Hi,
When you as a player become a dog, using selectPlayer for instance, the camera will be very low in both 1st and 3rd person, even clipping with the model.
Additionally, as an animal you're only able to look around using numpad keys, double tap alt doesn't work.

I don't recall these problems being present in ArmA 2.
