Vega will put any and everything in her mouth. She plays with the brushes when I groom her. If I have her stall door open a bit and there's something out there (lead rope, halter, saddle pad, reins, saddle) she'll try and eat it.
She also loves to just chew on sticks and wood chips. She doesn't run away from me, but she'll grab something when i'm not looking and when I do look at her, she stops everything. She can be a goof sometimes.
She will also close her eyes so I can get her eye boogies out. When she was sick, I would clean up her nose and she's just stand there. I also had to remove some stuck on snot in her nose. I could tell it hurt her, but she stayed there.
She also love her chin being scratched. She'd rather have that scratched than anything else.
