So, I have a bearded dragon named Neo and as I was watching a show on my laptop I hear some hissing and the only think I could think of hissing was him. And while watching my show, i could hear him moving a lot. When I went to check on him he started acting very territorial and puffing up which has never happened to me as he is normally very calm and is ok with me picking him up or simply petting him. he is also typically a very fast sleeper and falls asleep once I turn off his lights. Which is why I am slightly concerned and wondering if this may a sign of something.
