, and interact with people.
Animal birth control: Methods used to prevent or reduce reproduction in animals. Sterilization programs aim to reduce unwanted litters among roaming dogs.
Rabies: A viral disease that attacks the nervous system and is usually fatal after symptoms begin. Dogs are the main source of human rabies infections in many parts of the world.
Stray dog: A dog that is lost, abandoned, or otherwise living without reliable human care. Stray dogs are one subset of free-ranging dogs, not a synonym for the whole category.
Canine territorial behavior: The use of space, scent, and behavior to defend or maintain access to resources. Territorial behavior influences where roaming dogs forage, rest, and encounter other groups.
Catch-neuter-vaccinate-return: A program that captures free-roaming dogs, sterilizes and vaccinates them, then returns them to their location. This method targets reproduction and rabies while leaving dogs in familiar territories.
Zoonosis: An infectious disease that can pass naturally between animals and humans. Roaming dogs can carry pathogens that reach people through bites, contact, or contaminated environments.
Feral dog: A domestic dog living independently of people and showing little or no ongoing human association. Feral dogs have less human association than the broader free-ranging category allows.
Scavenging: Feeding on dead animals or discarded food rather than killing all food directly. Human refuse and carcasses can sustain dogs that forage beyond household care.
Dog shelter: A facility that houses dogs temporarily or permanently, often for care, adoption, or protection. Shelters receive some roaming dogs, but capacity and long-term outcomes constrain their use.
