She spooks of sleeping dogs that suddenly bolt under her feet, or (ok, this isn't spooking, but she behaves the same way) seeing non-familiar horses when we are on trail. With other things she's ok...
She was afraid of motorbikes, cows, tractors, and other things but it's 2 years from then and she is completly fine with them now, she even doesn't notice it.
Dogs and horses are things I don't know how to desentize her to, she is fine with dogs, until they announce that they are there. But sometimes they just creep from a corner, silently, and then suddenly jump behind her and bark.
And the horses... I think she just has to check if there is a handsome stallion around :P
But I don't like it, cause then she doesn't work at her best.
I won't give her time to think next time this happens :) We'll work hard :P
