What are some great desensitising activities you can do with your horse? Tarps, poles, pool noodles, gates, bridges?

Bag full of empty drink cans !

I love working with umbrellas haha! That and exercise balls.

Try looking up what they do for police horses! Those could be fun to try, although don’t do the super super dangerous ones that you think will really scare your horse. I know for sure loud noises are on there

Balloons?
