Long Island police are hunting for vandals who knocked over a 300-pound monument to 9/11 rescue dogs.

The cement statue in a Lindenhurst park is modeled after Hansen, a German shepherd who spent 150 days searching through the rubble of Ground Zero.

In addition to the statue, the park has plaques dedicated to eight Lindenhurst residents who died in the 9/11 attacks.

Retired NYPD Officer Steve Smeldon, who was Hansen’s handler, told Newsday he was perplexed by the damage and likened it to going into a cemetery and knocking over gravestones.

Police weren’t sure whether the statue was targeted or just the subject of random vandalism.

Hansen died in 2004. He was 11 years old.
