You might remember hearing about Marco Washington, the 19-year-old boy who was seriously injured a few months ago.
He ran into a moving car, trying to get away from a pit bull that was attacking him.
Now, the dog's owner, James Moore, has been found guilty of possessing a vicious dog and failing to register the animal.
He could pay $500 for each of these offenses.
A sentencing hearing is set for September 5.
