I have a 3 year old bull that acts strange sometimes. He will be lookingstraight ahead with head down and kinda like in a trance, blowing and puffing a little, then he may drop down on his front legs and dig dirt with his horns and rub his face in the dirt. He will create quite a dust storm for a few minutes, then stop. Would there be any thing wrong with his ears maybe? He appears to be fine otherwise. Any ideas? Just want him to be ok. Thanks.
