Dog in the manger
A dog in the manger is someone who refuses to let others use something they have no use for themselves. The phrase comes from the story of a dog guarding hay it cannot eat, found in Aesop’s Fables.
Where it comes from
The dog guarding the hay
The fable turns on a simple mismatch: hay feeds cattle, but it is no food for a dog. A manger is a feeding trough for farm animals.
In Aesop’s Fables, a dog lies in a manger and growls at an ox that approaches to eat the hay. The dog cannot eat the hay itself, yet keeps the hungry animal away.
In Aesop’s Fables by Aesop
Blocking others without benefiting
Today the phrase describes someone who withholds something without gaining anything from it. It suggests needless selfishness rather than ordinary competition.
In Aesop’s Fables, the ox needs the food that the dog merely guards. That contrast explains why the phrase fits someone who keeps an unused resource from a person who could benefit.

Does dog in the manger mean the same as sour grapes?
No: dog in the manger means blocking others, while sour grapes means dismissing something because you cannot have it. Both appear in Aesop’s Fables, but the dog denies another animal food, whereas the fox belittles fruit it cannot reach.
Can someone be a dog in the manger without owning the thing?
Yes, control matters more than ownership. Someone who can block access to an unused room, tool, or opportunity may act like a dog in the manger even if it belongs to someone else. The point is needless obstruction, not legal possession.
