Someone ABANDONED this poor dog

Someone abandoned this dog near my house. The home owner saw a man throw it over a fence and into their back yard then drive off. They posted about it on facebook and I went out to find it. Sadly the dog doesn't trust me enough for me to put a leash on it or take it home but I'm slowly gaining the dogs trust. Hopefully I'll be able to catch it in the next few days and I might just keep it.
