We let the puppies out for the first time we set up a couple of fire guards in the sun and took the puppies out, however the sun moved, so we moved the run and the puppies. Then 5 minutes later the sun moved again. Thepuppies were getting too cold in the shade so we carried them to a new spot without the fire guard. the all huddled up at mums feet because she was picking them up and putting them in her jersey. they werent out for very long though.
