Lost dog, Curl Curl — male rescue dog with a deformed back paw

Butch escaped our enclosed yard during the storm. He is a flight dog not a fight dog. His collar has broken off. He is a rescue dog and very skittish of everything including people, shadows, loud noises… But he does like playing with other dogs. He doesn’t bite and rarely barks, he is full of love and kind. He has an old injury (broke his femur) so his back paw look like it’s a little deformed but it doesn’t stop him getting around and running. He is black with brownish eyebrows, paws and around his mouth. Some white hair from his head to tail with a patch of white in the middle of his tail.
