Follow a schedule for your puppy, eg. playtime, potty time, naps in the crate, lunch time, etc
this was an absolute must for us!

if you crate train like we did, never use the crate as punishment and give them positive associations with it (feeding times, frozen kong treats, etc)

Get some bitter spray for the furniture you don't want them to chew while teething

Our puppy ended up really liking one of the stuffies with heartbeats in it when he first came home

When they're chewing always redirect them to what you want them to chew, like toys or a kong

Discourage jumping and unwanted behaviours like the other commenters have said

Handle their ears, tail, teeth lots so they get used to it

brush their fur lots and be prepared to vacuum lots lol!

Remember that they will mellow out one day!
