I have also learned that you can have really big dogs living in the same household with really little dogs. Bella is 50 lbs. and Ripley is 15 lbs. but there are some really big size differences here on PT. Before seeing WELOVESPUPPIES' Champ and Duke with Chopper, and Kimlovescats' Bear with Betina, and Anna's Bon with Simba, and some of the other big/little combinations on here I would have thought the sizes might be too extreme. (Do I dare think about having a chi some day? )
