I was lucky with Katsu - I got her at 4 months because the breeder held her back for a SAR home (only to change her mind on it later). She came crate trained, and didn’t not landshark me.
She did, however, chew on things I’d prefer she didn’t. I did ge redirection method. “No” or “Uh-uh” for the thing I didn’t want her chewing on, offer something okay to chew on, and a “yes!” When she took it. It seemed to work pretty well with my Shiba Inu when he was younger.
