The unexpected moment occurred while Clinton was telling a story about fact-checking Republicans, whom she accused of twisting the truth about the Great Recession. Clinton explained that it reminded her of an old radio ad she liked in Arkansas where a dog would bark every time a candidate said something that wasn’t true.
“The dog was barking on the radio and so people were barking at each other for days after that,” Clinton said. "I want to figure out how we can do that with Republicans.”
Clinton went on to say that she wished every time Republicans said things like, "'Oh, the Great Recession was caused by too much regulation,'" she had a dog to bark at them.
And that's when the dog impression occurred.
"Arh, arh, arh, arh!" she said in a high-pitched tone. "You know?"
She added: "I think we could cut right through a lot of their claims."
