My wife and I just adopted 2 beautiful australian shepherds and corgi mix puppies about 6 months old. Had them for about 3 days and they were fine until the 4th day they started growling and eventually were fighting with each other, and i mean teeth showing and attacking each other. They are both males from the same litter. They are not neutered yet, my question is, does that have anything to do with this behavior, or is it jealously, or what. Concerned and looking for feedback, Thank you
The are both reaching sexual maturity, and probably fighting for domanince. I would have them nuetered asap. They still may fight a bit it is natural. What you don't want is blood shed. Littermates almost always have some sibling rivilry.
