Why my dragon never arm-waving?

[superyynju]

I have seen many people showing videos of their dragons arm-waving.

I am wondering why my one-year-old dragon never arm-waving to me or other things?

Does every dragon arm-wave to the owner?

Some beardies don't arm wave. My do. But I have a male and female. When my male sees my female he arm waves at her and she does it back.
