The answer is likely "the worst of it".
Here's why:
* Literal meaning: If a large dog fights a small dog, the smaller dog is likely to get hurt more severely.
* Figurative meaning: This phrase can also apply to situations where a powerful force (like a large corporation) goes against a weaker force (like a small business). The smaller entity often suffers the most negative consequences.
