Gradually intro duce her to these things in small increments. For example, for the horse...
-Run the hose and walk her near it
-Run the hose and walk her closer to it
-Run the hose and walk her through it
-Run the hose and stand her near it
-Run the hose and stand her over it
-Then, hold her and introduce the hose to her hooves. Once she no longer stomps/spins/throws fits then take the pressure off and put the hose on the ground. She shouldnt do this too long because you had gone through the earlier steps and she was ok with them.
Do the same, gradual introductions to the clippers and mane pulling (Although I would just band it like a WP horse and not pull it.) Only advance to the next step when she is ok with the earlier step.
