Dog barking immediately when guests enter the home

Dog’s current state:Alert → quickly escalates to barking and forward movement
Environment:Inside the home, usually at the front entry. Happens consistently when someone walks in.
What’s been tried:Asking for a sit before guests enterUsing leash guidanceVerbal corrections after barking begins
What happened when tried:Dog can hold position briefly, but breaks as soon as the guest crosses the thresholdCorrections seem to increase intensity rather than reduce it
What I think might be going on:Possibly threshold sensitivity + anticipation rather than disobedienceFeels less like “not listening” and more like “can’t stay regulated”
What kind of help I’m looking for:Perspective + better way to approach the moment before the guest entersHow to reduce the intensity at the threshold rather than react after it starts
