What does it mean when BD closes their eyes while being petted?

[luvmybd]

I thought it means a BD is enjoying being petted.
I did read the contrary. It said it means a BD is tolerating but not necessarily liking the attempting to show affection.
Any thoughts?

It depends on the dragon , some do it when they are content, others when they want to ignore you. You really just have to learn your individual dragon.
