mixed puppy growth

Question
I do rescue and always concerned about how I present what a dog will be full grown. When you have a cute little black puppy with white feet and neck and smaller ears, lots of questions come up about breed and size any hints?

Answer
I am not sure what your question is here. A black puppy could have anything in it from poodle to rottweiler, depending on the body size, shape, tan color on eyebrows,etc.
All black with some white I would lean toward a lab X. Most common mutt out there it seems.
