There are many ways of killing a dog beside hanging him.

The saying argues that a desired result need not be reached by the first, most obvious, or customary method. It encourages looking for alternative approaches when one route is impractical, blocked, or inefficient.

It can also carry a hard-edged sense of pragmatism: the speaker focuses on accomplishing an end rather than preserving a preferred procedure. The image of killing an animal is deliberately harsh, so the proverb may sound blunt, upsetting, or callous outside a clearly figurative context.

Use it figuratively when proposing another way to solve a problem or reach an objective. Because its violent animal-killing image can distract or offend, and may sound insensitive when people or serious harm are involved, choose a plainer alternative in sensitive, formal, or animal-welfare-related settings.
