We always try to redirect. He has lots of toys, but there are times he just wants to bite. This is not chewing, this is biting hard. We only use the crate when nothing else seems to work. We don't like doing it, because we don't want him to associate the crate with punishment. He's a toy breed (papillon) and sleeps in his crate at night. He's 15 weeks old now. Don't get me wrong, he can be soooooo sweet and loving. He's the greatest - he just has his moments. We really hope it is just a stage.
