Head of Barking

Fly, aka “Fly la Mouche“, is Kliber’s mascot. Fly possesses Olympian swimmer skills and could have followed his parent’s footsteps to become a great hunting dog but he chose instead to stay with his master and spend most of his time sleeping on fluffy pillows. When he is not being pet, Fly likes to chew on plastic thingy and send his teddies flying in our open space.
