I will admit to being totally taken a back at Mozzie's sudden nippy behavior (he has been perfect for months) until later than night when I couldn't sleep and I started replaying the incident in my head.
It was then that I realized that I never offer to play with Mozzie like my brother in law had started to do.
I do not play with my horses. Never have and never will.
I love my horses, and freely give scratches and butt rubs, but I do not find any joy in a horse chasing/following me.
In fact I hate it when horses are behind me. I always catch them making ears at me. I am the boss mare and I push them instead of the other way around.
I do not touch muzzles unless I am grooming, deworming, or checking teeth. I do not allow noses any where around me and any attempts at nuzzling are punished immediately.
I am a person and people are not be played with. End of story.
Foals grow up and I do not want a 2 year old 800 lb Mozzie looking at myself or at his 2 year old 30 lb human sister thinking that he can play.
The problem with playing with your horse is that you can not sit them down and explain when it is okay to play. That it is okay to play with the BIL but not with the baby.
And since I can not explain when it is or is not appropriate to play I choose to not play with my horses.
