entre chien et loup

[busker]

 if this poem was titled "Domestic Abuse" how would that change what you think about when you read it?

Domestic abuse is implied in the poem, and making it the title would be an insult to the reader's intelligence.
Even without knowing the French idiom, the dog / wolf symbols are apparent, and don't need to be explained further. The full import of the idiom might be appreciated better by a French speaker, but there is enough here for a translation. Not all foreign idioms translate so readily, of course.
