He free ranges with two other fellow silkies and there are 3 older juvenile mutts the free range in the same area. I found him separate from the others hiding under a bit of Styrofoam. He runs as if being chased continuously when I set him down on the ground now and It's been about an hour and a half since I found him. Initially I thought he was attacked and got away uninjured. Now I'm starting to worry it's something more serious. PLEASE HELP. I'm uploading a video currently and I'll post a link when it's done. I got really slow internet.
