Magistrate Judge Mark Smith ordered Dahl, 23, to serve five days behind bars over the holiday each year.
Dahl pleaded guilty to inhumane treatment of an animal under a plea agreement with prosecutors that included misdemeanor charges from three other cases. He initially had also faced a felony grand theft charge in the Dually case.
Dahl also agreed to pay $25,000 in restitution to horse owner Wendy Halweg for Dually’s injuries. Halweg, in return, agreed not to sue Dahl, but she said Dually will never compete again.
