You might try seperating them for awhile. If they whine and and make a fuss while trying to get back together; you can be pretty doggoned sure it's either hormones or the anal gland.

If it's dominance, (which I doubt) they'll work it out before too long.
They are both Neutered. They usually go out seperately, and when Rocky is out, Duke will whine. When duke is out, Rocky could care less. But Duke also has Seperation Anxiety, so not sure if that is why he whines. But Duke is also known as a pretty good Whiner, as It dosent take much to get him to Whine!

There are no unfixed females around that I know of, but the neighbors just recently adopted a female dog, and she comes over all the time, and torments the dogs trough the fence, but she is fixed, or so the owners say.
