What type of body language do alpacas exhibit to show dominance?

Mars V, indeed they do! Let's not forget, they also tend to have lots of hamstring injuries due to lack of proper training and stretching.

It’s a bad habit they pick up from watching baseball. They also scratch their groin and pick their nose.

Is that why some men spit a lot?

James,. didn't know that cows stick their tongues out on purpose, it could be it was only tasting the air. or perhaps just licking it's lips!
