David Letterman is welcoming another dog into his home -- but that may not be good news.
Amy Sedaris appeared on the "Late Show With David Letterman" on Monday night, and the duo got to talking about pets and how they get along with other animals. After confirming that Letterman was indeed getting a second dog, Sedaris asked what would happen to his current dog, Sully.
Letterman replied that his wife had read that getting another dog will "cause intestinal hemorrhaging and kill the first one.”
Judging by the photo of "Sully," we're pretty sure he'll be able to handle himself just fine.
