The duties of a bather involve pet grooming. Their responsibilities are to wash, brush, and fluff a dog or other pet. A bather may prepare the animal for various grooming services or wash them as a stand-alone service. Other duties may include cleaning the grooming salon, interacting with customers, setting appointments, and caring for the dog or other pet until another staff member is ready to work with them. The qualifications that you need to become a bather vary, but often include a high school diploma or GED certificate and on-the-job training.
