I need help. We were at an art fair this weekend, and every dog he saw he would bark uncontrollably until the dog was no where in sight. He also does it when I take him out for a walk. I try to stop him, but I don't know how. I find myself trying to not let him see the dogs so he wont bark. Then yesterday I was in the backyard at family's house and a bird was making its sound and he just barked like crazy!! He also barks at everything he sees out of the window, squirrel, possum, bird and anyone walking past. He just started this a month or two ago. Im assuming some of this is normal. He's still a puppy, 9 months. Ive had him since November. We just started going outside in March because the weather here was too cold to take him out. Will he grow out of this once he gets used to being outside more? Any advice is greatly appreciated!
