I think the best thing would be to adopt a little dog from the pound and give it a loving home.
Otherwise you might consider these. Ive listed their average height at the shoulder and weight so you can judge how big they are. Ive kept away from the breeds with similar looks to the ones she doesnt like.
Good indoor dogs:
- Tibetan Spaniel ( 25cm , 5kg )
- Cavalier King Charles Spaniel ( 30cm, 6kg )
- Miniature Pinchser ( 28cm, 5kg )
- Papillon ( 30cm, 4kg )
- Pomeranian ( 28cm, 2kg )
- Pug ( 28cm, 7kg )
- Toy Poodle ( 25cm, 6kg )
Possible indoor dogs although they need more exercise than the previous and would probably appreciate a yard to run around in :
- Staffy ( 38cm, 14kg )
- English Cocker Spaniel ( 40cm , 13kg )
