Small mix breed female

We found a small mix breed female dog.
and no one has claimed her and it's been a month now.
We have two dogs and they don't get along with her all she wants to do is play.
We can't afford to take care of a third dog at the moment.
We are looking for the best home possible for her .
She is utd on shots and not fixed she only weighs about 15 lbs at most No fee just want her to go to a great home she is a very playful and loving girl Serious inquiries only no scam no codes Also don't say check with shelters we already did that and they are all full
