So I don't know much about Tucker's past other than he was in a family with a ton of kids. But when you hug him or get in his face he's a big licker but he'll even crawl up on you and nibble your ear lobe! He won't bite it or anything hard but he'll go right for it and nibble. It's so cute! Does anyone else's do this? I wonder if he was taught this or what??? I wish I knew more about his past. I think he knows more things that I'm not seeing.
