Hey everyone, new addition, need opinions!

Hey everyone!
I know it's been a while, but I figured I would dtop by an introduce my new addition, Daisy. She is about 6 months old, and I have no idea what breeds she has mixed in her! I was really hoping she would get huge, but at this point, I don't see it happening. She is only about 30 pounds, and hasn't grown any in about a month or so. My vet originally told me she was a dobie mix, but she is so small, I'm just not sure. She has no bottom teeth in the front of her mouth, and I found her deserted on the side of the road. I'm going to try to add a picture here, if I can remember how!
