i agree with the neutral territory. also, go into it with a positive attitude. if you show up thinking a fight is going to break out, and nervous your pupper will pick up on it and get upset. he'll be jittery and nervous, and more likely to snap. if you go into it happy he'll go into it happy though. walk all of them before you meet up, and make sure they're tired! that way they don't get quite so excited. also, i've heard walking them together helps, because they're meeting but can't really do anything if you set a brisk pace, just keep them a few feet apart at first, then move closer together. baby gates are great, but i've found that axle will barge through them if he wants something bad enough, it just depends on your dog. some respect them, some don't.
