i live on 120 acres of unfenced property, about a week ago during a rain storm this dog showed up at night, i couldn't see him that well until the following morning. what i found was an imaciated, tick covered dog. I took him to the vet for his shots and a check up. He's approximately 6 months old, he has a very sweet temperment, gets along with our jack russell and all 9 cats. I'm wondering if its alright to leave him on a long leash outside when I can't watch him closely and I always walk him on a leash. He is responding to his new name and listens most of the time. Right now since it's raining outside he is in my room with me. any input and feed back on this dog would be greatly appreciated.
