(Portland, OR) -- The Oregon Humane Society has taken in more than 30 dogs from a suspected puppy mill in California. In all, more than 150 dogs were living in cramped crates, filled with waste. Many of the dogs need medical attention. They are French bulldogs and other bulldog mix breeds. The Oregon Humane Society says it'll be several months before the dogs are ready for adoption. They'll go to foster homes to recover and learn how to be a pet. The dogs will be put up for adoption as they become ready.
