Chewie s so adorable and such a calm puppy. He only weighs 5 lbs and will not get bigger than 10-11 lbs. He is also playful and minds well. He is paper trained but also goes outside. My dog is jealous and doesn't like the puppy. So sad as I wanted a playmate for her. Maybe because he is a male and they don't mix well - not sure but I have to sadly let him go.
