Wonder Dog (1950)

Pluto is smitten with Dinah, who won't give him the time of day; instead, she moons over Prince, the Wonder Dog (as seen on a circus poster). Pluto envisions himself performing Prince's tricks. A nearby trash-filled yard has what Pluto needs to fulfill his fantasy, and discover just how hard some of the tricks are. It also has Butch, who is amused by all this, but soon goes after Pluto. In escaping Butch, Pluto manages to successfully do most of Prince's stunts, and his lover sees him. —Jon Reeves
