Wait hold on. Nefja's reactive?
Yeah, to vehicles. I'm doing positive reinforcement but already at the stage where I'm slooowly waning out the treats where she doesn't need one every time but replacing it with a verbal praise.
S-Tier: delivery vans, flatbed cars, car trailers
A-Tier: e-scooters, bicycle trailers
B-Tier: trucks, tractors
C-Tier: bicycles, cars
There are going to be a lot more trucks doing work in our neighborhood soon. I had better start "reverse beep" desensitization for Tris, too. I think he'll still enjoy getting out there to yell at what he can see, but the reverse beeps will upset him inside, send him over from "barking because it's fun to yell" to "stressed out".
He, too, has a tier level but I don't know it as well as you do. My neighbor likes to race him (pickup on the road outside the fence) and I *think* he enjoys that, but the mere sight/sound of a garbage truck sends him into a fury.
