Lyndhurst - lost dog?

For some reason my post keeps getting removed by the lyndhurst facebook page, but there’s been a brown dog, very skinny, walking through backyards lately. I think this is the same dog as last year, which really concerns me. I try to feed it but it’s very skittish and runs away. I believe it still has a collar, but I can never get close enough to see a tag. I see it around Thornbury, Spencer, and Irene a lot. It is light brown, medium-sized, looks kind of like the attached pictures (I haven’t been able to get a picture due to the aforementioned skittishness). Is this anyone’s dog? Should I try harder to catch it or is it just a frequent runaway? If anyone has tips for how to get the dog to trust me enough to get close that would also be great.
