This dog was found in our neighborhood and I have gradually calmed him, I have worked with many rescues and understand how to work with them so we could identify his personality. I brought him into our fenced in yard. He has a sweet personality once he has bonded to you. He doesn't bark and doesn't appear to be overly aggressive at all. He gets along with my two older dogs who are the same size as he is and the 6 lb Chihuahua we have. We have kept him outside but he seems to be used to being in the house. He has been in the neighborhood for about 3 weeks, here for 1 week. He would be good in a large yard or on a ranch.
