The stray dogs need to exterminated or have them breed in a different habitat like a zoo. Leaving them on the street means exposing humans - who are on the streets either late in the night or early on the morning - to dog bites. Most of these dogs are also carrying some or the other disease. Also, they assume the role of wild dogs by persuing in packs. They even follow bike riders or even cars. They definately need to removed from the streets to make the roads safe.
