IMO if you want to take this on, you need basic commands....treats...and lots of time for progress, and positive affirmation to the animal. Training will help him understand he's not the boss....I'm not a pro on this, just trying to help. Get some hard rubber chew toys and bones instead of fluffy stuffed animal toys.
Kenneling will help the animal socialize with other people and other animals. Bailey had good points to heed.
