A Bronx man has pleaded guilty to abusing his puppy.

Prosecutors say 25-year-old Roberto Martinez slammed this puppy to the floor last September when she was 8 months old.

She injured her leg so badly that it needed to be amputated.

The puppy, named Sally, has been relocated to a new home.

Martinez pleaded gulty to a charge of aggravated cruelty to an animal, which is a felony, and must register as an animal abuser with the state.

He will be sentenced November 15.
