, who has had a long and emotional week, decided to cut it short Thursday and canceled her taping for Friday's program.
"Ellen is taking a long weekend and will be back with a new show on Tuesday," reads a message posted at 1:52 p.m. Thursday on her talk show's Web site
DeGeneres, 49, broke down in tears
on Tuesday's program, revealing that a dog she had adopted, and then given to her hairdresser's family, had been taken back by the rescue agency he came from – upsetting her friend and her daughters.
On Wednesday, the former Oscars host continued her public appeal
for the agency to return the dog, Iggy, to the family, while also learning that Iggy had since been given away to a different family. The same day, it emerged that the Mutts & Moms organization had been receiving death threats – and that one of the partners there had filed a police report alleging harassment.
DeGeneres said on Thursday's show that she would stop discussing Iggy
publicly, but that she was still holding out hope for the dog's return.
