Congratulations on the success! Yes, crate training is amazing. In fact, it works just as well on an older dog who has never been properly housebroken. When my son married his wife she was the owner of a cute Pekingese. He was 2 years old and was still having mistakes constantly. I gave her the crate that I had used on my miniature poodle and immediately PRESTO no mistakes for this little guy!
