My Westie, Nora, is a whole bunch of dog in a little body, but she loves to be cuddled. High energy which makes her personality very FUN FUN FUN but then can relax in your arms to cuddle. She is a barker though at ANYTHING that makes noise. But that just plays into her personality. My other dog, Cocker Spaniel (Sadie) is also a lovey dovey. But she is more medium build, and actually at the moment a porker!
Just remember, every dog is diffrent and will react to what you do. A little dog is not necessarily a more cuddlier (sp? lol) than a larger dog. Visit a local shelter and see what dog you connect with. You can't get any better with that
