I would like to be able to pet him when I encounter him!
I also think to try to shoot him... but I'm not able to try it, I hate hurting animals, even in games. I think, once, I shot him, just to see and it's not possible to kill him anyway, like the folks town, he just turns around!!! That reminds me that I did not like the first sequence, after the car crash, finding this poor dog killed. Today, I was trying to meet the giant dog and try to see if York can shoot him, just to see if he can be killed... However, I'm pretty sure, he will kill me before. But, as my car was too damaged, I even had the time to go out from the car, lol, I finished at the hospital with a 140$ penalty!!!
BTW, I love this game, it's a drug for me!!
