I like bitting hair/fur!
Ever since I can remember I've like bitting people's hair, animals fur and my own hair. I like the feeling of it but I think I do it more out of love. Every time I'm away from my dog and come back home I bite her fur in the side of her cheek and let lightly shake my head. I don't hurt her and she doesn't seem to mind. But my family members get weirded out when I hug and bit their hair. It's like I have some urge to just love them so much. Why do I this? And is this normal?
