What he got caught for seems to have been just the tip of the iceberg. He had five dogs, and the neighbors were apparently reporting abuse before the incident he got caught for. So it probably isn't "one mistake" it's several mistakes over time, involving abusing dogs.
According to a Clackamas County Dog Control report released Thursday, Woods in April registered five pit bulls: Hollywood, Brock, Gangsta, Sugar and BB. Officials have refused to say how many of the dogs are missing.
According to Clackamas County Animal Control records, neighbors called twice in January to complain about animal neglect on Woods' property.
Two months later, animal control received an anonymous call that seven pit bulls had been left outside without food or water and that two small dogs had been eaten by larger dogs.

Woods' "caretaker" also plead guilty for first-degree animal abuse.
