The proverb "When the pig has had a belly full, it upsets the trough" is from

A Dictionary of English and French Equivalent Proverbs and A Dictionary of English and Italian Equivalent Proverbs by Teorod Flonta.

Does anyone have more information about this old saying?

but mostly:

What does it mean?


According to Charles H Spurgeon in The Salt Cellars:

When the pig has a bellyful, he upsets the trough.

Which is very malicious of him; but wonderfully like a pig. May not others feed also? What harm has the trough done[.] We know evil persons who spoil the trade by which they have lived, [and] thus knock down the ladder by which they rose.

This refers to people who have benefited from something (like the pig's feeding trough) who, after enjoying their benefits, spoil it for others. The allusion is to pigs who eat their fill, then cause the trough to spill its contents so that other pigs can't also eat from it.

  • It would appear so, but going beyond just wanting something for themselves to wanting others to miss out. – Lawrence Apr 3 '17 at 18:56
  • Some sources call this a German proverb. E.g., James Lawton, The World's Best Proverbs and Maxims: Gleaned from Many Sources (1937) has "When the sow is satisfied she overturns the trough." I found a 1919 source with that wording.... – Sven Yargs Apr 3 '17 at 20:05
  • ... Spurgeon's Salt Cellars, however, is even older, having been published in 1889. – Sven Yargs Apr 3 '17 at 20:06
