Toby is afraid of his shadow and shadows in general. Sounds weird but true...some days are better than others but he'll usually bark at his shadow most days.
He's also afraid of his brother...Henry...a tortoise, whose about the size of my palm. When we put Henry down on the floor he barks and barks. Its so funny bc Toby could easily hurt Henry not the other way around.
But most things you would think he would be afraid of he could careless about...especially loud noises like fireworks and such...they don't even phase him.
