Stray Dog
I think your Parent's are doing the right thing by giving the little guy food. Although something to think about, in the event it is on your property, and bites someone, you could get in trouble for that, and God forbid, that the Home Owner's Insurance finds out. We had a dog that appeared out of no where, and stayed on our porch for days. Attempts to find the Owner's proved fruitless, as they were never found dispite all of the advertizing we did, or the trips to the Vets & Animal Shelter. We decided to get it a Rabies Shot to cover our butts in the event it bit someone. Then..we fell in LOVE with her, and kept her until she was 20 years-old. That's an estimate. The Vet said she was 9, or 10 years, and we had her for an additional 10 years. I hope your Parent's fall in love with the dog they are helping. Good luck to you, and thanks for having a kind heart in this cruel world.
