Has anybody heard of a dog being afraid of the dark? My four month old Lab is fine in the dark if somebody is with him but if you leave him on his own with the lights off he just crys and crys, If you leave him alone with the light on he is fine on his own, he will go to sleep and you won't hear a peep all night. Is there anyway to change this or should we just accept it and leave the light on to keep him happy. :)
