It’s less about the particular dog and more about the relationship you establish with the dog. The dog has to understand that it’s in his interest to defer to you. That doesn’t mean that you have to be stern or forceful. It does mean making it clear that what you want matters, and that the dog’s life gets better when you’re happy. It also means making it very clear what kinds of behaviors make you happy.
Clicker training is a great way to communicate to the dog exactly what makes you happy. If the dog is at all treat-motivated, they get the hang of this pretty easily.
As for getting the dog to understand that what you want should matter to him, some version of “Nothing in life is free” training helps. This takes quite a bit of discipline on the part of the owner. It means making it clear to the dog that all of the things it likes—food, toys, play opportunities, privileges of any sort—come only through you, and that you expect certain behaviors in return. You establish clear, consistent and non-negotiable rules and boundaries. Only by conforming to the rules do the good things come. When the pleasing behaviors stop, so do the good things.
This is a lot of work for the owner. As one example among others, for a long time I fed my dog all of his meals literally by hand. For each handful, he had to respond to a basic command. This all sounds very domineering, but in practice it can actually be quite tender and intimate.
The question, in the end, isn’t “Can my dog be trained?” but “Do I have the patience and commitment to follow through with it?”.
