I want to take my beardie to the pet store when it warms up. All winter he's been cooped up indoors because of the -30 celcius weather. Today it is +6 degrees. Would it be ok if I put him on a leash, wrapped him in a blankie and brought him to the pet store for about 20 minutes? He would only be outside for a few seconds. I want to get him used to going places while he's young.
