Neighbors complained about a foul smell in December.
Animal care officers could not believe what they found inside. There were 33 pit bull mixes living in their own excrement. Some had been used for fighting, others for breeding.
"The staff was really, really moved by this story. When they went in the smell was intense, the conditions were intense, I mean some of the staff members got kind of emotional over it," said Oakland Police Sgt. Dave Cronin.
Some dogs had rarely been outside their crates and had trouble walking after they were rescued. Others had to be euthanized. Others have adapted well, and are awaiting adoption.
The owner has been charged with felony animal cruelty.
