Then Came Bob Clifford the Big Red Dog : Season 1 Episode 58

Vaz babysits for Bob - a cute, but not very well-behaved little dog that Dr. Dihn recently acquired from the dog pound. This little mischief-maker is very good at getting into trouble – and causing Clifford to get the blame! Several people think Clifford has suddenly developed some very bad habits – but Emily Elizabeth never doubts her big dog for a minute. The truth about Bob finally comes out and Clifford receives apologies from all his doubters.
