Ok this will get a big Awww - he is an Actor - but 4 legged one - screen 캡, 모자 from the opening credits of his TV show "Sue Thomas FBeye".
For those who are not familiar with the show - Jesse Renfro plays Levi the dog who works with his owner at the FBI. His owner is deaf and he is a hearing assistant. The scene is him letting her know that someone is at the door when she is in the tub - he jumps in.
