Labrador training: Tips/Help needed please!

Howdy guys and dolls,

We got an 11 month old Labrador that is a rescue. She knows sit, stay, and shake already. Oh, also she’s house broken and crate trained.

We got her because she’s a good sized dog and family friendly.

Here’s what we need help with:

Alerting.

Any odd noise that’s close to the house, any knocks on any doors or windows, any suspicious noise? Bark like hell.

She’s pretty laid back so I need tips.

Understand: we’re not trying to get her to attack anything unknown necessarily, we just want her to give a loud vocal alert / bark.

TIA!
