We found a yellow lab

Good morning,
We found a yellow lab at our house on Ransome St. in Port Allegany this morning.  We actually saw him running down Main Street last night and he showed up at our house this morning.  It is a male dog and he looks like he could be a puppy.  He is skinny and was very hungry.  We are keeping him in our house right now out of the cold but would like to find his owners.  I was hoping an ad could be placed letting someone know that he was found.  I can be reached at 642-7596 if you have any information or if someone contacts you to inquire about this dog.  Thank you very much, I appreciate any help you can give.  God bless.
