We have an 8 week old puppy (3/4 Black lab,1/4 Beagle) and we didn't even think of crate training. How is this concept of training used? Is it used for discipline, or house training, or anything? Our puppy is doing pretty good as far as papertraining goes, but she is really hyper and chews and nips at people. Could we use crate training for this problem? She already goes into a little crate on her own sometimes, to sleep. Maybe we should consider using the crate more often.
