Can I just say, WAY OFF TOPIC, This is the most beautiful dog!I think keeping them on a leash and slowly putting them through the stimulation until it's no longer that interesting for them...I had mine on a leash (a short one) made her sit/lay down and put some chicks near her. She would shake...I would wait. With repetition the tension in her body and the shaking subsided pretty quickly. Then I moved the chicks in....then she was aloud to be standing...then sitting without a leash...etc. Slowly move towards the dog being with the chickens independently when you see that they are no longer fixated on them. With repetitions it's no longer that interesting for them, it just becomes whatever.
I think the dog's personality is huge on how quickly they learn. My Pitbull mix has a desire to please me (the 'Alpha dog') so much that if I say stay, she will not move even if you put a steak in front of her. So she was easy to train...
During training...stiff as a post!
Example of how this dog just does what I say...you want me to hold this chick on my nose?
This is her after training...she just lays with the chicken...and they want nothing to do with her, hahaha.
