I hope you at least try to find the owner. It did have a collar on....someone might be looking for it. My dogs get out and run off now and then, doesn't mean they are abandoned. Of course I have learned to put my name and # on their tag. Check with the local pound and spca, etc. Usually people looking for their lost dogs check there. Good luck finding its home....and if you don't, hopefully it will be a good dog for you.
