Training tip: Correcting vs. Redirecting
Don't just correct, redirect.
Never just correct your dog ("off"), if you're going to correct, make sure you re-redirect afterwards ("off...come....good boy") and then reward them. The idea is to tell the dog where they can put that energy, and give them motivation to do what you want!
Remember, dogs get better the more they practice - which means they'll get better at that unwanted behaviour too! For best results, redirect them just before they start barking/lunging/jumping.
