ET has learned that one of Oprah Winfrey's two newly-adopted puppies has passed away.
Ivan, a golden cocker spaniel mix that Winfrey adopted earlier this month, passed away late last week from parvovirus. Winfrey adopted Ivan shortly after adopting his sister Sadie earlier this month. In the March 6 episode of "The Oprah Winfrey Show," Ivan was held up by "Oprah" show panelist Alexandra Wentworth.
ET has learned that Sadie also has parvovirus, an infectious disorder that can cause diarrhea and vomiting in dogs. Sadie is currently in stable condition.
"I'm saddened by his passing though we only had him for a weekend," Winfrey tells ET. "I remain hopeful that Sadie will pull through."
