A pitbull was tossed from the roof of a Bronx building Tuesday morning and died, police and sources told The Post.

“There’s a dead brown pit bull,” a 911 caller told police around 10:30 a.m., adding that the dog had been tossed from the roof of 108 Clarke Ave. in West Concourse.

The pooch fell six stories and landed in the courtyard below. It was pronounced dead at the scene, police sources said.

No arrests have been made, and police are still investigating.
