Current Status, Part 1

Indoors.
Redirected fear aggression at Annie, at the window. For the biggest/baddest dogs, less so for cocker spaniels, not at all for Buddy or squirrels, unless for some reason Annie gets bonkers.

Outdoors.
Alerts to many kinds of stimuli -- distant dog-barking, low jets, truck or schoolbus engines, garage doors opening, doors slamming, distant voices, especially yelling or screaming children but even normal conversation. Hyper-aware of surroundings.

At the worst -- i.e. if any of these things are near and imminent (across the street, or visible) -- he hackles (but no coyote tail) and "bolts" for home. He knows where the front door is.

If the stimulus persists, but for some reason (ANNIE) I have to keep him out there, he might bolt to the end of the leash repeatedly, then eat grass anxiously.

He will walk with me and Annie as far as just beyond Buddy's house, and if there aren't any scary things, he just wings about. He's very interested in Buddy's front porch, and bushes or trees where other dogs have gone. He doesn't "settle" whatsoever, and at the slightest provocation will try to pull me home.

Also worth mentioning
When he gets to the front porch he seems to relax visibly. He will sometimes turn and try to see the scary thing by going up the porch, protected by the railing.  Inside the railing is "home."
