She's still quite reactive to trucks. Getting better, but she still gets high-headed, tense, nervous, and sometimes just blows her top completely. The odd thing is, cars don't bother her. Anything bigger than a car is terrifying.
I am looking for more advice on how to handle this. One afternoon I plugged my headphones in and sat at the end of the lane with her; every time a vehicle passed, I gave her a treat. That did seem to help quite a bit. Once the grass comes up, I'll try hand grazing her in the ditch by the road as well.
The traffic around our parts is usually few and far between.
What else can I do to get her over this fear?
