Eko is not neutered and 2 years old, he has gone after females, but he shows aggression to any dog besides his female packmate Xena
Eko was more often then not the instigator, he pulled and then growled and then started snapping. I think in his case it's just that any dog that sets him off.
When Xena was about 4-5 months old an older male pit bull attacked her over a piece of asparagus :/ He was about 1, neutered. They went after it at the same time.
