A Hound For Trouble is a 1951 Warner Bros. Merrie Melodies cartoon short directed by Chuck Jones.
The restaurant's owner eventually seems to accept Charlie as a partner, but he actually uses the dog's newfound trust to fool him.
As he returns, Charlie sees that the owner has gone out for 15 minutes ("15 minootsa") and decides to run the restaurant himself.
The owner finally appears to relent and starts walking Charlie home.
The owner suddenly yells that the Tower of Pisa (which Charlie, being unfamiliar with the monument, does not realize is perpetually leaning) is "about to fall on that little house!"
