Don't give up on him. He's too cute. It most likely is from when he was a pup. He may have very well had to fight with others to get food. We have a pup that went through a house fire while caged. He
is very timid and spooks easily, but is adopting well. He is glued to my wife for security. Certain noises like a vacuum scare the living hell out of him. We have to be careful. Eli is registered and pure
bred. It happened when he was very young. Helix will be fine. It takes time.
