John Fleet III pleaded no contest Friday in Common Pleas Court to animal cruelty, child endangerment and corrupting a minor.
Fleet, of the Oxford Circle section, admitted to pouring rubbing alcohol on the pit bull puppy then setting it on fire.
The dog was badly burned in the January, 2010 incident but survived.
Fleet was sentenced to 2 to 7 years in prison.
He has also been ordered to stay away from his children.
