Yes we are responsible dog owners, we have a fenced in yard he can not get out. He is not around intact female dogs unless there may be one at the dog park. He is a very good boy. We have other male dogs that come to our house and mark, and Diesel just smells it doesn't mark over it or anything. He still pees like a girl as well.
My only concern about altering him in anyway, is his temperament. He is a great family dog, I am his chosen person. He is great with our 6 year old son, protective when he needs to be, but very sweet and friendly; and I would hate for that to change in him. He will be 18 months in Feb. and that is when we had talked about getting him neutered (if were were).
