Kody's about two and a half years old now, although it feels like he's been with me longer than that. But taking him on a walk is a lot easier now. He doesn't bark at random stuff, and I've even trained him to be calm when other dogs bark, which is amazing.
If he sees another dog, he's fascinated, but quiet... unless the other dog moves. It doesn't matter if it's away from him or toward him. He's not mad at the other dog or scared, it's his excitement bark. He wants so badly to interact, but he has no idea how. But the fact that we can be relatively near another dog with some bit of calm is great progress.
Along with the calm I've already described, his is a little more calm about toys and treats as well. He still likes them, but unless it's something really special, he doesn't get too excited.
