so i have 2 male tegu's one 2ft the other 3ft. recently its been nice out in new england so i have been taking them outside to get natural sunlight but i noticed that my larger one turns into a nut when hes outside by himself tail whipping and hissing trying to run off and attempting to bite me so obviously he doesn't go out as much since its really stressful on both of us. but my smaller one i take out alot more often but even the first time i took him out he was perfect he walks in circles around my front yard and if im sitting in the grass he will come up to me and lay on me or go check out my dogs and never acts up. but its not like my larger one has any of that i make sure to sit in reaching distance in case he decides to bolt and my dogs arent around and we are in a seperate part of that yard.I'd really like to change his attitude taking him outside because as soon as i go in the front door hes him old self again, could it be all the smells? if so why doesnt my other tegu freak out?
