Drop them off at a temple they will come right.
lots of temples around Hua Hin have hundreds of dogs dropped on them , they then become better fed soi dogs, but still soi dogs, they should be sterilized, I thought this was the plan a few years ago but there's still thousands of them around, where I live they wake you up in the early hours of the morning howling and barking, then they sleep on the road all day. Someone drops buckets of rice all along the road side just about every day, seems to calm them down a bit, although some are so mangy they should be put down at a vet, it would be the kindest humane thing for them.
