Pomeranian question... can they stand their ground?

Well, every Pomeranian is different, as you know. Your Pom will probably guard her food and toys a lot,most do. But usually small dogs think they are Great Danes! :] I would recommend letting the dogs greet each other at a park. See what happens, if it goes well, try to have them greet at your house. Take small steps. Good luck! :]
