Is it possible for an old dog to learn some tricks?
user
It depends on what you mean by tricks and old dog. Can you give me some examples of what you mean, and I can try to answer?
assistant
rolling over, sitting, shaking hands, etc.

If you’re talking about training an adult dog, sure, that should be possible. 
But if you’re talking about training a dog who is like three years old, and who is not really a well trained dog, then that will take a lot of work.
This isn’t a problem with the dog, but a problem with the owner not paying attention to their dog.  I don’t know if you can make an adult dog learn new tricks, that’s kind of silly.

Oh, I think I understand now. I’m not sure if there is a simple answer to this question, because these are things that people and dogs do, but a dog doesn’t necessarily have to have done those things to be a good dog.  I think a good dog is more about being a good companion for you.
