Dershowitz considers his dog, Knuckles, his "son."
In papers filed earlier this year in Manhattan state Supreme Court, Dershowitz said ex-girlfriend Sarah Brega "kidnapped" Knuckles after they broke up.
Brega says Dershowitz gave her the puggle pup – half pug, half beagle.
The Post says Dershowitz has started a website to raise money for the custody fight. For $250, contributors can "play fetch with Knuckles."
The drive is off to a slow start. Dershowitz raised $85 in the first week.
