I recently have aquired two Quarter horse/ Draft cross horses, They have been wonderful, lovey, mellow horses, great with kids..ect..however today, myself and a 9 yr old girl were out visiting them in the pasture and the mare struck out at me with her front hoof for no apparent reason. She was half asleep while we were petting her. I stopped for a moment to light a cigarette and she struck out with her front hoof and knocked the lighter out of my hand, broke a blood vessel in my finger, and came too close to hitting me in the face. I immdiately got after her for it (got her moving) but now am very concerned that it may happen again... I have kids and I have lost that trust with her. Why would she randomly strike out at me? Could it be jelousy over me not petting her? Was she angry I was talking to the child? Is it testing my leadership? Or.... does she want me to stop smoking..lol???
