Yes, he is neutered and he's 2 years old.

and thank you for the posts, I will definetly look into those books!

My red basenji has lately been showing signs of possible dog aggression. A few months ago he never got into any fights or anything, but now he's launching himself onto other dogs and trying to fight them. He's never drawn blood or actually hurt another dog, but it's frightening how he's so unpredictable with other dogs. He might go in for a quick booty sniff and in a split second start snarling in the dog's face. It's quite scary, but like I said he's never actually hurt another dog, but what does it mean?
Its hard to tell when he's going to attack because his hackles raise everytime a dog comes into sight, so I can't tell wether he will or wont attack. Most of the time he is friendly and doesn't particularly care.

Even if the other dog isin't showing signs of aggression, he'll go for them. I've also noticed he hates large black dogs, chow chows, and labradors especially, as well as that he is more likely to attack when he's on the leash (he's usually walked off-leash in a safe area).

There was once an encounter where he attacked his own basenji kin! I thought basenjis got along together.

Is it just me? He's otherwise a very friendly basenji and loves to play.

Help, please? I don't want my basenji to get hurt.
