Hi, I re-homed 2 boxers (they're 5 & 2), and have been clicker training them for 2 months which is going well. A current problem is them barking at the neighbor when he goes down our shared driveway to get the newspaper in the morning (I have a hidden fence). If they see me at the doorway, they'll generally come back straight away, but if I'm in the shower, they'll continue to bark - which isn't ideal for him or the other neighbors! Any ideas on how to stop this? Should I arm the neighbor with a clicker? treats? Or only let them out when I'm able to be present to reward them for not barking?
Thanks!
