Rain and the soi dog in San Sai

Please allow me to share a story about our Rain. Last month, while walking Rain near the rice field behind our house in San Sai, I discovered a small soi dog lying under a tree. It was very thin, and one of its back legs was swollen and bloody. The dog did not run away, which was surprising. It only looked at us with tired eyes. I am not an expert on street animals, but I could not leave it there. Rain was very curious and gently sniffed the dog. It was a good sign, I think, because Rain is usually not friendly to strangers. I carried the dog home in a towel, which Rain watched carefully, as if he understood the situation. The next morning I took the dog to a veterinary clinic in the city. I will not give its name here, but the doctor was very kind. He said the leg was infected from a cut, maybe from a fight or a fall from a motorbike. He gave antibiotics and cleaned the wound. The dog stayed there for one week. When I visited, the dog's tail was moving slightly, which made me very happy. Now the dog lives in a shelter run by a local volunteer group near Mae Rim. They are looking for a family, and they told me that a dog like this will be easier to adopt if he is trained and healthy. I am thinking very seriously about this, but my wife is not sure yet. We already have Rain in the house, and he is a lot of work, so it must be a careful decision. Rain is still a bit jealous when I talk about the dog. He keeps looking at the door as if waiting for his friend to come back. I will try to bring them together for a walk next week, if the volunteers agree. I would be grateful for any advice from people who have rescued soi dogs before. Thank you very much for reading this long message.
