<human>: Several days ago my friend's family found a puppy on their front door. It was a tiny little chihuahua and they had no choice but to take it in. They've put posters around and kept it vague so they wouldn't have any unsavory encounters. If they don't find the owner soon the Mom wants to keep the puppy. The only problem is that the chihuahua needs to get adjusted to the six year old Maltese. (Who has lived alone for six years.) Basically this is what my friend told me what was happening. The puppy barks at the Maltese ,but Hiro ( the maltese) does nothing. When the puppy begins to get close to Hiro, Hiro snaps at him. Hiro then runs to his owner. The Maltese is avoiding the new puppy. Hiro is slightly larger than the new chihuahua. Maybe 1.5 it's size.

Condense the text into a few key points
<bot>: We need to get two dogs adjusted to each other. A new chihuahua puppy and a Maltese that has been living on his own for the last six years.
