Hmmm, I read most of the article. I've never thought of my 5 lb LilGirl as snappy because she is not. She is the most friendly outgoing little dog I've ever been around. She likes everybody. Now sometimes she does bark a lot but usually it is because Annie the BIG dog outside starts barking & that makes LilGirl bark. As for getting on the couch, I WANT LilGirl next to me on the couch or my lap or my shoulder LOL. I love to hold her. Both LilGirl and Annie are friendly and well behaved and I dont think either one of them has any bad habits. Maybe some little dogs are snappy but not mine. Kay in NC
