I have a mini pig who is 2 years old...well they said she was a mini when I bought her. She's 75 lbs. She just recently has had 2 episodes of what seems to be a seizure I think? I'm not sure that its a seizure though because she doesn't shake or tremble like most seizures are described as. Instead, her whole body stiffens...her legs go out straight and her hooves curl. (So much that it looks painful) Her tail curls back towards her back and she breathes very fast. It lasts about 2 min. In that time if I try to move her, her body is completely stiff and her eyes are open but she seems totally out of it. She also makes little whimper sounds like she is in pain. Anyone ever heard of something like this? I'm very worried.
