A pet care assistant provides in-home care for domestic animals. Your responsibilities depend on the kind and breed of the pets in question, but may include walking dogs, administering prescribed medication, cleaning litter boxes, and providing exercise opportunities. Duties often involve feeding and monitoring their habits, and occasionally basic obedience training. Pet care assistants may use a variety of alternate job titles, such as pet sitters, doggie daycare providers, and boarding facility workers. Some veterinary clinics have a caretaker on staff to manage animals that are injured or sick.
