helping a stray dog on the soi safely

There was a small brown stray dog near our soi in Bang Phli, quite skinny and limping a bit. I was scared to go near him at first because I do not know how they will react. Kaprao is my Shiba Inu and he was barking at the fence, so I took him inside first. What I did: I sat on the ground, far enough away, with some chicken in a bowl. I did not look at the dog directly and I did not reach out. After about 20 minutes he came closer. I put the food down and walked away. The next day I put a towel in a box near the wall and he slept there. Then I called the local animal rescue group that comes around our area, and they came to check him. If you find a stray, do not take it inside alone unless you are sure it is safe, and always use gloves or a towel for the first time. The rescue said it is better to call them than to feed the same dog every day without a plan.
