The expression "a dog in the manger" is used to describe someone who selfishly prevents others from benefiting from something that they themselves do not need or want. The original context of this expression comes from a fable where a dog laid in a manger, preventing the horses from eating the hay even though the dog had no use for the hay.For example, if someone refuses to share a resource with others, even though they are not using it themselves or would not benefit from it, they could be described as a "dog in the manger." It is a way of expressing the idea that they are selfishly preventing others from having something they could use.
