Nancy, welcome to the forum. Your new furbaby is gorgeous. I can see why you picked her. My Shelby has an underbite and it hasn't caused her any problems.
Welcome! There are a lot of us in southern New England. (and SE MA)I'm a newcomer to the forum and to parenting a havanese. Picking up my 12 week puppy, Lily, in Rhode Island tomorrow. I was informed she has an overbite, so I'm glad to find these reassuring posts, since I didn't want to have to wait another 6 months or so for a pup. Obtaining a pup has become a lot more difficult since the pandemic!
