This is an original press photo from Universal Studios with the following description:
He was a really worried looking Boxer puppy at the moment when this shot of him was snapped on Tony Curtis' shoulder, be he needn't have been. Present to handsome Tony by a Las Vegas fan when Universal Interational's compnay was there making scenes for "Johnny Dark". The puppy had just acquired a move star master and was really a lucky dog. Tony is in costume as a sports car racer, "Johnny Dark", being a Technicolor thriller with a Canada-to-Mexico race as its big climax. Piper Laurie and Don Taylor star with Curtis.
He obviously had a long time love affair with Boxers
