Dogs are known to be quite brave and curious in nature. However, the dog you are about to see in this video whose name is Lexi is afraid of a duckling that is quarter his size. The dog initially is standing looking at his parents when he is introduced to the duckling.
At first he just ignores her but when the duckling approaches him, he suddenly gets scared and you see a grown dog running scared of a mere duckling. The duckling gets braver as Lexi gets scared and starts following him around the home with the dog back pedalling as fast as he can.
