What Breed Is My Dog?

I picked up this puppy from road. She was in the worst shape. I took her to the vet and they told me that she is 4-5 months old.
She is playful and keeps on following me since she got her trust in place.

She is a quick learner as well. I have adopted her, but it would be great if I can get some idea about her breed so that I can understand her traits.
