I wouldn't depend on it. I've heard that as well, but I have yet to see it happen after probably fifty clients now that got a puppy expecting it to get cues from an older dog. They come to me months later with a dog that's an absolute mess because they've left so much up to the puppy to just catch on to. I would take an active role in teaching the puppy boundaries, not only because it probably will not learn them from the older dog but also because taking an active role in a puppy's life is better for building your relationship with him.
oh I absolutely plan on working with the pup on a daily basis and not relying soley on my dog now to make him an outstanding dog lol I was just wondering if having my current dog around would be beneficial at all or not
