Of course not! The nature of both her and the cow resulted in the kick.
My very first Dobie, Amber, got kicked by my horse, Lucky. Thankfully, Lucky was barefoot and she hit Amber in the side of the neck, not her head. Amber was still flung back about 10 feet. She ran off yelping with her head twisted about 90 degrees. I about lost it right then and there. I managed to get her in the truck and raced her straight to the vet, appointment be damned. By the time I got her to the vet she had her "head on straight" so to speak. The vet did a cervical exam on her and looked in her ear. She said she had a hematoma in the ear but that seemed to be the extent of the damage.
6 years later, the true damage finally showed itself. Amber would be sleeping peacefully in the sun in front of my patio door then suddenly jerk awake and upright with one or the other front leg out stiff while she screamed. Similar to what was happening with Ben just before I had to let him go.
Amber was treated with a course of Prednisone and was never taken anywhere in anything but a harness. She had no more incidents of nerve impingement and muscle spasms after that one steroid treatment. She lived another 3 years before hepatitis took her.
