A buffalo will do anything to survive. They'll dig through snow to find grass while a normal cow would just stand and starve to death. They hate anything small, especially dogs. I've seen buffalo bait a dog by acting afraid for just one chance of killing it. I guess this comes from the days of wolves chasing the herds.
Buffalo also protect each other.
You can stand on the side of a field, hold up your hand and start moving your fingers. The camels just have to come over to see what you're doing. And they're very funny to watch as they run. They're double-jointed, their legs go in every direction and they move that long neck as they go. Our house has never been boring.
