Dr. Lisa Walling greets her 13-year-old hospice patient, Rugby, a Newfoundland, in the dog's home in Bedford, N.Y., on Tuesday, May 7, 2024. As an end-of-life care veterinarian, Walling considers both pet and owner to be her patients. She’s there to make sure animals are as comfortable as possible in their final days, and help humans through the difficult decision of knowing when it’s time to say good-bye. At a later visit, after Rugby had deteriorated further, she euthanized her surrounded by her family. (AP Photo/Mary Conlon)
