i got an 6-9 month old pitbull puppy a little over a ago, he was found abandoned by friend a month ago, and she couldnt keep him so i took him, he does great with me, but everything and everyone else he cowers away from, i mean he is scared of the door, people, especially men, lawn mowers, bikes, this couch that is on the sidewalk on our way on a walk. im especially worried about people. is there any advice on how to socialize a older puppy, who i dont think was socialized before or treated very good? any suggestions would be great
