Found stray dog and the owner is MIA.
I reside in Queens County, NYC and a stray dog arrived on my porch 2 days ago. I took it to the vet and found the owner via microchip, attempted to contact them at two phone numbers (both disconnected) and emailed the email address of record as well as posted it on my social media and the local social media page. What do I have to do to formally adopt the dog if no owner shows up? And how long do I have to wait? Is there a formal process? Any helpful advice is appreciated, thanks in advance.
