german short haired pointer charging

[blaster1985]

Hello everyone, we have adopted a 2 year old GSP and she's fantastic except in one way; she charges the front gate of our yard whenever someone walks by. She has a very loud and intimidating bark that startles passerbys and we would like some suggestions on how to inhibit this behavior. She seems to want to alert us to some intrusion, that is not necessary to us, but we don't wish to become the annoying neighbors on the corner! We appreciate all ideas and thank you in advance!
