Hi, I'm new to this forum. I got my bearded dragon about a month ago, his name is Rocco and I think he's a juvenile. He was given to me by a friend who got him at a Pet store. At first he was very friendly and let me pet and pick him up, (this lasted about a week to a week and half). Since then he'll still let me pet him, but if I try to pick him up and runs away and won't let me near him. Any clues as to why he won't let me pick him up? Or things to try to help him not want to run away from me?
