The Major boasts to the Adventurer's Club that he finally has a secret weapon to catch the elusive Snagglepuss. The weapon is Snuffles, a canine who will run any risk, brave any terrors, for a dog biscuit. But the Major's parsimony is his undoing. He gives Snuffles only half a dog biscuit. The wily Snagglepuss quickly allies himself with Snuffles, and the Major learns too late he should have given Snuffles more.
