i know my dum is very calm and not head shy at all! i can do amost anything to her and she doesnt even flintch. I went to a show yesterday in taylor, and a guy had 2 or 3 four foot dums. i asked to see one since mine is only 30 inches. they were alot different than mine. all snakes are different. like they said before. he was probably all stressed out and a reptile show does not smell like a normal show that you would do does either.
