found a lost dog in san kamphaeng, what I learned

I was walking back from the market in San Kamphaeng at night when a dog came out of a soi and just stood in the middle of the road. Medium size, brown and white, with a red collar but no tag. I thought it would run away but it followed me to the gate of my building. Here is what I did, in case someone else finds a lost dog. First I took a photo and sent it to the local Facebook group for the area, with the place I found it. Nobody answered for the first hour. Second I asked the security guard at my building if he knew whose dog it was. He said it came from the house at the end of the soi, and the owner had been looking for it since the afternoon. Third, I did not give the dog food from my hand, I was scared he might bite. I put water in a plastic bowl and waited. It took about 40 minutes until the owner came, a young woman, she was crying. She said he is 2 years old and he never ran away before, he just got scared by fireworks from a wedding. Some things I learned. Check if the dog has a chip, ask a vet to scan it. Do not post the full address in public groups because that is risky. And keep a photo of your pet on your phone with a date, the owner needed that to prove he was hers. I was not a hero, I just did not want the dog to be on the road at night.
