A pet nanny helps a pet owner care for their animals when they are away, at work, or otherwise indisposed. Your duties vary depending on the needs of each client; you may handle feeding, walking, and healthcare for pets on a daily basis or care for them temporarily while their owners are traveling. Regardless of if you work for an agency or as a freelancer, you go to clients' homes to care for pets. Some pet nannies, who are also known as pet sitters or pet caregivers, work at boarding facilities. In such positions, your responsibilities include caring for dogs, cats, or other animals that stay at the facility while their owners are away.
