I think it can be just fine. Who knows, the pup might even bring some extra life and challenges to the older dog. Just monitor them very closely at first and make sure they are not fighting roughly.

I added a geriatric 10-year-old to my family that included an exhuberant 2-year-old, and I had problems initially with the 2-year-old becoming toy possessive. He would beat the tar out of the 10-year-old.

Since the 10-year-old was half the size of the 2-year-old, I couldn't allow them to work it out on their own. Instead, I took control of all the toys in the house, and passed them out and put them away as I saw fit. I also leashed my aggressor during toy time.

Before long, the beatings stopped. Now, two years later, they are best friends. Well, good friends, and there have been no "fights" in more than a year.
