Doesn't Care From Hearing

[NivAndBlu]

So recently, I was making noise, I even did a loud "OOOOOH" noise to my bearded dragon, but he just stood there. Can you guys tell me why this bearded dragon doesn't care about ANYTHING loud???? :? :? :? :? :?

IMO dragons will put on a poker face. Making sounds for communication must be quite foreign to them. Aside from hissing there don't purposefully make noise. Poker face because he has no reason to respond, maybe
