Puppy Training Tips

I have a puppy of 5 months Australian shepherd, training tips for this race?
She barks to go outside, which is good for us, but also barks thinkgs others, it is too. We have disciplined her and helped some, but not the whole way. What is more intelligent personality and thus I know it goes with race. Training Any advice would be appreciated. Thanks!
My aunt Aussie races, with seven of their own. Its all about how to play with them. And yes, when ringing the doorbell, they are all the crust. They are bred to be strong. They are the sheepdogs. So what we have done is to give a command to talk. (But) We use the book "Speak" Well, the crust. we also say "what?" reference for them to do stronger. I love this game, but its very common for its bark.
